How to Fix / Troubleshooting
Safety first: Unplug the dryer. Wear gloves to protect against sharp metal edges.
- Isolate the noise: Rotate the drum by hand with the dryer off and listen for squeals or grinding.
- Access drum supports: Remove the front panel and possibly the drum to expose the support rollers and idler pulley.
- Inspect rollers and idler: Spin each component. Replace any that squeal, wobble, or feel rough. Do not lubricate sealed bearings; replace them.
- Check felt seals: Inspect front and rear drum felt seals for wear or foreign objects. Remove debris and replace damaged seals.
- Reassemble and test: Refit the drum and panels, then run a test cycle to confirm the noise is resolved.
