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.

Customer Repair Stories

I diagnosed the problem incorrectly: based on a previous repair.

The old fuse is perfectly good. The new ones arrived within a day.

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 microwave 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 not heat food

First and most important - unplug AC power 24 hours before service.

I removed the vent cover above the main door, then I removed the screw which holds the control panel in place, unplugged the main connector on the control panel so I would have enough room to work, removed grounding screw from the DIODE ASSY, pulled connector off the CAPACITOR with pliers, installed new DIODE ASSY.

After installation of DIODE and the control Panel, I plugged in the AC power and allowed the CAPACITOR to charge - this takes about an hour or so, then test. Works perfect!

Micro was not producing heat.

Removed unit from above range. (A two person task.) Removed display panel, disconnecting wires from plugins. Removed outer cover to access magnetron. Used camera to take photos before disconnecting other wires. Replaced magnetron and reconnected wires, double checking with photo. Tested prior to reinstalling. It works fine.

This is the replacement monitor switch for your microwave. It is black in color and measures approximately 1 inch by ¾ of an inch. This switch monitors the door latch position of your microwave and communicates to the electronic control board whether the latch is open or closed. If the switch is damaged, your microwave may not start, even though the door latch is closed. You can check the continuity of the switch by using a multimeter. Be sure to disconnect the microwave from power before you begin this repair.

Customer Repair Stories

To heat a cup of coffee, user entered "10:00" instead of "1:00". Mess! After cleanup, microwave ran, but would not heat. While running, it made 2 or 3 time the noise volume as before.

I went for the cheap things first. Ohmmeter showed one of the thermostats in the magnetron compartment was open. I ordered and replaced all three thermostats. Still no heat. I took the unit off the wall (aaarrgh!) and checked the oven cavity thermal cutout. It said 7 ohms. I tested by shorting the wires together, but still no heat. So, I ordered the magnetron and diode cable. When replacing the diode cable (be sure to discharge the big cap!) either I broke it, or it was already damaged. It came off in two pieces. The new diode cable was re-enforced with thick heat shrink tubing, to prevent such breaking. You need a very short screwdriver to replace the magnetron. Now, all fixed! ~$150. A new one lists for $2000, installed in the overhead. My wife thinks I am a genius.
