I have had the Sears service guy out here multiple times for this issue. He has replaced the ADC a couple of times, but cant seem to get the job done. Stopped the extened warranty. Why have it?
Any who.. Did the 3 cycle check...Nothin'. Went to unplug the Thermostat to check continuity while the unit was running & got bit between the heater & the cooling coil checking for heat. Measured 36VAC across the Heater element & thermostat wire pins on the feed side of the molex connector. Shorted element?
Thermostat continuity seems OK.
Serial is 21500421AV
Many Thanks O Noble One!
