Problems You May Notice

    • Dryer runs but produces no heat or insufficient heat • Clothes remain wet or damp after a complete cycle • Error code 20 displays on the digital control panel • Dryer stops mid-cycle unexpectedly • Tumbler continues to rotate but without heat • Prolonged drying times for normal loads
🔧

Possible Causes

    • Faulty thermal fuse that has blown or disconnected • Defective heating element with broken coils or poor electrical connection • Malfunctioning temperature sensor or thermistor providing incorrect readings • Airflow obstruction preventing adequate ventilation and heat distribution • Clogged lint filter restricting airflow and triggering safety shutoff • Blocked exhaust vent hose reducing air circulation • Door latch switch not properly engaging, disrupting heating circuits • Control board malfunction preventing power delivery to heating components • Moisture sensor failure causing premature cycle termination
✅

Safety Checks You Can Do

    • Remove and thoroughly clean the lint filter with a soft brush to ensure maximum airflow • Inspect the exterior exhaust vent for blockages, lint accumulation, or damage and clear as needed • Check the entire vent hose from the back of the dryer to the wall outlet for kinks, pinches, or debris; straighten any bent sections • Close the dryer door firmly and listen for a distinct click indicating proper latch engagement • Verify you have selected the correct drying cycle appropriate for your load type • Power down the dryer completely by unplugging it from the electrical outlet for 60 seconds, then plug back in to reset the system • Run a test cycle on a small load of damp items to see if the error clears • Check that the dryer is level and properly positioned away from walls to maintain adequate ventilation space • Ensure the room temperature is within normal operating range (above 50°F for optimal performance)
