Microwave wouldn't turn on and found breaker been tripped and then microwave wouldn't turn on at all.
Read some instructions and easily found the fuse. Replaced it. Still didn't work. Took control panel off to check door switches. Nothing I read mentioned a second fuse. Tested and it to had blown. Ordered another one. Popped them in. Done.

Door close wasnt registering and the microwave wouldn't turn on.
I looked up a YouTube video of someone with a similar over the oven microwave. That helped me get into the area behind the control panel where the door switches are. I checked the springs and the cam rocker? The thing that actually hits the button on the switch when the door closes. They were in good condition so I assumed the door switch was bad. There are two so I just purchased one figuring (hoping) that only one was bad. And lo and behold only one was bad. Bing bam boom. Put it all back together and I'm set. Not too difficult. Took a week of work because it takes like 50 days to ship. My kitchen looked like a hurricane after image because of all the parts scattered everywhere.

The display kept asking me to close the door, even though the door was closed. The interior light stayed on.
I used a Google search to show how to access the area behind the front panel. There was a folded paper copy with a schematic and wiring diagram in that space.Then I used a multi-meter to determine which of the THREE micro-switches was causing the problem. I called your help line and ordered a replacement switch. The switch was delayed in transit so your agent credited me with the cost of shipping.

When the part arrived, it had three terminals instead of two as shown in the on-line picture but that did not cause any difficulty in using it. It took about 20 minutes to remove and replace the old switch.

All seems to be working well now.

Finding which of the THREE switches was the problem was the most difficult part of the repair. All three "clicked" but the defective one did not click as easily. It needed to be depressed more than the door latch can would provide. Old age?
