This five-pack is ideal for landlords, property managers, and anyone who maintains multiple kitchens, because a blown fuse can knock out a microwave in an apartment or office break room without warning. Each 20 amp 250 volt fuse measures 0.24 by 1.2 inches and fits GE WB27X10388 applications, so repairs stay consistent across several appliances.

3. WE1X21975 Ceramic Dryer Fuse 30 Amp 250V
The standout feature of this replacement is its ceramic construction, which handles the intense heat of a clothes dryer far better than the glass fuses many people mistakenly install. Rated at 30 amps and 250 volts, the WE1X21975 fuse replaces GE part 4248223 and 3AB, delivering dependable circuit protection for dryers that overheat or fail mid-cycle. The two-pack means you can replace a blown fuse and keep a spare ready.
Beyond the material, this fuse earns praise for its exact fit in GE dryers, eliminating the guesswork that comes with generic alternatives.

This fuse is best for DIYers comfortable removing a dryer’s rear panel and testing the old fuse with a multimeter. It also suits appliance repair beginners who follow a simple tutorial, since the part drops in cleanly. Note that it is designed for dryers rather than microwaves, so confirm your model before ordering.

4. 5 Pack 20 Amp 125V Microwave Fuse 5304509451
Many people grow annoyed buying single fuses that fail within months, only to reorder again and again. This five-pack of 5304509451 replacements takes the opposite approach, giving you lasting stock for GE, Frigidaire, and Kenmore microwaves at 20 amps and 125 volts. Instead of replacing 1810711 or AP4980426 one at a time, you install one fuse and stash the rest in a drawer, ready for the next surprise failure.
The clear benefit is long-term savings, since bulk pricing per fuse runs well below retail singles. Each fuse matches OEM specifications closely, so fitment is straightforward across a wide range of over-the-range and countertop models. Reviewers highlight that their microwaves power up immediately after installation, with no humming or intermittent heating. The pack also suits households where one blown fuse often signals an aging appliance that may blow again soon.
This option is best for homeowners with older microwaves or anyone who has replaced a fuse once and expects another failure. It is also a practical pick for small repair shops that want affordable inventory on the shelf. Installation requires a screwdriver and about ten minutes, with the unit unplugged for safety. If you are tired of repeat purchases, this five-pack ends the cycle and keeps your kitchen running smoothly. (See Also:Microwave Rice Uncle Bens)

5. 20A 125V 6x30mm Microwave Fuse Pack of 5
Picture a Tuesday evening when your microwave stops mid-popcorn, dark and unresponsive while the rest of the kitchen works fine. That scenario is where this 20 amp 125 volt fuse pack shines, offering five 6 by 30 millimeter replacements for GE and Frigidaire models including WB27X11138 and 5304509451. Within minutes of unplugging the unit and swapping the blown fuse, your microwave is humming again and dinner is back on track.
The standout benefit is the generous five-count, which covers multiple appliances or repeat failures without another order.

6. GE-Compatible 20A Ceramic Microwave Fuse, 6 Pack
For the money, the GE-Compatible 20A Ceramic Microwave Fuse, 6 Pack gives you six replacement fuses without making you hunt for one at a time. The 20-amp, 250-volt slow-blow ceramic format targets common household microwave applications, while the 6 mm by 32 mm dimensions make model matching straightforward. It is a practical stock-up option for the price. That appeals to careful homeowners seeking simple backups.
The multi-brand claim is useful for households that own a GE, Whirlpool, or Kenmore unit, but compatibility still depends on the required amperage, voltage, physical size, and time-delay characteristic. This pack specifically references GE part WB27X10388, so checking the old fuse or model documentation is important. Matching those details before ordering this inexpensive replacement online helps avoid buying a cartridge that looks similar but cannot serve the same role.
Once compatibility is confirmed, the six-piece quantity is the standout convenience: you can keep spares for a future failure instead of replacing only the one that tripped. The ceramic construction and slow-blow design also make this set more purposeful than carrying assorted low-cost fuses. It is best for handy owners comfortable identifying a failed fuse; uncertain users should confirm with a qualified technician before ordering or touching the appliance.
- Six matching pieces include practical repair spares
- 20A and 250V ratings align with the listed applications
- Slow-blow ceramic construction supports time-delay behavior
- 6 x 32 mm dimensions help narrow model matching
- GE WB27X10388 reference provides a clear starting point
- Stated compatibility covers GE, Whirlpool, and Kenmore models
- The universal-fit claim still requires exact electrical and size verification
- The 6 x 32 mm format will not suit models requiring another fuse length

