I replaced the door switch # AP2042622 becasue the machine just stopped turning on with no prior warning signs whatsoever. I found the old door switch stuck in the depressed position and could get it to pop out but it it was very sticky, so i thought the switch was the problem. New switch, machine still won't start. Having the main circuit 240V checked by an elxctrician friend tonight but the circuit doesn't act strange, no sign of pop or burn etc. I wondered if the fact that the new switch had an extra contact, slightly wider than the power contacts, that I didnot connect could be an issue. I'm thinking perhaps it could be a ground contact but there was no ground for the old switch.
