FAQ

These 20A 250V slow-blow fuses are universal replacements compatible with a wide range of microwave brands, including GE, Whirlpool, Kenmore, KitchenAid, Jenn-Air, Amana, Magic Chef, LG, and Frigidaire. They are designed to replace OEM part WB27X10388.
This is a standard 6.35mm x 30mm (approximately 1/4 inch x 1 1/4 inch) ceramic tube fuse.
If your microwave has no power, the display is completely blank, or it fails to heat despite the light and turntable turning on, the main power fuse may have blown. A blown fuse is a safety mechanism that trips when there is a power surge or a short circuit within the microwave's internal components.
A fuse typically blows due to an electrical surge, a faulty door switch, or a short circuit in a high-voltage component like the magnetron, high-voltage capacitor, or high-voltage diode. If the new fuse blows immediately upon installation, it is likely that one of these internal components is defective and requires further testing.
Replacing the fuse is generally a straightforward task that takes about 15 to 30 minutes. You will typically need a screwdriver to remove the microwave's outer casing. Always ensure the microwave is unplugged from the power source before beginning, and exercise extreme caution as high-voltage capacitors can retain a lethal electrical charge even after the unit is unplugged.
