Oven showing door close error with _ _ M
there are little switches inside that the door hits when you close it. open both side panels then open and close the door. you'll see them in the upper left. there primary, secondary, and monitor. PSM. they either broke or something need adjusted. easy and cheap fix. you could take the leads off and jump them until you get switches. but they are a safety feature so do at your own risk.

did you check transformers. also k1 , k2, k3, relays. also make sure all wires are put back right and the diodes are going in the right direction.
