Tumbles but no heat
Usual causes: Thermal fuse, heating element (electric), igniter or gas valve coils (gas), half-tripped breaker
A blown thermal fuse is often a symptom of a clogged vent, so replacing the fuse without clearing the vent means it will blow again.
Technician Takes two or three cycles to dry
Usual causes: Restricted vent, failing cycling thermostat, weak igniter
Start with the vent. If airflow is strong and it still takes too long, the heat source is cycling off too early.
Check first Won’t start at all
Usual causes: Door switch, thermal fuse, start switch, drive motor
On many models a blown thermal fuse stops the motor completely, so a dead dryer can still be a heat-related failure.
Technician Squealing or thumping
Usual causes: Idler pulley, drum rollers, drive belt, drum glides
A high squeal is typically the idler pulley. Rhythmic thumping is often a flat spot on a roller or a worn belt.
Technician Burning smell
Usual causes: Lint near the heater, a foreign object in the drum, motor overheating
Stop using the dryer. Lint buildup around the heating element or burner is a fire hazard.
Technician Stops mid-cycle
Usual causes: Overheating motor, moisture sensor, control board
A dryer that shuts off after 10 to 20 minutes and restarts once cooled is usually overheating, often from poor airflow.