7. GE and Frigidaire 20A Microwave Fuse, 10 Pack
A tripped microwave can derail a quick breakfast or reheating dinner, especially when a visibly intact fuse turns out to be the problem. The GE and Frigidaire 20A Microwave Fuse, 10 Pack offers ten matching replacements for that frustrating interruption. Each 5304509451 fuse is rated at 20 amps and 125 volts, giving owners a convenient way to replace a confirmed failed part without a second trip to the store.
The ten-piece format is the real everyday advantage: one bad fuse no longer leaves you searching for another compatible spare, and the extras can sit in a utility drawer. The stated GE and Frigidaire focus makes this set less random than a mixed assortment. That said, the 20-amp, 125-volt rating is specific, and a household microwave requiring a 250-volt fuse should not assume this cartridge is interchangeable.
Before buying, compare the number printed on the existing fuse with the appliance documentation, and check whether the replacement calls for 5304509451. Similar microwave fuse numbers can differ in current, voltage, physical length, or timing behavior. The product is best for someone who has already identified the exact failed component and wants several on hand; it is not a substitute for investigating why the original fuse failed.
- Ten-piece pack reduces repeat shopping for a matching spare
- 20A and 125V ratings are clearly identified
- Part number 5304509451 supports exact model matching
- Listed applications target GE and Frigidaire microwaves

8. GE-Compatible 20A Slow-Blow Microwave Fuse, 5 Pack
This is ideal for homeowners or repair technicians who have a microwave requiring a 20-amp, 250-volt slow-blow ceramic fuse and can verify the 6 x 30 mm dimensions. The GE-Compatible 20A Slow-Blow Microwave Fuse, 5 Pack provides five matching units, enough to replace the failed part and retain several useful backups. It is especially sensible for GE and other compatible models that use this exact electrical and physical format.
The five-pack balances repair readiness with less excess stock than a larger multipack. Its slow-blow time-delay behavior is the key specification to compare with the original component, not merely the amperage or shape. Ceramic construction suits the replacement role, but buyers should locate the part number and appliance requirements. A microwave that calls for 250 volts should not be paired with a lower-rated fuse because the cartridge appears similar.
Once the specifications line up, installation can restore normal operation after a failed fuse, and keeping the remaining four units helps prevent another maintenance trip. The multipack is also practical preparedness for landlords, property managers, or homeowners maintaining several compatible appliances. It is not a diagnosis of underlying electrical faults. If the new fuse trips, the oven should be inspected rather than fitted with a higher-rated or faster-acting component.
- Five matched units cover the repair and provide useful spares
- 20A and 250V ratings match the stated applications
- Slow-blow timing behavior suits compatible replacement circuits
- Ceramic construction supports the required time-delay format
- 6 x 30 mm dimensions help identify the correct physical match
- Moderate pack size suits one repair or a small maintenance kit
- Exact 20A, 250V, slow-blow, and 6 x 30 mm specifications are required
- It is not a universal option across all GE or other microwave models

