So this started a day or so ago. When I open the door after I microwave something the circulation fan turns on despite the magnetron is no longer nuking the food. I tested with a bowl of stuff in there that would have sizzle if the microwave is on and the door slightly open (me behind some metal plate to protect myself), and the food didn't sizzle, so the magnetron is not on when this happen.
I googled and it seems like the common consensus is the door interlock switch is worn or stuck, then someone also said it was a bad thermostat / thermal overrun or protection switch.
At about 8 years this thing seems to be doing ok, the only concern if I were to replace the whole thing instead of repairing these switches is: will the tile in the back align if I replace it, or will something stick out or cannot fit back in? I would rather repair these switches to save the trouble if the back splash didn't cover all the way up or other nonsense, or I have to cut different holes in the back to fit the vent, mounting, etc.
Your thought?
