Dryer makes a loud thumping or banging noise as the drum turns

Safety first: Disconnect power before working inside the dryer.

Step-by-step checks:

• Check load: First, run the dryer empty to see if the noise persists. Heavy items like shoes can cause banging.
• Inspect drum: With power off, rotate the drum by hand and listen for thumps. Check the drum seam for trapped objects.
• Access supports: Remove the front panel and drum. Inspect rollers for flat spots and replace as needed. Check the belt for wear and proper tension.
• Drum bearings: On models with rear drum bearings, inspect for wear or play. Replace bearing kit if loose or noisy.

When to call a technician: If the rear drum bearing or shaft is worn, professional replacement may be required.
