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.
