Mirowave hums when door is closed, fries switch when open
My microwave was tripping the breaker. I determined that the interlock switch wasn't being pressed properly. I added a small strip of duct tape to the door hook, and it started working. Then, a month or so later, it started tripping again. I traced it to the top door switch, so I replace it. The microwave would hum when the door open, then when I shut the door it trips the breaker again and fried the top door switch again. I tried removing the piece of tape and replace the newly fried switch, and it did the same thing. Any thoughts on what the issue could be? Thanks.

It is Kenmore Elite Model # 790.80373310. I also had the title backwards. It hummed when the door was closed and fried the switch when you opened the door.
