The bulb produces 400 lumens from 40 watts, which is enough to illuminate an oven or range hood without being unusually bright. Its stated maximum operating temperature is 300°C, or 570°F. The A15 body measures approximately 48 millimeters wide and 85 millimeters tall, giving buyers a relatively compact option for fixtures where clearance is limited.
The main trade-off is that the product is sold as one bulb rather than a multipack, so households replacing several fixtures may need more than one purchase. Its listed 1,000-hour lifetime is also shorter than several competing models, and its 4.3 rating is lower than the ratings attached to most of the other options in this guide.
This is a sensible choice for an A15 fixture that accepts an E26 base and needs warm, heat-resistant illumination. It is especially useful for a refrigerator, over-stove range hood, microwave, or other compatible appliance. Buyers should verify both the base and physical dimensions before ordering, particularly if the original fixture uses an unusual cover or lamp housing.
A Compact Option for Constrained Fixtures
The standard A15 profile and modest dimensions can make installation easier where a larger G45 globe would not fit. Measure the available space and compare it with the listed 48-by-85-millimeter size before purchase.
Warm Light for Everyday Appliances
At 2700K, the soft warm-white output is gentler than stark daylight and remains suitable for refrigerators, microwaves, range hoods, and selected general household fixtures.

This incandescent bulb operates on standard 110- to 120-volt household power and is designed to withstand temperatures up to 570°F, equivalent to 300°C. It can be used in ovens, oven hoods, microwaves, refrigerators, ceiling fans, outdoor lighting, and other compatible fixtures. The E26/E27 base and lead-free construction make it broadly relevant, although buyers should confirm the socket type.
An approximate lifespan of 2,000 hours gives the product a useful operating-life estimate, though actual results depend on voltage, temperature, usage patterns, and manufacturing tolerances. As with any incandescent bulb, it consumes more energy than an LED alternative, and heat resistance does not mean the fixture itself is suitable for any installation.
This bulb is a strong recommendation for anyone replacing a standard 40-watt G45 appliance lamp, especially when a backup bulb is useful. It is also a good fit for range hoods, refrigerators, microwaves, and outdoor fixtures that accept the medium base. Verify the socket, wattage allowance, glass-envelope clearance, and appliance manufacturer guidance before installation.
Useful Output in Demanding Locations
The 400-lumen output provides clear visibility without excessive brightness. That balance makes the bulb useful for checking an oven cavity or locating items inside a refrigerator.
A Ready Spare for Common Fixtures
Two bulbs are included, reducing the inconvenience of ordering separately when another compatible appliance lamp needs replacement. The medium base also makes the pair adaptable to a broad range of fixtures.

We may earn a commission when you buy through this link, at no additional cost to you.
Heat management is a central selling point. Visther specifies a brass base and special silicone sealing to support heat dissipation and durability in a high-temperature environment. The bulbs are rated to withstand up to 300°C, or 570°F, and use an E26 medium base that fits many ovens, microwaves, refrigerators, and household lighting fixtures.
The listed lifespan reaches approximately 1.7 years, giving buyers a more concrete longevity expectation than many competing descriptions. The product is also described as lead-free. One limitation is that it remains an incandescent option, so it does not provide the lower energy use associated with LED lighting, and no separate dimming range is stated.
This is a compelling pick for a 120-volt G45 fixture that benefits from brighter 415-lumen output and two included lamps. Choose it when your appliance accepts a standard E26 base and the manufacturer approves a 40-watt incandescent replacement. Confirm that the bulb has enough clearance and compare the G45 dimensions with the existing lamp when necessary.
Heat Management Built Into the Base
The brass base and silicone seal are designed to dissipate heat effectively. Those construction details support reliable operation in appliance locations where temperature fluctuations are routine.
Two Strong General-Purpose Bulbs
Beyond appliance lighting, the E26 base and 415-lumen output make these bulbs potentially useful for string lights, garden fixtures, hanging lamps, and other household applications that accept a 40-watt incandescent bulb.

4. G45 High-Temp 40-Watt – Convenient Four-Pack Coverage
G45 High-Temp 40-Watt
G45 bulb shape
E26/E27 medium base
415-lumen output
Four-bulb package
This four-pack is aimed at households that want several replacement bulbs readily available. It has a 4.5 rating and uses the standard G45 shape, making it relevant to many ovens, ranges, and stoves. Its 415-lumen output is comparable with other high-output incandescent choices in the guide.
