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.

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 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.

Microwave would turn on and count down, but not heating and not rotate turntable. Pressing door up would occasionally start heat.

First I disconnected the power and opened the door. Then I removed the top screws holding the top vent louvers, then removed the screw at the top of the touch pad. The touch pad removes by sliding up slightly then tilting top out. I unscrewed two screws holding the door latch assembly. Press the tab to remove and replace switch. Reco nnect wires, reseat latch mount by placing top bracket tab in place first, allign and secure with screws. Reseat touch pad by placing bottom tabs in first, tilt forward and press up to seat top tabs, secure with top screw. Secure vent louver screws, plug in and watch your microwave work again.
