First off all, I would hope the microwave is on its own breaker, rated at 30A, since the microwave has a fuse rated at 20A.Normally if the high voltage capacitor is shorted, when you hit the "Start" pad to begin cooking, the fuse will blow instantly.If you have a problem with the monitor interlock switch, the oven will blow the breaker when the door is closed.But
not always, so it may be a shorted high voltage capacitor, but I would
first check for a shorted monitor interlock switch, as well as checking
the mounts for all three door switches.See my help file on door switches
here.
Here is a link you or someone you know can use to test the high voltage
capacitor, but read their safety warnings first:
