4. Frienda 20 Pcs Microwave Fuse, 20a 250v Slow-Blow Ceramic

A common annoyance with most microwave fuses is that they’re sold in tiny 1 or 2-packs, so if you have multiple microwaves at home or run a small appliance repair business, you’re constantly running out and paying separate shipping fees for small orders. The Frienda 20-Pack of 20A 250V slow-blow ceramic fuses eliminates that frustration entirely by giving you a massive bulk supply that will last for years of repairs and replacements. Each fuse is built to the same high standards as OEM parts, with a slow-blow ceramic design that prevents nuisance tripping during normal microwave operation, so you won’t waste fuses on minor power surges from the turntable or interior light.

The 250V rating makes these fuses compatible with both standard residential microwaves and higher-power commercial models, so you don’t have to keep two different types of fuses on hand for different appliances. For repair technicians, the large pack means you can complete multiple jobs without running out of parts, and for homeowners with a separate microwave in the kitchen, garage, and basement, you’ll have plenty of spares to handle any unexpected blowouts without a trip to the store.

5. 4-Pack Microwave Door Switch & 20A 250V Fuse Combo

Imagine your microwave suddenly stops working mid-reheat, and when you open the door to check on your food, the light doesn’t turn on and the turntable doesn’t spin. After a quick diagnostic, you realize both the door switch and the main 20A fuse are blown, meaning you’d normally have to order two separate parts and wait for two separate deliveries to fix the issue. This 4-pack of microwave oven door switches and 20A 250V slow-blow fuses solves that problem by bundling both common replacement parts together, so you can fix your microwave in one go without the hassle of multiple orders. Each fuse in the pack is a universal slow-blow ceramic design rated for 250V, so it handles the high power draws of standard microwaves without tripping unnecessarily, and the door switches are built to match the exact fit and function of OEM parts for most major microwave brands.

The combo pack is perfect for anyone who does their own appliance repairs, as it covers two of the most common failure points in microwaves, saving you time and money compared to buying parts separately. Installation is straightforward for both parts: the fuse slides directly into the standard fuse slot, and the door switch snaps into place with no wiring modifications needed for most models.

6. BlueStars WB27X10388 Ceramic Microwave Fuse 5-Pack

For the price, the BlueStars WB27X10388 Ceramic Microwave Fuse 5-Pack is a practical repair kit: five 20-amp, 250-volt ceramic fuses designed to replace the WB27X10388 part number. You get useful inventory for several compatible units or future failures, plus clearly stated ratings, without purchasing replacements one at a time. That balance of quantity and specification makes it especially appealing to prepared homeowners and technicians servicing several compatible appliances.

The ceramic format provides the specified construction for compatible Kenmore and other supported models, while the five-piece quantity supports multiple repairs or keeps spares available. The pack is especially handy for landlords, repair technicians, or households that want to avoid a second trip to the parts seller. Always unplug the microwave, safely discharge high-voltage capacitors, and confirm the part number and ratings before installation; then follow service guidance.

In everyday use, the main benefit is straightforward: one matching fuse can restore operation after an electrical fault, provided the microwave itself is otherwise sound. Installation is usually a matter of removing the old fuse and fitting the new one in the proper holder. A multimeter and appliance manual can help verify continuity and placement, making this a sensible DIY-oriented option for anyone comfortable with microwave safety procedures.

• Five-fuse pack supports multiple repairs and future replacements.
• Clearly stated 20A and 250V ratings aid matching.
• Exact WB27X10388 number simplifies precise ordering.
• Ceramic format matches the specified replacement type.
• Useful stock for technicians or households with several compatible appliances.
• One included spare remains after a single repair.

• A five-pack may be unnecessary for a single-appliance owner.
• Compatibility still depends on confirming the model and electrical specification.

7. GE, Frigidaire, Kenmore 20A 125V Microwave Fuse 5-Pack

A blown fuse can turn a simple reheating job into a frustrating trip to the repair counter, especially when the original part number is hard to identify. The GE, Frigidaire, Kenmore 20A 125V Microwave Fuse 5-Pack targets that problem with five 5304509451 replacements, each rated for 20 amps at 125 volts and listed for several common GE and Frigidaire part numbers. That kind of confusion is a familiar household inconvenience.

Having several fuses on hand is useful for older microwaves that share this specification, whether the failed fuse uses 1810711, EA3486694, PS3486694, AH3486694, or AP4980426 numbering. Before buying, compare the number printed on the existing fuse with the appliance manual, inspect the holder, and check the required amperage and voltage. A similar-looking component is not automatically a safe or correct substitute for the microwave’s protection circuit.

Once compatibility is confirmed, replacing a failed fuse is a small but meaningful repair that can return a sound microwave to service without replacing the whole appliance. The five-pack also gives owners a spare for later, though five may be more than a single household needs. Use insulated tools, unplug the unit, and discharge capacitors according to the service guidance before touching the fuse housing.

• Five matching 5304509451 fuses simplify restocking.
• Listed cross-references cover five common replacement numbers.
• The 20A and 125V ratings are clearly identified.
• Useful stock for older compatible microwave models.
• Supports one immediate repair while leaving spares.
• Clear part identification makes cross-referencing easier.