Pros
- Four bulbs in one package
- Wide 110–130-volt range
- 570°F heat tolerance
- Sealed heat-dissipation design
Cons
- Larger pack may be unnecessary
- Bulb width requires clearance
We may earn a commission when you buy through this link, at no additional cost to you.
The bulbs operate across 110-, 120-, and 130-volt systems and are rated for temperatures up to 570°F, or 300°C. Special seal silicone and an E26/E27 medium socket are included to improve heat dissipation and durability. Each bulb has a stated life rating of 1,500 hours and is described as lead- and mercury-free.
A four-bulb package may be unnecessary for a single failed lamp, but it can be economical for landlords, landlords' maintenance kits, property managers, or owners of several compatible appliances. The globes measure approximately 2.76 inches wide by 1.77 inches long, so clearance beneath an appliance cover or inside a recessed housing deserves attention.
This is a practical pick for buyers who want the largest stock in the roundup and already know that their appliances use E26 sockets. It is less appropriate when a single replacement is needed or when the original appliance uses a smaller A15 bulb. Confirm the appliance wattage limit, base, shape, and physical clearance before ordering.
Four Bulbs for Repeated Maintenance
Keeping several matching bulbs on hand is useful for multi-appliance households and for maintaining a consistent replacement stock. It also reduces repeated ordering when heat exposure shortens bulb life.
Clearance Matters in Small Housings
The G45 globe is wider than an A15 bulb and may not suit tightly enclosed covers. Compare the stated dimensions with the replacement space rather than relying only on the shared E26 base.

Cons
- No stated heat rating
- Incandescent energy use
We may earn a commission when you buy through this link, at no additional cost to you.
Dimmability is a notable convenience because the bulbs are described as compatible with most dimmer switches. That can be helpful in range-hood or other appliance installations where a control supports multiple brightness levels. Each bulb is rated to last approximately 1.4 years based on the manufacturer's stated usage assumptions.
Unlike several oven-specific competitors, the supplied information does not state a maximum heat-resistance temperature. Appliance manufacturers often specify whether a lamp must be heat-rated, so buyers should check their appliance documentation before substituting this product for a bulb marked for oven use. Incandescent energy consumption is another inherent limitation.
This is a good option for refrigerators, range hoods, or other compatible A15 fixtures that do not require a documented high-temperature rating. It is also attractive for buyers seeking a widely recognizable replacement format and smooth dimming. Confirm the required base, wattage, color temperature, and any appliance-specific heat-rating requirement before purchase.
A Familiar Fit for Common Fixtures
The A15 shape and E26 base are common in household appliances, making this pair easier to evaluate against an existing bulb. The clear finish also supports the traditional appearance expected of many appliance fixtures.
Useful Dimming Compatibility
Compatibility with most dimmer switches can make the bulbs more versatile in controllable household fixtures. It does not mean every dimmer or appliance control is compatible, so existing manufacturer requirements should still be checked.

- Larger A15 dimensions
We may earn a commission when you buy through this link, at no additional cost to you.
The bulbs use a 40-watt, 110- to 130-volt electrical configuration with an E26/E27 medium base. They are designed to withstand temperatures up to 300°C and are listed for ovens, oven hoods, oven ranges, microwaves, refrigerators, night lights, sewing machines, and other small household appliances.
The supplied information does not provide a lumen figure or color temperature, so shoppers cannot directly compare its brightness and light quality with options that list 360 or 415 lumens. Its listed dimensions are approximately 3.5 inches by 2.2 inches, making a clearance check important in compact appliance housings. Incandescent energy use is also a consideration.
This is a strong option when longevity is the priority and the fixture accepts a standard medium-base A15 bulb. It may appeal to households replacing lamps in several compatible appliances or seeking fewer replacement cycles. Before buying, verify the appliance's wattage limit, socket size, heat-rating requirements, and available installation space.
A Long-Lasting Replacement Claim
The 2,500-hour rating is a meaningful distinction in this category. Actual service life will vary with heat, voltage, switching frequency, and manufacturing tolerances, but the claim suggests fewer planned replacements.
One Format for Several Appliances
The broad application list covers cooking appliances, refrigeration, and smaller household fixtures. That flexibility is useful, provided each destination accepts a 40-watt A15 incandescent lamp.

