"Replaced all microswitches. Works great now.

"Customer complaint is, Microwave is sparking and has burning smell. Inspected and tested. Microwave is running, but not heating. Found the magnetron is black at the connector. Needs a new magnetron. This is a convection microwave, so Im going to need help when I go back. Also the tile backsplash is tight to the microwave on the back and could be a little tricky to remove and reinstall. I advised customer about the tile and warned her that it could be a problem. Please schedule with a second guy. I ordered a new magnetron, capacitor and diode from Marcone and should have it by October 2nd. Its Marcone, so I probably wouldnt schedule it before next Thursday. Please schedule me extra time. ; ordrd 1 10001590 (Magnetron) and 1 00625682 (Diode) and 1 00631397 (Capacitor)"

"They were opening the door and it popped the breaker again. I plugged it into another outlet, power came on, I hit open and it tripped the breaker. We reset the outlet. I took all connectors off of the door switches. Tested all switches. All test good. Tightened up the connections on all the switches. Tested the door six times. Ran it with a glass of water, and the water heated, and it ran great. I then opened the door and closed it a few more times, and it worked great. Fuse did blow when i first got here. I used one of our 20 amp fuses.

The customer said the microwave will randomly trip the breaker when its not beeping used. We checked the door switches and they tested good. I reset the breaker and the microwave is working properly. I gave the customer a quote for replacing the boards but advised it may not fix the issue. I advised her to have an electrician replace the circuit breaker.

Removed unit from the wall. Disassembled unit. Installed new magnetron from last diagnosis. Once installed tested 3 times to make sure it was working properly. Unit sounds and heating properly. Reassembled unit. Installed back into the cabinet. Tested again and is heating properly.
