How to Fix / Troubleshooting

Safety first: Unplug the dryer before internal inspection.

Step-by-step checks:

Inspect drum surface: Look for sticky or dark deposits on the drum. Clean with a non-abrasive cleaner and a soft cloth.
Check drum seals: Inspect front and rear felt seals for wear, tears, or grease contamination. Replace seals if damaged.
Inspect rollers and bearings: Look for grease or oil near the drum edges. Replace leaking or worn rollers and clean any residue.
Rust treatment: Light rust can be sanded and painted with high-temperature appliance paint. Deep rust may require drum replacement.

When to call a technician: If seals and supports need replacement and you are not comfortable removing the drum, seek professional service.
