Common Causes & Diagnosis
Blown Thermal Fuse
The thermal fuse is a one-time safety device that blows if the dryer overheats. Once blown, the dryer tumbles but produces no heat. Usually caused by a clogged vent.
Faulty Heating Element (Electric)
The heating element coil heats the air in electric dryers. When it breaks, no heat is produced. Visually inspect for a broken coil.
Faulty Igniter (Gas)
Gas dryers use an igniter to ignite the burner. A failed igniter means gas never lights and no heat is produced.
Defective High-Limit Thermostat
The high-limit thermostat monitors maximum drum temperature. If it fails open, it cuts heat even when temperatures are normal.
Clogged Vent / Exhaust Duct
A clogged dryer vent restricts airflow, causing overheating and blowing the thermal fuse. Clean the vent annually to prevent recurring issues.