9. GE KSD201 110°C Microwave Thermal Fuse, 2 Pack
The standout feature is the clearly stated 110°C thermal cutoff rating. The GE KSD201 110°C Microwave Thermal Fuse, 2 Pack gives owners two temperature-sensitive replacement switches for compatible GE appliances, reducing the need for another urgent trip after one has failed. It is particularly useful for repair-minded households that know their model requires the KSD201 component and understand that the thermal switch is part of a broader safety system.
Having a two-pack is a meaningful convenience because the second unit can remain a ready spare or serve another identical appliance. The package does not make every thermal problem interchangeable, and visual similarity is not enough. Confirm the KSD201 designation, 110°C temperature rating, physical form, lead length, and wiring arrangement before ordering, then compare every specification directly with the component actually removed from the oven.
The practical benefit appears when a compatible KSD201 has opened after excessive heat, as replacing the failed component can return the microwave to service after the underlying cause is addressed. The pair is best for owners or maintenance professionals handling more than one unit, not for diagnosing an oven that trips repeatedly. A replacement thermal fuse is not a cure for blocked ventilation, damaged wiring, or unresolved overheating.
- Clearly specified 110°C thermal cutoff rating
- KSD201 designation supports precise part matching
- Two-pack includes a ready spare for another compatible repair
- Intended for listed GE microwave thermal-safety applications
- Helpful for owners or technicians maintaining multiple matching units
- Physical fit, lead arrangement, wiring, and model requirements must be confirmed
- A failed thermal fuse does not identify or repair the underlying overheating cause

10. GE-Compatible 20A Ceramic Microwave Fuse, 10 Pack
Unlike the common annoyance of receiving a so-called universal fuse that does not quite fit, this set clearly states 20 amps, 250 volts, slow-blow ceramic construction, and 6 x 30 mm dimensions. The GE-Compatible 20A Ceramic Microwave Fuse, 10 Pack gives buyers ten matching replacements for the specified GE WB27X10388 and compatible Whirlpool, Kenmore, and other microwave applications. Specific details are more reassuring than a vague fit claim.
The ten-piece quantity tackles another familiar problem: one replacement can be installed and the rest kept on hand, so a future failure does not mean another shopping trip. It is also a sensible choice for landlords, repair technicians, or households with multiple compatible ovens. The dimensions and slow-blow timing should still be checked against model or service documentation because brand compatibility cannot account for every similar-looking microwave.
When the model calls for a 20-amp, 250-volt, 6 x 30 mm time-delay fuse, the multipack is useful preparedness rather than a gamble. It is best for people who can identify the replacement requirement, including the reference to WB27X10388. Do not use it to bypass a fuse that keeps opening; repeated failure calls for investigating wiring, airflow, or other components. Properly matched, it offers spares at a convenient quantity.
- Ten matching 20A and 250V fuses provide ready spares
- Slow-blow ceramic design suits time-delay replacement applications
- Exact 6 x 30 mm dimensions reduce fit ambiguity
- WB27X10388 reference aids replacement selection
- Stated compatibility includes Whirlpool and Kenmore models
- Large count suits multiple units or maintenance inventory
- The broad compatibility claim still depends on exact model and electrical requirements
- It will not fit models requiring a different current, voltage, length, or timing behavior

