If your dryer is making a loud thumping noise, it’s a sign that something isn’t right. Ignoring it can lead to bigger problems, so here are the most common causes and how to fix them.

1. Uneven or Overloaded Load

Heavy or bulky items, like comforters or sneakers, can cause the drum to spin unevenly, creating a thumping sound. Try redistributing the load and see if the noise stops.

2. Worn Drum Rollers

Most dryers have support rollers that help the drum spin smoothly. Over time, they wear out and cause thumping or rumbling sounds. If the noise persists even with an empty drum, the rollers might need replacement.

3. Damaged Drum Belt

A worn-out or loose drum belt can cause irregular spinning, leading to thumping noises. Inspect the belt for fraying or slackness and replace it if necessary.

4. Faulty Blower Wheel

The blower wheel moves hot air through the dryer. If it’s loose or clogged with lint, it may cause a rhythmic thumping or rattling sound. Check for obstructions and tighten or replace the wheel if needed.

5. Worn Drum Seals

If the drum seals are damaged or deteriorated, they can cause a loud thumping noise as the drum rotates. Replacing the seals can restore smooth operation.
