1. Turn power off to the machine
2. Open the door, and remove all the stainless torx screws that hold the inner door to the outer door.
3. With a continuity tester, make sure the switches on the latch assy read as closed when the micro switch's are pressed in. Make sure you remove the wires off the switch's before you check them. There are only 2, one has white wires, and the other black wires.
If they both show closed, then order that panel. It is a very common problem with these, I must change 20 or more panels to 1 latch for no power calls.
