The belt wraps the drum and the motor pulley. It breaks with age or when the drum is overloaded, and the symptom is a motor that runs with a drum that does not turn.
Appliance part
Dryer Thermal Fuse
The thermal fuse is a one-shot safety device on the exhaust path.
It opens when the dryer overheats, which is why replacing it without clearing the lint blockage leads to a repeat failure
Test it for continuity before ordering.
Symptoms of a failed dryer thermal fuse
- Dryer runs but produces no heat
- Dryer is completely dead on the heat circuit
- Fuse fails again shortly after replacement
Fitment
Fuses are rated by temperature and mounting style. Match the model number and check the vent for restriction at the same time.
Before you buy
Confirm the model and serial plate before ordering — two parts can look identical and still not fit. If you would rather not fit it yourself, request a repair quote and we will route it to an independent technician.

The idler keeps tension on the belt. A worn pulley bearing produces a chirp or squeal that changes with drum speed, and a seized pulley will shred a new belt.
Electric dryer elements are coiled resistance wire in a metal frame. They break with age or heat cycling, and a broken coil is often visible as a gap or a blistered section.
The igniter is a ceramic element that glows to light the gas burner. It is fragile, and a cracked igniter will glow weakly or not at all while the dryer tumbles without heat.
The blower moves air through the drum and out the vent. A cracked hub or stripped center lets the wheel spin on the shaft, so the dryer runs quietly but airflow drops and clothes stay damp.
Rigid or semi-rigid duct, clamps and an exterior hood. Replacing crushed flex duct with smooth rigid pipe is often the real fix for long dry times — before any part is changed.
