ExploreHome: 2 Pcs 20 Amp 125 Volt 611 Fuses for GE/Frigidaire
The ExploreHome set consists of two 20A, 125V microwave fuses designed to replace models WB27X11138 and related numbers. These fuses measure 6 mm by 30 mm, a common format across many GE and Frigidaire units. They provide overcurrent protection to shield the microwave circuitry from surges and faults. Use them when the original part numbers include WB27X11138 or the listed replacements to restore standard operation after a fuse blow.
Compatibility and safety notes
These fuses are intended for 20A, 125V circuits. Do not exceed the specified amperage or voltage, as that can compromise safety. Confirm the microwave’s model matches the 6×30 mm form factor before installation. If the fuse blows immediately after replacement, inspect related components such as the door switch or high-voltage circuitry for faults that could cause repeated blowouts.
FBULWSEC: 2 Pack 20A 125V Microwave Fuses (530450945120A)
This 2-pack from FBULWSEC covers 20A, 125V requirements and lists compatibility with GE, Kenmore, and Frigidaire models, including 1810711 and 5304509451 families. It notes model replacements such as EA3486694 and AP4980426. A practical tip is to check the microwave door switch if a fuse blows soon after replacement, as a faulty switch can mimic fuse issues, leading to repeated failures.
Installation guidance
Power the appliance off and unplug it before handling any internal components. Verify the fuse’s dimensions (6×30 mm) and electrical rating match the original. Use proper safety gear and avoid touching live circuits. If in doubt, consult a professional technician to prevent hazard or further damage.
Tendodo: 20A 125V WB27X11138 Replacement Fuse Set
The Tendodo option provides a direct fit for a broad range of GE microwave ovens, including several JVM3160 series models. It emphasizes compatibility with WB27X11138 and similar numbers, ensuring a straightforward replacement path for many GE and Frigidaire units. The product listing highlights reliable protection against overcurrent and short circuits, maintaining consistent performance during busy kitchen cycles.
Model coverage and cautions
Before purchasing, confirm that your microwave uses the WB27X11138 form factor. The fuse is rated for 20A and 125V, making it suitable for high-power ovens. If your microwave is experiencing frequent fuse blows, consider checking other components such as the door interlock and high-voltage transformer for underlying faults.
QYKAVM: Microwave Fuse 8 Pack, 6mmx30mm 611 Type
This 8-pack from QYKAVM covers 20A, 125V, with six-by-thirty millimeter fuses designed to fit multiple GE and Frigidaire units. The listing notes broad compatibility and a caution not to force fit into a model that requires a different configuration. It also includes guidance to disconnect power completely before installation for safety.
Note: This option emphasizes compatibility with multiple microwave brands and a robust ceramic construction to withstand repeated cycles. It is suitable for technicians or households planning to stock up on spare fuses for routine replacements.
Practical considerations
Check the model numbers on your microwave and compare them to the listed replacements (WB27X11138, 5304509451, AP5648907, PS5136235, among others). Ensure the physical size, current rating, and voltage align with the original part. If you observe signs of arcing or burnt wiring near the fuse location, discontinue use and inspect the interior for damage.
FBULWSEC: 5 Pack 5304509451 Microwave Oven Fuse
This 5-pack provides a cost-effective way to replace common 5304509451 fuses used by Frigidaire and other brands. The set notes compatibility with model numbers such as 1810711, EA3486694, PS3486694, AH3486694, and AP4980426. It is paired with a reminder that if a fuse blows immediately after replacement, the door interlock switch could be the actual fault needing attention.
How to choose the right fuse
- Match the amperage: Most microwave fuses operate at 20A. Do not install a higher current rating than the original, which could fail to protect the circuit.
- Match the voltage: Use fuses rated for 125V in standard US household microwaves unless your model specifies a different voltage.
- Size and shape: The common 6 mm x 30 mm format is standard for many ovens; measure the existing fuse or consult your manual.
- Brand compatibility: Some fuses are marketed as universal, but always verify model compatibility and replacement numbers listed by the manufacturer.
- Check related components: If fuses blow after replacement, inspect the door switch, magnetron, transformer, and wiring for faults.
Buying Guide: Key Purchase Considerations
When shopping for microwave fuses, a balanced approach helps ensure safety, compatibility, and cost efficiency. Consider the following factors:
- Electrical rating: Ensure the fuse is rated for 20A and 125V, the most common specification for modern microwaves.
- Physical size: The standard 6×30 mm fuse fits many GE, Frigidaire, and Whirlpool units, but some models use different sizes. Verify the exact measurement before ordering.
- Replacement numbers: Many fuses have multiple replacement numbers (WB27X11138, 5304509451, AP5648907, PS5136235, etc.). Check your model’s parts list to match accurately.
- Quality and materials: Ceramic-bodied fuses tend to offer reliable durability and heat resistance compared to glass-bodied variants for some appliances.
- Safety guidance: Always unplug the microwave and discharge capacitors when working on high-voltage appliances. If you’re unsure, seek professional service.
- Bulk vs. single packs: If you frequently replace fuses, a multi-pack can reduce cost per fuse and reduce downtime due to stockouts.
In practice, selecting a fuse from a well-known replacement family with broad model coverage helps minimize compatibility issues. For households with multiple GE, Frigidaire, or Kenmore units, stocking a mix of 20A, 125V fuses in 6×30 mm format covers a wide range of models, while ensuring quick, safe replacements after surges or faults.
