What is this symptom?
Is your Whirlpool dryer running continuously without stopping at the end of the cycle? This issue often indicates a faulty cycling thermostat, timer malfunction, or airflow restrictions due to clogged vents. Understanding the causes can help you address this frustrating situation effectively.
Possible Causes
Faulty cycling thermostat
How to Identify: Dryer continues running beyond expected drying time; thermostat fails to sense correct temperature.
Part: Cycling thermostat
Timer or control board/timer malfunction
How to Identify: Cycle time does not advance; dryer never reaches end-of-cycle; control board shows damage or stuck relay.
Part: Timer or Main control board
Faulty door switch
How to Identify: Dryer behaves as if door is open, door not securely latching.
Part: Door switch
Clogged vent/exhaust or airflow restriction

User Suggested Solutions
-
Check and replace the thermostat if faulty. First, unplug the dryer. Locate the thermostat, usually found near the heating element. Test it with a multimeter for continuity. If there's no continuity, replace it with a new one.
-
Inspect the venting system for blockages. Disconnect the vent hose and check for lint buildup. Clean the venting thoroughly and ensure it's not kinked or crushed. Reconnect and test the dryer.
-
Test the compressor relay and control board. Unplug the dryer and access the control panel. Use a multimeter to check for proper function. If either component is defective, replace it with a compatible part.
