Not sure if I should replace the cycling thermostat or moisture sensor board. The dryer heats and timer control advances only in time mode. Auto cycles heat but do not advance. Should I replace the cycling thermostat or moisture control board? Will either of the items help remedy the auto advance cycle? There is continuity on the old cycling thermostat but I am not sure quite how they function. Can it have continuity when cool and not function? Can you give me advice on how to proceed?
