Question about Microwave Ovens
Not my machine. Was told it just quit. Found a blown fuse. Had no replacement so I used a thin copper wire. With nothing in the oven sounded like it was running. As I watched the fuse became red hot. After 10 seconds before it blew the breaker tripped on the main board. Several tries with same result. Checked the magnetron, transformer, turntable motor and fan. The first 2 gave identical ohm readings as 2 other used units I had on hand. The motors function normally. No shorts detected. I dont know how to check the capacitors
Wow, I've never heard of a microwave having a circuit breaker on the main board.
I would suggest that you test the capacitor and the high voltage transformer.
Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:
