Dryer Not Spinning Only Humming

Quick answer

If your dryer is humming but not spinning, first check for overloading or obstructions. Ensure the drive belt is intact and the motor is functioning. If these checks don't resolve the issue, you may need to replace the motor or other components.

Confirm the symptom

• Dryer makes a humming noise but the drum doesn't move.
• Dryer turns on but doesn't start the drying cycle.
• No error codes displayed on the control panel.
• Dryer is properly plugged in and receiving power.
• No unusual burning smells or visible damage.

Tools and prep

• Screwdriver (Phillips and flathead)
• Pliers
• Multimeter
• Flashlight
• New drive belt (if needed)
• Work gloves
• Unplug the dryer from the power source before starting any repairs.
• Ensure the dryer is empty and cool to the touch.

Step-by-step troubleshooting

1. Check for Overloading
   Do: Open the dryer door and remove any items inside.
   Observe: See if the dryer spins freely by hand.
   Means: The drum should turn easily if not overloaded.
   Next: If the drum spins freely, proceed to the next step. If not, remove items and try again.
2. Inspect the Drive Belt
   Do: Unplug the dryer and remove the back panel.
   Observe: Check if the drive belt is broken or worn out.
   Means: A broken belt will not allow the drum to spin.
   Next: If the belt is damaged, replace it with a new one. If it's intact, proceed to the next step.
3. Test the Motor
   Do: Use a multimeter to check the motor for continuity.
   Observe: Follow the multimeter instructions to test the motor windings.
   Means: No continuity indicates a faulty motor.
   Next: If the motor is faulty, replace it. If it's working, proceed to the next step.
4. Check the Idler Pulley
   Do: Inspect the idler pulley for any signs of wear or damage.
   Observe: The pulley should spin freely and smoothly.
   Means: A worn-out pulley can cause the dryer to hum but not spin.
   Next: If the pulley is damaged, replace it. If it's fine, proceed to the next step.
5. Examine the Drum Rollers
   Do: Check the drum rollers for any signs of wear or damage.
   Observe: The rollers should spin freely and smoothly.
   Means: Worn-out rollers can cause the dryer to hum but not spin.
   Next: If the rollers are damaged, replace them. If they're fine, proceed to the next step.
6. Inspect the Motor Coupler
   Do: Locate the motor coupler and check for any signs of damage.
   Observe: The coupler should be intact and not broken.
   Means: A broken coupler can prevent the dryer from spinning.
   Next: If the coupler is damaged, replace it. If it's fine, consider other potential issues.

Common causes

Parts matching

To fix a dryer that hums but doesn't spin, you may need to replace one of the following parts.

• Drive belt: A rubber belt that turns the dryer drum.
• Motor: The component that powers the dryer's drum and blower.
• Idler pulley: A pulley that guides the drive belt and keeps it taut.
• Drum rollers: Rollers that support the dryer drum and allow it to spin freely.