E26 brass base
360-lumen output
1,500-hour rated life
This G45 bulb offers a 4.5 rating and a useful combination of 360 lumens, dimmability, and heat resistance. The E26 brass base is designed to improve heat dissipation, while the stated maximum temperature of 300°C supports use in demanding appliance locations.
Pros
- Compact 360-lumen output
- Brass base improves dissipation
- Dimmable across 10–100%
- Wide fixture compatibility
Cons
- Lower output than 415-lumen rivals
- Two-pack title wording unclear
We may earn a commission when you buy through this link, at no additional cost to you.
Light quality is specified as warm white at 2700K, with a 270-degree beam angle. The bulb is described as dimmable from 10% to 100%, giving users a more precise brightness range than a simple on-and-off appliance lamp. Its rated life is approximately 1,500 hours per bulb, and the construction is described as lead-free.
The 360-lumen output is lower than the 400- and 415-lumen figures offered by several competitors, so people wanting maximum brightness may prefer another G45 option. The title does not make the package quantity especially clear, and buyers should verify the listing details before ordering. It is also an incandescent product rather than an LED assembly.
This bulb is best for a dimmable G45 fixture that needs warm light and reliable heat tolerance without maximum output. It can also be considered for microwave, refrigerator, range hood, porch, sconce, hanging lamp, garden light, and lava-lamp applications where the socket, wattage, and enclosure are appropriate. Check the original bulb and fixture instructions before substitution.
Controlled Brightness in Any Direction
The stated 10% to 100% dimming range is useful when a fixture supports compatible controls. A 270-degree beam gives broad coverage in an oven or range hood without concentrating light into one narrow point.
A Brass Base for Thermal Management
The brass E26 base is intended to release heat efficiently. It is a useful construction detail in an appliance bulb, where sustained heat can shorten service life or damage an unsuitable lamp.

8. WB08T10002 LED Assembly – Model-Specific Upgrade Option
WB08T10002 LED Light Assembly
LED replacement assembly
One-key switch operation
IP65 protection rating
Multiple compatible models
The WB08T10002 is fundamentally different from the other nine products because it is a model-specific LED wall-oven light assembly rather than a conventional replaceable bulb. Its 4.4 rating reflects a different buying proposition: buyers are selecting a complete component for a compatible GE or Kenmore oven, not simply matching wattage and socket.
Pros
- LED energy-saving design
- Specific model compatibility
- Long-life illumination
- Water-resistant protection
Cons
- Limited to listed models
- Assembly differs from bulb
We may earn a commission when you buy through this link, at no additional cost to you.
The assembly replaces several related part numbers, including AP2019709, 769452, AH230438, EA230438, PS230438, WB02T10115, WB02T10116, WB08T10044, WB2T10115, WB2T10116, and WB8T10002. The supplied model list includes several numbered units and named configurations, so careful comparison with the appliance's model number is essential.
Its one-key switch simplifies operation, while the LED design is described as energy saving and durable. An IP65 protection rating adds resistance to water and dust in maintenance, barbecue, camping, and similar settings. The important limitation is compatibility: unlike a universal E26 bulb, this assembly will not fit every oven, and incorrect installation could leave the appliance without a working light.
This is the premium pick for a homeowner who has confirmed that the oven requires part WB08T10002 or AP2019709 and that the model number appears in the compatibility information. It offers an integrated LED solution rather than another glass incandescent bulb. Disconnect electrical power before installation, wear work gloves, and follow the appliance service documentation.
An Integrated LED Solution
The assembly combines light and a one-key control in one replacement component. That design can appeal to owners who prefer LED longevity and lower energy use over a replaceable incandescent lamp.
Compatibility Must Come First
Model-specific parts eliminate much of the guesswork only when the exact appliance and replacement numbers match. Check the model label and existing part before ordering rather than relying on visual similarity.

9. Blakapoo A15 40-Watt – Detailed Dimmable A15 Replacement
Blakapoo A15 40-Watt
A15 bulb shape
E26/E27 medium base
360-lumen output
1,500-hour rated life
The Blakapoo A15 combines a 4.5 rating with unusually specific installation guidance. Its stated dimensions are 48 millimeters in diameter and 85 millimeters tall, while its clear A15 shape and standard E26/E27 base make it relevant to many common appliance and household fixtures.
