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.

Microwave completely stopped working
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.

The secondary door switch is a simple on/off mechanism that stops the microwave from operating when the door is open (normally opened). The switch monitors the door latch position, and communicates whether the door is open or closed to the electrical control board. This door switch is approximately 1 inch long, and has 2 metal prongs called terminals that extend out of its body. Common symptoms related to a faulty secondary door switch include: microwave will not turn/shut off, or the microwave will not heat properly. NOTE: Before you begin this repair, first make sure your microwave is unplugged, and that your capacitor is discharged. A capacitor stores large amounts of electricity even when your microwave is unplugged.

Microwave Fan Turned on When Door Was Opened
If it is not obvious which switch is bad, in our case the bad switch felt "soft" when we pressed the switch button with our fingers. A good switch has a firm "click" when pressed.
The switches are easy to replace - pop out the old switch (no tools required) and pull off the electrical connectors. Then pop in the new switch and reattach the connectors.

Unplug your microwave before attempting this repair. You will need to remove the grill, which is held into place by two screws at the top of the grill (open your microwave door before doing this). Remove the grill. Remove the screw on the left holding the control panel in place. Loosen the screw behind the panel. You should now be able to lift the panel up and pull forward to detach. You will find the door switch by removing the screws to detach the switch assembly. Press on the release tab to remove the middle switch. Disconnect the wire connector to release the old switch. The door switch is normally closed.
