Dryer is running but makes a loud banging or thumping noise, especially during start-up or with heavy loads.

Safety first: Unplug the dryer before removing any panels. Be cautious of sharp edges.

• Check load: Stop the dryer and redistribute the load. Very small or very heavy items can cause imbalance and banging.
• Inspect drum interior: Look for loose drum baffles (lifters) and tighten or replace if they move. Remove any foreign objects such as coins or buttons.
• Access drum supports: Remove the front or rear panel to access the drum rollers and rear bearing. Spin the drum by hand and listen for grinding or flat spots.
• Replace worn rollers/bearing: If rollers are worn, cracked, or noisy, replace them as a set. If the rear bearing is loose or noisy, replace the bearing kit and lubricate as specified.
• Inspect felt seals: Check front and rear drum felt seals for damage or detachment. Replace if worn to prevent metal-on-metal contact.
