Finally got around to taking things apart. Boy do things get crusty over the years! The latch assembly was pretty crudded up in fact the lever that locks the door was frozen. Got things cleaned up and still everything appears to work except the clean function. Tested the micro switches and they all work and appear to be adjusted correctly. I did find the wiring schematic online and have attached. The overtemp switch shows continuity. I think it's narrowed down to the thermostat, the large relay in the back of the oven, or the timer board. As I stated before, I follow the steps to put oven into clean mode. Everything seems to go well (cooling fan goes on, lever can be moved to the lock position, timer can be set when to start and stop), but the clean light does not come on, nor does the oven heat. Schematic is a bit hard to follow, but I did verify the selector switch contacts, but couldn't decifer the thermostat. Also the only connection to the timer looks to be large wires going to E6 and E7. Any suggestions?
