This ceramic microwave fuse is just over an inch in length. It is white in the center, and metal on both ends. This is a 20-amp fuse, and is used to power your microwave. If the touch pad on the microwave becomes unresponsive, the microwave produces little to no heat, or the appliance simply does not turn on, it could mean that your fuse is at fault and needs to be replaced. Because this part contains an electrical charge, remember to disconnect power to the microwave unit before you begin this repair.
NOTE: Before you start this repair, ensure that the microwave is unplugged, and the capacitor is discharged. A capacitor stores large amounts of electricity even after your microwave is unplugged.

Installation Instructions

Microwave completely stopped working
Turned out the issue was easily solved by replacing a single, inexpensive fuse.
First off, UNPLUG THE MICROWAVE.
The fuse is located under the plastic grill at the top of the microwave. It's held on by two screws. Once you've removed the screws and taken off the plastic grill, you go to the right side of the mic ... Read more rowave and remove another screw that holds a small metal grill in place. Removing the small metal grill is probably the toughest part of this repair. You kind of have to rock it back and forth a bit to get it to release. Once that's off, you can get to the fuse. I removed the burnt out one with a pair of needle nose pliers. I also put a small piece of cardboard under the fuse when I did this so I didn't accidentally drop it into the innards of the microwave. I did the same thing when I replaced the new fuse. I then plugged the appliance back in and made sure it worked. Once that was confirmed, I replaced both grills.

Electrical overload protection comes from this microwave time delay fuse, rated at 20 amps and 250 volts. It tolerates brief startup current while opening the circuit during a sustained overload or short circuit. A blown main fuse may leave the microwave without power or prevent it from starting. The fuse cannot be reset and requires replacement once it opens. Internal microwave components can retain a dangerous electrical charge after unplugging, so disconnecting the power cord alone does not make internal handling safe. This is an OEM part sourced directly from the manufacturer.

Loss of controls and no heat.
Assisted experienced and knowledgeable local repair shop technician. Had no issues during repairs. Microwave worked properly after repairs were completed.
To protect against a power surge or electrical fault, this OEM fuse assembly interrupts circuit power. Have a professional install it: high-voltage capacitors can retain a hazardous charge even after the appliance is unplugged.

Interrupt excess electrical current with this microwave fuse assembly. It acts as a safety link, opening the circuit when current rises above its rated limit to help protect connected components. A blown fuse may stop heating or other microwave functions. Replacing it restores the circuit after the cause of the failure has been corrected. Never bypass the fuse or use a different rating. Microwave components can hold a dangerous electrical charge even when unplugged, so internal access requires special safety precautions. This is an OEM part sourced directly from the manufacturer.
