Restore Your Microwave Safely & Affordably with the Right Replacement Fuse
Is your microwave completely dead or not starting? A blown 20-amp fuse is one of the most common and fixable issues. Before you consider an expensive replacement or service call, try this simple, cost-effective DIY solution. Our 6-Pack of premium ceramic microwave fuses gives you the exact part you need to get your appliance running again, plus valuable spares for the future.
Understanding Your Microwave Fuse:
The fuse is a critical safety device located inside your microwave. It is designed to protect the more expensive and complex circuitry (like the magnetron and transformer) from damage caused by power surges or internal electrical faults. When it "blows," it breaks the circuit, shutting off power to prevent a hazard. Replacing it with a correctly rated fuse is essential for safe operation.
Key Features & Benefits:
Exact Electrical Match: Rated at 20 Amps, 250 Volts, the standard for most household countertop microwave ovens.
Correct Physical Size: Measures 6mm in diameter by 32mm in length (6x32mm), ensuring a perfect fit in the fuse holder.
Critical Slow-Blow Action: Unlike fast-acting fuses, this slow-blow (time-delay) type allows for the brief, high current draw when the microwave light, fan, and magnetron initially turn on, preventing nuisance blows while still providing overload protection.
Universal Fit: While directly replacing the common GE model WB27X10388, this fuse is used across many brands including Whirlpool, Kenmore, Hotpoint, and others. Always check the amperage and physical size of your failed fuse to confirm compatibility.
Important Installation Notes & Safety Warning:
⚠️ DISCLAIMER: Always exercise extreme caution when working with electrical appliances. If you are unsure about any step, consult a qualified technician.
ALWAYS unplug the microwave from the wall outlet before attempting any repair.
Access to the fuse typically requires removing the outer casing (check your owner's manual for specific instructions). The fuse holder is often located near where the power cord enters the unit.
Remove the old fuse and visually compare its size and printed ratings (A and V) to ensure they match this product.
Insert the new fuse securely into the fuse holder.
Reassemble the microwave, plug it back in, and test.
