Suddenly began having issues with microwave stopping in process with "Close Door" error message and also randomly having the light come on inside the microwave when no one was even near it (as if the door had been opened). Assuming this is a door switch issue, but not sure which one or where to locate the diagram for this model (Whirlpool MMV5208).

2nd issues - we unplugged the microwave due to the door issue and when we plugged it back in so that we could at least use the light over our stove, it immediately flipped the breaker. What am I looking at for an issue here and how would I address it? Any specific part recommendations and diagrams would be helpful!

Thanks!