Pros
- Detailed dimensional guidance
- Full 10–100% dimming range
- CRI above 90
- Broad range of applications
Cons
- Lower brightness than top rivals
- Dimensions require careful checking
We may earn a commission when you buy through this link, at no additional cost to you.
The bulb produces 360 lumens in warm white at 2700K, with a 270-degree beam angle. It is dimmable from 10% to 100%, allowing more precise control than a fixed-output replacement. A color-rendering index above 90 is also specified, which should make colors look more natural under the bulb compared with a less capable light source.
The stated life is up to 1,500 hours, and the product is described as containing neither mercury nor lead. As with other incandescent bulbs in the guide, energy use remains higher than it would be with LED lighting. Its 360-lumen output is also below the brightest 415-lumen options, making it better suited to comfortable utility lighting than maximum interior visibility.
This bulb is a good fit for an A15 medium-base fixture that accepts 40 watts and needs warm, adjustable light. The manufacturer recommends checking size before purchase, and that advice is important because a shared base does not guarantee enough room for the glass envelope. It can also serve compatible floor, table, ceiling, garden, hanging, and wall lamps.
Measurement Reduces Fitment Risk
Published dimensions and a labeled product image help shoppers compare the bulb with the existing lamp. Measuring the socket area and cover reduces the chance of discovering an obstruction only after delivery.
Natural Color and Fine Brightness Control
The stated CRI above 90 supports more accurate color perception, while the broad dimming range can reduce glare. These features are useful in a kitchen appliance or a household fixture where a single fixed level may be too harsh.

415-lumen output
Two-bulb package
The Jslinter G45 offers 415 lumens from a 40-watt bulb and carries a 4.5 rating. Its two-bulb package and high-temperature construction make it a credible option for ovens, ranges, stoves, and other compatible household appliances.
Pros
- High 415-lumen brightness
- 570°F heat tolerance
- Durable brass base
- Two bulbs included
Cons
- Incomplete dimension specification
- No explicit dimming claim
We may earn a commission when you buy through this link, at no additional cost to you.
The bulbs use a standard E26/E27 medium base, which supports broad fixture compatibility. Their brass base and high-temperature construction are intended to improve durability and heat dissipation, while the stated 570°F rating matches the leading heat-resistant options in the guide. The clear bulb design provides a traditional incandescent appearance.
The supplied product information is less complete than that of several competitors. It does not state a beam angle, color temperature, dimming capability, or a specific hour rating, and the dimensions line is incomplete. It is therefore harder to compare fine details such as enclosure clearance and light color before purchase. Incandescent energy use also remains a limitation.
This is a strong pick for a buyer who prioritizes bright output, a standard medium base, and two included heat-resistant bulbs. It is particularly suitable for a G45 oven lamp that accepts 40 watts. Before ordering, compare the globe dimensions with the original bulb, confirm the socket, and check the appliance manufacturer for heat-rating and wattage requirements.
Brightness for Darker Interiors
At 415 lumens, these bulbs provide more light than several 360- and 400-lumen alternatives. That can make them easier to see when checking an oven cavity or working near a range.
A Conventional Medium-Base Format
The E26/E27 base is widely recognized and makes the bulbs candidates for compatible appliance and general household fixtures. Shape and physical clearance still need to be verified before installation.

Buying Guide – How to Choose the Best Oven Light Bulb Replacement
The safest replacement is the one that matches the appliance manufacturer's requirements for bulb shape, base, wattage, voltage, heat tolerance, and dimming. The following factors help narrow the selection before you buy.
Confirm the Bulb Shape and Size
A15 and G45 bulbs can both use an E26 medium base, so the base alone does not guarantee a proper fit. A15 bulbs are narrower and more compact, while G45 bulbs use a larger, rounder envelope. An incorrect shape may interfere with a glass cover, reflector, door switch, or surrounding housing even when the thread connection appears correct. Measure the original bulb and the available clearance, then compare those measurements with the dimensions supplied by the replacement seller.
Match the manufacturer or seller dimensions before ordering, especially for an A15 model with a stated diameter of 48 millimeters and height of 85 millimeters. Do not force a bulb into a tight enclosure, and do not assume a larger G45 globe will rotate into the same space as an A15 bulb.
Match Voltage and Wattage
Most household oven and appliance lamps in this guide operate at 120 volts, although some products list compatibility from 110 to 130 volts. The wattage should also match the lamp being replaced unless the appliance manufacturer explicitly permits another value. A lower-wattage bulb can provide less illumination, while a higher-wattage bulb may exceed the socket or fixture rating. Electrical requirements are especially important for model-specific assemblies, which may not follow the standard 40-watt bulb format.
Use 40 watts and the voltage range specified for a conventional replacement, and never exceed the appliance's stated limit. If the appliance documentation is unavailable, compare the existing bulb, socket markings, and model information before choosing a product.
Evaluate Heat Resistance
An oven bulb must tolerate substantially more heat than a lamp in a living room. The products described as oven-compatible carry ratings of up to 300°C, or 570°F, although one title also references 500 degrees. A stated temperature rating is useful, but it is not a substitute for compliance with the appliance manufacturer's instructions. Some fixtures expose the bulb to more heat than others, and a bulb's location under a cover or inside a hot housing can affect operating conditions.
Choose a clearly heat-rated replacement for an oven, microwave, range hood, or similar high-temperature location. If the manufacturer requires a specific oven-rated bulb, do not substitute an ordinary household lamp even if the base appears identical.
Compare Light Output and Color
The listed outputs range from 360 lumens on the two Blakapoo options to 415 lumens on several G45 bulbs. More lumens can make an appliance interior easier to inspect, but a softer output may be more comfortable in a range hood. Color temperature is also useful information: a 2700K rating produces warm, soft-white light, while products without a stated color temperature leave more uncertainty about the final appearance. For consistent output, choose a bulb with both lumen and color-temperature information.
Around 400 lumens is a useful middle ground for most appliance-lighting tasks. Select the highest output needed for visibility and the warmest color that suits the space, while also considering whether the fixture supports dimming.
Check Dimmability and Controls
Some appliance bulbs are used behind appliance switches that offer low, medium, and high brightness. Two of the Blakapoo products explicitly advertise dimming, and the GE A15 is described as compatible with most dimmer switches. That does not mean every dimmer, appliance control, or LED driver will operate them correctly. A conventional incandescent bulb is generally more forgiving in many legacy dimming circuits, but the appliance documentation should still control the decision.
Look for a stated dimming range and confirm that the fixture's control is designed for the bulb type. If the original lamp was dimmable, replacing it with a fixed-output model may remove an expected feature.
Review Construction and Lifespan
Brass bases, silicone sealing, and lead-free construction are recurring construction details in this category. The claims are intended to improve heat dissipation, durability, and environmental characteristics, although a seller's lifespan estimate remains theoretical and varies with actual conditions. Listed ratings range from 1,000 hours for the first A15 option to 2,500 hours for the SalPhines pair, while some products provide no hour figure. Longer claims are attractive, but they should be considered alongside heat exposure and switching frequency.
Prioritize a product with a clear temperature rating and a credible construction description. Keep spare bulbs of the correct model available if the appliance runs hot or the lamp is switched frequently.
Choose the Correct Pack Size
The roundup ranges from one bulb to four bulbs. A single replacement makes sense for an isolated failed lamp, while a two-pack offers a spare for the same appliance or a second compatible fixture. Four bulbs can be useful for property maintenance or households with several matching appliances. Pack size should follow actual need rather than a promotional assumption, and every included bulb should have the same voltage, shape, base, and wattage as the original.
Choose a multipack when you can identify multiple valid locations or want a matching spare. For one lamp, buy only what is necessary and save the unused matching bulb for future replacement.
Distinguish Bulbs From Assemblies
Most products here are conventional incandescent bulbs intended to screw into an E26 socket. The WB08T10002 option is a complete LED light assembly for listed GE and Kenmore oven models. These categories are not interchangeable, and a model-specific assembly generally requires more careful identification than a universal bulb. It may include integrated controls and a different physical mounting arrangement. Using the wrong assembly can result in poor fitment, incorrect operation, or damage.
Check the appliance model number and original part label before choosing an assembly. For a standard bulb, check the socket and dimensions. Never force either type if its connection or mounting method differs from the original component.