What to Look for When Buying Ge Microwave Thermal Fuse
1. What Is a ge microwave thermal fuse?
A thermal fuse is a small safety component that cuts power to a microwave when internal temperatures rise beyond safe limits. It protects the appliance from overheating, which can damage internal parts or create a fire hazard. When a microwave runs but stops heating, or shuts off unexpectedly, a blown fuse is a common cause. This part suits DIY repairers, appliance technicians, and anyone who wants to extend the life of an older unit instead of replacing it. Homeowners with basic tool skills benefit most, since installation is usually quick and straightforward.
2. Key Features That Actually Matter
Not every replacement fuse delivers the same performance, so focus on the details that affect daily use and longevity.
- Performance in everyday scenarios matters because the fuse must respond reliably during heavy cooking sessions and repeated high-heat cycles.
- Build quality and durability determine whether the part survives years of use or fails prematurely after a few months.
- Ease of setup and maintenance saves time, especially for first-time repairers working without professional tools.
- Size, capacity, and fit are critical, since a mismatched fuse will not install correctly or function safely.
- Value at different budgets varies widely, and the cheapest option is not always the most cost-effective over time.
- Brand reliability and warranty coverage give peace of mind if the part arrives defective or fails early.
- Compatibility with existing setups ensures the fuse works with your specific microwave model and electrical configuration.
3. How to Choose the Right ge microwave thermal fuse
Start by checking how often you use your microwave. A household that reheats meals daily needs a more robust part than an occasional-use kitchen. Next, set a realistic budget and decide whether you want a basic replacement or a higher-grade component with extra durability. Match your expectations to the Top 10 list above: entry-level picks handle light duty, while higher-priced options suit heavy use or professional repair work. Always confirm the part number against your appliance manual before buying, and consider purchasing a spare if you rely on the microwave constantly. (See Also:Nostalgia Retrowave Microwave)
4. Common Buyer Mistakes to Avoid
- Buying without verifying the model number leads to incompatible parts that cannot be installed, so always confirm the part number against your manual first.
- Choosing solely by price often results in low-quality fuses that blow quickly, so weigh build quality and warranty before comparing costs.
- Skipping safety steps like unplugging the unit before repair risks electric shock, so always disconnect power and discharge the capacitor first.
- Ignoring the root cause means replacing a fuse that keeps blowing due to another failing component, so test the appliance thoroughly before ordering.
- Overlooking return policies leaves buyers stuck with defective parts, so check warranty terms and return windows before ordering.
Frequently Asked Questions About Ge Microwave Thermal Fuse
How do I know if my thermal fuse needs replacing?
If your microwave runs but does not heat, or shuts off during a cycle, a blown thermal fuse is a likely cause. You can test the fuse with a multimeter to check for continuity. If there is no continuity, the fuse has failed and should be replaced promptly to restore safe operation.
Will any thermal fuse fit my microwave model?
Not necessarily. Microwaves vary in design, voltage, and fuse ratings, so a universal fit is not guaranteed. Check your appliance manual or the existing fuse for the correct part number and amperage. Installing an incorrect fuse can create safety hazards or fail to protect the appliance, so verification before purchase is essential.
How long does a typical thermal fuse last?
A quality thermal fuse typically lasts several years, often matching the lifespan of the microwave itself. However, frequent heavy use, poor ventilation, or failing internal components can shorten its life. If a new fuse blows repeatedly, the underlying issue likely lies elsewhere in the appliance and should be diagnosed by a qualified technician.
Can I replace the fuse myself without professional help?
Yes, most replacements are straightforward for people comfortable with basic tools and safety precautions. Unplug the microwave, remove the outer panel, locate the fuse, and disconnect the terminals. Take photos during disassembly to simplify reassembly. If you feel unsure about any step, hiring a professional technician is the safer and smarter choice.
Are higher-priced fuses worth the extra cost?
Often, yes. Higher-priced fuses usually feature better materials and stricter quality control, which translates to more consistent performance and longer service life. For a heavily used microwave, the extra investment can prevent repeat failures. For occasional use, a mid-range option may offer the best balance between reliability and overall value.
What tools do I need for the replacement?
Basic tools are usually sufficient, including a screwdriver set, a multimeter for testing continuity, and possibly needle-nose pliers. Some models require a Torx driver for panel screws. Having the correct tools ready before starting keeps the repair quick and reduces the risk of damaging the appliance or injuring yourself during the process.
Is it safe to keep using a microwave after a blown fuse?
No, continued use without a functioning thermal fuse is unsafe because the appliance loses its overheating protection. Replace the fuse before operating the microwave again. If the replacement blows immediately, stop using the unit and consult a technician, as a deeper electrical or component fault may be present and require professional attention.
Final Verdict
Choosing the right ge microwave thermal fuse comes down to compatibility, build quality, and realistic expectations for your cooking habits.