• Electrical specifications must still match the appliance.
• Five fuses may be excessive for a single microwave.

8. WB27X10388 20A 250V Slow-Blow Ceramic Fuse 6-Pack

The WB27X10388 20A 250V Slow-Blow Ceramic Fuse 6-Pack is ideal for repair technicians, landlords or property managers, and experienced DIY owners servicing compatible Kenmore, Whirlpool, or GE microwaves. Its 6 mm by 32 mm ceramic units directly replace WB27X10388 parts and are specified at 20 amps and 250 volts, but the appliance manual and original fuse markings should still confirm every detail against the specific model before purchase.

The six-piece quantity is useful when maintaining several appliances or keeping matching spares, and slow-blow timing is appropriate only for circuits designed for that characteristic. Visually, the stated 6 mm by 32 mm size helps narrow the search, yet physical dimensions alone do not establish compatibility. Check the fuse holder, wiring diagram, and model requirements, and avoid assuming that a higher-voltage or different-timing fuse is interchangeable merely because it fits.

For a confirmed match, replacing the failed component can restore normal power without buying a new microwave, provided no separate fault such as a shorted diode or damaged wiring is present. Installation should be performed with the microwave unplugged and its capacitor safely discharged. The straightforward cylinder-and-holder design appeals to people comfortable with basic appliance repair, while unfamiliar owners should use a qualified technician and follow model-specific service guidance.

• Six matching replacements support multiple repairs.
• Direct WB27X10388 replacement simplifies model matching.
• Stated 6 mm by 32 mm dimensions aid fit checks.
• The 20A and 250V ratings are clearly identified.
• Slow-blow ceramic type suits compatible circuits.
• Bulk packaging is useful for technicians and landlords.

• The broad universal-fit claim still requires model-level confirmation.
• Required voltage and timing characteristics must be verified.

9. GE, Frigidaire, Kenmore 20A 125V Microwave Fuse 2-Pack

The standout feature is broad replacement-number coverage: the GE, Frigidaire, Kenmore 20A 125V Microwave Fuse 2-Pack is listed to replace 1810711, EA3486694, PS3486694, AH3486694, and AP4980426. That makes it convenient for owners who have lost the paperwork and need to match an existing number, while still requiring confirmation that the holder, 20-amp rating, and 125-volt specification align with the appliance documentation before ordering or installing the correct part.

Two pieces are a more measured quantity for a single household than a bulk pack, yet they still allow one working replacement and one spare. The 5304509451 identification is useful during ordering, and the stated electrical values let buyers compare the part directly with the old fuse. Do not rely on visual similarity alone; microwave fuse holders and circuitry must accept the specified rating and configuration.

If the numbers and ratings match, a failed fuse can be replaced without purchasing an entire microwave, making this a practical repair for an otherwise healthy unit. The compact two-pack is especially suitable for one appliance or a small collection of compatible models. Unplug the appliance and discharge high-voltage capacitors before service, and investigate other electrical faults if a new fuse blows again, sparks, or shows scorching.

• Broad replacement-number coverage simplifies cross-referencing.
• Two-pack provides one working fuse and one spare.
• The 20A and 125V specifications are clearly stated.
• The 5304509451 identifier supports precise ordering.
• Sensible quantity for one or two compatible appliances.
• Helpful when original appliance documentation is unavailable.

• The two-piece count is limited for multi-unit maintenance.
• Cross-reference alone does not guarantee electrical compatibility.

10. GE, Frigidaire 20A 125V Microwave Fuse 10-Pack

Unlike common single-fuse listings that leave owners making a second order after discovering the wrong replacement, this 10-piece pack makes model matching easier by repeating the 5304509451 number and 20A 125V specification across the supply. The GE, Frigidaire 20A 125V Microwave Fuse 10-Pack is a convenient choice for technicians or households maintaining several compatible GE or Frigidaire microwaves, though quantity never replaces proper compatibility checks before purchase.

The larger count is useful for repair shops, landlords, or multiple compatible units because it reduces repeated ordering and keeps standardized replacements nearby. Each fuse should be compared with the part number and electrical markings on the appliance or existing fuse. A fit in the holder is not enough by itself: current, voltage, dimensions, and whether the circuit expects a fast- or slow-blow characteristic all need to be verified.

When a correct replacement is all the failed component needs, the ten-pack can get a compatible microwave operating again while leaving spares for future service. Installation still requires unplugging the unit, safe capacitor discharge, and careful attention to the holder contacts and seating. If a replacement blows immediately, stop testing and diagnose the underlying circuit rather than assuming every symptom is always just a bad fuse.

• Ten-pack reduces repeat orders for multiple compatible units.
• Consistent 5304509451 identification simplifies matching.
• The 20A and 125V ratings are clearly stated.
• Bulk supply suits repair technicians and landlords.
• Multiple on-hand units can reduce service downtime.
• Each fuse carries the same listed replacement number.

• Ten fuses may be excessive for a single-appliance household.
