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.

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 bulb was burnt out

It is easy to repair the burnt out bulb if one has the correct bulb. Your website is very user friendly and your service is great. I was not able to replace the bulb at this time because our RV is at the repair shop for some other matters. I am sure the installation of the new bulb will go smoothly. Thanks for asking.

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.

When door was opened, the microwave would turn on.

Looked on line and found a you tube that said to check the door micro switches (there are three of them. Found one of the switches had an actuator that was stuck down. I got the actuator working but problem was still present. Another you tube showed how to repair the contacts in the switch and that solved the problem. however the plastic piece that holds the switches was broken and would not hold the switches securely. Ordered that piece and a new switch. Remove the vent plate on top (one phillips) and the control panel (one phillips). The switch holder is held in place with 2 phillips and is a little tricky to get it out and undo the wires. Once out, it's just a matter of putting the switches into the new holder and reinstalling it. Google the model number and the problem and there's virtually a you tube to repair ANYTHING.
