Whirlpool Dryer Loud Banging - Causes & Fix

Whirlpool Dryer Loud Banging — What’s Happening

A loud banging or thumping noise in a Whirlpool dryer is not an error code. It is a symptom that something is hitting the drum or cabinet repeatedly during operation. This is a mechanical problem, not an electronic control fault.

If the noise sounds like a knock or rattle, loose items in clothing or the cabinet are a common cause. If it is a thump or pounding that repeats as the drum turns, drum support components like rollers or glides are more likely worn or failing.

Most Likely Causes

Worn drum support rollers Drum rollers develop flat spots, rough surfaces, or worn axles over time, creating a thumping or banging as the drum rotates.
Loose items in the drum or cabinet Coins, buttons, zippers, or small debris trapped in the drum, lint filter area, or blower housing can rattle or bang against metal surfaces.
Worn drum glides or felts Drum glides wear down and allow the drum to contact other surfaces, causing banging or scraping noises during rotation.
Failing idler pulley A worn idler pulley or its bearing can produce banging, thumping, or squealing as belt tension changes during drum rotation.
Damaged or misaligned drive belt A worn, cracked, or loose drive belt can slap against the drum or cabinet and create intermittent banging sounds.
Blower wheel obstruction or wobble The blower wheel can accumulate lint or debris, or develop wobble from a loose mounting, causing loud banging in the rear of the dryer.
Dryer not level An unlevel dryer increases vibration and wear on drum components, which can amplify banging and thumping during operation.

How to Diagnose and Fix

Unplug the dryer before any inspection or repair work.
Inspect the drum interior for coins, buttons, zippers, or other loose objects that may be striking the drum.
Check the lint filter opening and blower housing for trapped debris or foreign objects.
Remove the front or rear access panels (depending on model) to inspect drum rollers, glides, belt, idler pulley, and blower wheel.
Spin the drum by hand and listen or feel for roughness, binding, or thumping that indicates worn rollers or glides.
Inspect the drum support rollers and their axles for flat spots, cracking, wobble, or misalignment, and check the idler pulley for wear or noise.
Check the blower wheel for obstructions, wobble, or a loose mounting, and replace if it wobbles or is damaged.
Verify the dryer is level by checking all four leveling legs and adjust as needed to reduce vibration.

When to Call a Pro

Call a technician if you are not comfortable disassembling the dryer cabinet or working around moving parts. If you have replaced rollers, glides, and the idler pulley and the banging persists, internal motor or drum mounting issues may require professional diagnosis. Also call a pro if the blower wheel is difficult to access or if reassembly of panels and belt routing is unclear after your inspection.
