I have checked everything I can think of on this dryer. Booted into service mode, it displays 3 fault codes - inlet thermistor, moisture sensor, personality. Moisture sensor test indicates the correct voltage. Both the inlet and outlet thermistors removed, and tested at approx 118 kohms of resistance which is correct per schematic. Backup outlet and inlet thermometers removed and tested for continuity, pass. High limit thermostat also removed and tested for continuity, pass. Door switch removed and tested, operational - continuity on outer two terminals when not depressed, continuity on outer and inner terminal when pressed, no continuity to outer two terminals when pressed. Heating coil removed and tested for continuity, pass. Any other ideas? Is it a control board issue?
