I've found it has to do with the door and the way the switches are engaged when door is closed. A firm bump upwards on the handle when closed, clears the short. But repeated opening and closing recreates the short (especially if any downward pressure is applied when closed or closing) so my problem is the sagging and how that effects the interlock switches. I can hook my continuity tester to the unplugged plug (hot and neutral) and when the meter reads continuity there's a short, which would blow the fuse if unit was connected to 120v. Problem is there's not a lot of adjustment in the switches, holder or door hook latch. I'm thinking maybe increase the hook spring pressure. It really is how the hooks hits the micro switches when downward pressure is on the opening side of door. Any thoughts?

There is a short in the door interlock or related wiring.
