Possible Causes
Dry or worn idler pulley bearing, Worn drum support rollers, Misaligned belt causing edge wear, Foreign object in pulley area
How to Fix / Troubleshooting
Safety first: Disconnect power before opening the dryer cabinet.
- Localize the noise: Run the dryer briefly with panels on to identify the noise area (front, rear, base). Then unplug and disassemble accordingly.
- Inspect idler pulley: Access the belt tensioner (idler pulley). Spin it by hand; if it squeaks, grinds, or feels rough, replace the idler pulley assembly.
- Check drum rollers: Spin each roller. Replace any that squeal or feel rough.
- Remove debris: Clear any lint or foreign objects wrapped around pulleys or shafts.
- Reassemble: Refit the belt and panels, then test. Avoid using oil on sealed bearings; use only manufacturer-approved parts.
