Exhaust thermistor failure

Check/Repair

Unplug the dryer and check the exhaust thermistor wiring. Reconnect any loose wires or replace the wire harness if damaged. Check the resistance of the exhaust thermistor using a multimeter. You should measure about 10,000 ohms at room temperature. If not then replace the thermistor because it's defective. Replace the main control board if the exhaust thermistor and wiring are okay.

Possible parts
Exhaust thermistor, Wire harness, Main control board

Door switch error

Check/Repair

Check the operation of the door switch using the diagnostic test mode, which is explained in the tech sheet that's typically stored in the console of the dryer. Replace the door switch if it doesn't work.
