Here’s an answer I’ve not seen elsewhere: Over time the door latch wears down such that the timing of the interlock switches gets confused. There are three switches that must activate in the correct order. When the latch is worn, the timing of the two lower switches is disrupted. After trying everything else (and I mean EVERYTHING), I noticed the worn latch and started experimenting, opening and closing the door very slowly and listening for the switches to activate. They must be out of sync, somehow. How can I correct it? Believe it or not, I simply wrapped some duct tape around the tip of the lower black plastic latch. This caused one of the lower switches to activate a fraction of a second sooner . . . before the second switch . . . and the problem was solved.