How to Use and Care for Your Oven Light Bulb Replacement
Before replacing the lamp, switch off the appliance and disconnect it from electrical power according to the owner's manual. For a wall oven, disconnect the electrical supply before servicing. Allow the bulb and housing to cool completely, remove any glass cover only as directed by the manufacturer, and wear work gloves to protect your hands from sharp edges or a fragile bulb.
Compare the new bulb with the old one before installation. Confirm the shape, base, wattage, voltage, heat-rating requirement, and clearance. If the appliance uses a dimmer or appliance switch, verify that the replacement is compatible. Screw a conventional bulb into the socket gently until seated, without excessive force, and reinstall the cover only when the manufacturer allows it.
Restore power after the lamp and cover are correctly installed, then test the light with the door or appliance control. Turn the power off before removing a failed bulb. Do not touch a hot glass envelope with bare fingers, and do not use a replacement that shows cracks, discoloration, or damage. If the new bulb fails quickly, stop using it and check the socket, wattage limits, dimmer compatibility, and appliance wiring rather than repeatedly installing another bulb.
Frequently Asked Questions
Are all oven light bulbs interchangeable?
No. Appliance bulbs may share an E26 base while differing in A15 or G45 shape, wattage, heat rating, and dimming behavior. Model-specific LED assemblies are also not interchangeable with standard bulbs. Match the appliance manufacturer's requirements and compare the original component's size and markings before ordering.
What temperature should an oven light bulb withstand?
The oven-rated options in this guide are generally described as tolerating temperatures up to 300°C, or 570°F. A temperature claim still does not override an appliance manufacturer's specified lamp type. Use a heat-rated bulb for a hot appliance and avoid ordinary household bulbs unless the manual explicitly permits them.
Are E26 and E27 appliance bulb bases compatible?
E26 and E27 are physically similar medium-base designations, and several products are listed as compatible with both. Nevertheless, buyers should confirm the actual socket diameter, voltage, wattage limit, and appliance instructions. Fitment should be based on the labeled base and the fixture specifications rather than appearance alone.
Can I use a dimmable oven bulb in my appliance?
Only if the appliance control and manual support that bulb. Some options state compatibility with most dimmers, while two Blakapoo models advertise a 10% to 100% range. A dimmable bulb can still flicker or behave poorly with an incompatible control, so confirm the required compatibility before installation.
What is the difference between A15 and G45 oven bulbs?
The principal difference is physical size and shape. A15 bulbs are narrower and typically better for compact appliance fixtures, while G45 bulbs have a rounder, wider globe. Both may use an E26 medium base, so you should check dimensions and clearance rather than relying on the base alone.
Why does a replacement oven bulb fail quickly?
Rapid failure can result from excessive temperature, an incorrect wattage, an incompatible dimmer, a loose socket, moisture, or a defective fixture. It can also happen when a general household bulb is used in a location requiring an oven-rated lamp. Check the manual and all of these variables before replacing another bulb.
Do 40-watt appliance bulbs work in refrigerators?
Many of the listed bulbs are approved for refrigerators, microwaves, ranges, and oven hoods, but compatibility depends on the socket, wattage limit, and appliance design. A refrigerator may use a different A15 appliance bulb than an oven. Verify the original bulb and the refrigerator manual before making a substitution.
Should I choose an LED assembly or a standard replacement bulb?
Choose a standard heat-rated bulb when the appliance uses a replaceable E26 lamp and the manufacturer permits it. Choose a model-specific LED assembly when the oven documentation identifies that part or the appliance has an integrated LED module. The correct part is determined by the model number and original component, not by preference alone.
Final Thoughts on Choosing the Best Oven Light Bulb Replacement
The SouLight G45 is the strongest all-around option because it combines a 4.5 rating, 400-lumen output, 570°F heat resistance, broad appliance use, and two bulbs in a package. The GE A15 stands out as the budget pick with a 4.6 rating and familiar standard format, while the WB08T10002 LED assembly is the premium choice for compatible GE and Kenmore models.
For most conventional appliance fixtures, prioritize the required shape, E26 base, 40-watt rating, heat resistance, and physical clearance. Then compare brightness, dimming, lifespan, and package size. Model-specific parts demand a different process, so verify the appliance model and existing part before purchasing a complete assembly.
Availability and prices can change, and seller specifications may evolve over time. Before ordering, confirm the socket, wattage, voltage, dimensions, heat rating, and any manufacturer restrictions, then review the latest listing and current price for the replacement that fits your appliance.
