Since I can't manually change the timer setting is there a way to test this controller (adaptive defrost timer)?

ANSWER Hello Jim. Test the heater and the thermostat. If good, and there is a defrost issue, replace the adaptive board 4388932 in the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
