Why Is My LG Dryer Making a Clunking Noise

Quick answer

A clunking noise in your LG dryer often comes from loose or worn parts inside the drum or motor area. Turn off the dryer, unplug it, and check for loose objects or damaged components. Replace worn parts like the drum rollers or motor if needed.

Confirm the symptom

• Noise occurs during the drying cycle
• Sound is a loud clunk or thud
• Happens when the drum is rotating
• Noise stops when the dryer is off

Tools and prep

• Screwdriver set
• Needle-nose pliers
• Flashlight
• Work gloves
• LG dryer manual
• Unplug the dryer before starting
• Clear work area for parts

Step-by-step troubleshooting

1. Check for Foreign Objects
   Do: Inspect the drum and lint trap for loose items like coins or small toys.
   Observe: Find and remove any objects causing the noise.
   Means: Foreign objects can create clunking sounds when the drum rotates.
   Next: If no objects are found, move to the next step.
2. Inspect Drum Rollers
   Do: Remove the front panel to access the drum rollers. Check for wear or looseness.
   Observe: Worn or loose rollers can cause the drum to hit the frame.
   Means: Drum rollers support the drum and reduce friction.
   Next: If rollers are damaged, replace them.
3. Check Drum Bearings
   Do: Spin the drum by hand and listen for grinding or resistance.
   Observe: Unusual resistance or grinding indicates worn bearings.
   Means: Worn bearings can cause the drum to wobble and make noise.
   Next: Replace drum bearings if necessary.
4. Examine Motor Mounts
   Do: Locate the motor and check the mounts for looseness or damage.
   Observe: Loose or broken mounts can cause the motor to shift during operation.
   Means: Motor movement can lead to clunking noises.
   Next: Tighten or replace motor mounts as needed.
5. Test Idler Pulley
   Do: Inspect the idler pulley for cracks or wobbling.
   Observe: A damaged idler pulley can cause belt misalignment and noise.
   Means: The idler pulley keeps the belt tensioned and aligned.
   Next: Replace the idler pulley if damaged.
6. Check Belt Tension
   Do: Inspect the dryer belt for proper tension and signs of wear.
   Observe: A loose or worn belt can cause the drum to rotate unevenly.
   Means: The belt drives the drum rotation.
   Next: Adjust or replace the belt if needed.
