Tumble Dryer Motor Not Running or Dead
A dryer that does nothing at all when started — no hum, no movement, no heat — points to a fault either in the motor itself or in the power path leading to it.
Common causes
- A tripped thermal overload switch built into the motor, which cuts power if the motor overheats
- A blown thermal fuse elsewhere in the circuit
- Worn motor brushes on brushed motor designs
- A seized motor bearing preventing the shaft from turning at all
- A failed start capacitor on capacitor-start motors, leaving the motor unable to begin rotating
How to check it
- Confirm power is reaching the dryer and that the door switch and start controls are functioning, ruling out non-motor causes first.
- With the dryer unplugged, try to rotate the motor shaft by hand (accessible once the belt is removed) — resistance suggests a seized bearing.
- Check the motor's thermal overload, often a small manual-reset button on the motor housing itself.
- Test the start capacitor, where fitted, with a multimeter capable of capacitance testing.
Fixing it
A tripped thermal overload sometimes resets itself once the motor cools, but repeated tripping signals an underlying problem like a seized bearing forcing the motor to work harder than it should. A failed capacitor is a direct, inexpensive swap. A seized motor bearing generally means the motor itself needs replacing, since these bearings aren't usually serviceable separately.
When to call a technician
Motor replacement involves handling wiring connections and sometimes recalibrating mounting brackets, and getting the wiring wrong can create a safety hazard — this is a repair worth having a professional handle unless you're confident reading your model's wiring diagram.
Prevention tips
Avoid restarting a dryer repeatedly after it trips on thermal overload without investigating why — repeated tripping is the motor's way of signaling it's working harder than it should, usually due to a seized bearing or pulley elsewhere in the drive system placing extra strain on it. Addressing the root mechanical cause protects the motor from a failure that's far more expensive to fix than the part that was actually straining it.
Quick questions
Can a dead motor be caused by something as simple as a stuck drum? Yes — if the drum is jammed by worn rollers or a foreign object, the motor can struggle to start and trip its thermal overload, mimicking the symptoms of a genuinely failed motor.
Is motor replacement usually worth the cost compared to a new dryer? It depends on the machine's age and overall condition — for a mid-life dryer that's otherwise in good shape, motor replacement is usually far cheaper than buying new.
Parts and repair notes
Motor repairs vary widely in cost and complexity depending on the actual cause — a failed capacitor is a quick, inexpensive fix, while full motor replacement is a larger job involving wiring and mounting work. Given the range of possible outcomes, it's worth having a technician diagnose the exact cause before assuming the worst, since many motor-related complaints turn out to be a smaller linked component rather than the motor itself.
Related issues to watch for
A motor that won't run is worth checking against the drum-not-tumbling section of this guide, since a jammed drum can present with very similar symptoms to a genuinely failed motor, and it's a much cheaper fix if the motor turns out to be fine.
