Dryer Not Spinning Properly

A tumble dryer that hums and gets warm but refuses to spin has suffered a mechanical failure in the drive system. Without the drum turning, clothes will not dry, and the concentrated heat poses a risk of scorching the stationary fabric.

How Dryer Drum Mechanics Work

The motor drives a long rubber belt that wraps entirely around the outside of the drum. As the motor turns, the belt grips and spins the drum. The drum is supported by bearings or small jockey wheels (rollers). If the belt snaps, or the rollers seize, the drum cannot turn.

Common causes

  • Snapped or stretched rubber drive belt
  • Motor failure or failed motor start capacitor
  • Seized drum support rollers or front bearings
  • Load too heavy, preventing the motor from starting the turn
  • Broken belt tensioner pulley

Safety warning

Always unplug the dryer before attempting to inspect it. The internal motor start capacitor can hold a lethal electrical charge even when the machine is turned off at the dial.

When to stop and call a professional

If the drum spins freely by hand (indicating a snapped belt) or is completely seized and impossible to turn, you will need an engineer to dismantle the dryer cabinet and replace the drive components.

Frequently asked questions

Why is the drum hard to turn by hand?

If the belt is intact, there will be some resistance from the motor. However, if it is completely stiff or grinds, the support rollers or bearings have seized.

How do I know if the belt is broken?

The easiest test is spinning the empty drum by hand. A drum with an intact belt has a heavy, smooth resistance. A drum with a snapped belt spins freely like a bicycle wheel.

What is a start capacitor?

It is an electrical component that gives the motor a massive jolt of power to start turning the heavy drum. If it fails, the motor will just hum and get hot.
