Possible Causes

Faulty heating element (heater coil)

How to Identify: Dryer runs but no warm/hot air; multimeter shows no continuity on heating element terminals.

Blown thermal fuse or thermostat

How to Identify: Dryer tumbles but no heat; multimeter shows open circuit on thermal fuse or thermostat; sometimes accompanies overheating shutoff.

Part: Thermal fuse / thermostat

Clogged vent or airflow restriction

How to Identify: Dryer runs but warm air doesn’t flow properly; longer dry times; visible lint in filter or vent; overheating symptoms.

Part: Dryer vent/duct, lint filter

Control board or relay failure

How to Identify: Multimeter tests good on heating element and thermostats but no heat; error symptoms inconsistent with simple part failure.

Part: Main control board / heating relay
