Possible Causes
Failed dryer drive motor, Broken or slipped dryer belt, Jammed blower wheel, Faulty motor relay on control board
How to Fix / Troubleshooting
Safety first: Disconnect power before removing rear or front panels.
Steps:
- Check drum movement: With the door open, try rotating the drum by hand. It should move smoothly. If it is very stiff or jammed, there may be an obstruction.
- Listen for motor: Start a dry cycle and listen. A humming sound without drum movement suggests a seized motor or broken belt.
- Inspect belt and motor: Remove the rear or front access panel to view the dryer drive belt and dryer motor. Replace a broken belt; clear any obstructions at the blower wheel.
When to call a technician: If the motor is receiving power but not turning, or if you are not comfortable replacing belts, contact a service technician.
