What Causes a Knocking Dryer?
1 . Worn Out Belt
A worn-out belt is one of the most common causes of a knocking dryer. Over time, the belt can become frayed or cracked, causing it to lose its grip on the drum. This results in a knocking noise as the belt slips and tries to maintain contact with the drum.
2 . Loose Drum Support Rollers
Another common cause of a knocking dryer is loose drum support rollers. These rollers hold up the weight of the drum and allow it to rotate smoothly during each cycle. If they become loose, they can cause the drum to wobble and create a knocking noise.
3 . Damaged Blower Wheel
The blower wheel is responsible for circulating air through the dryer. If it becomes damaged or clogged with debris, it can create a knocking noise as it struggles to rotate properly. This not only affects the performance of the dryer but also creates an annoying sound.
4 . Loose Lint Trap or Seal
The lint trap and seal help keep lint from getting into other parts of the dryer. However, if they become loose or damaged, lint can get trapped in places where it shouldn’t be, causing a knocking noise as the dryer operates.
12 Tips on How to Fix a Knocking Dryer
Now that we’ve identified some common causes of a knocking dryer, here are some tips on how to fix the issue and get your dryer running smoothly again.
1 . Check the Belt
If you suspect that a worn-out belt is causing the knocking noise, it’s important to check and replace it if needed. This can often be done by removing the front panel of the dryer and accessing the belt from there. Also, make sure to clean any debris or lint that may have accumulated.
2 . Tighten the Drum Support Rollers

3 . Clean or Replace the Blower Wheel
If a damaged blower wheel is causing the knocking noise, it’s essential to clean or replace it. This can usually be done by accessing the back of the dryer and removing any debris or buildup around the wheel. If it is beyond repair, a replacement can easily be found online or at a home improvement store.
4 . Tighten or Replace the Lint Trap and Seal
If a loose lint trap or seal is causing the knocking noise, check for any obvious signs of damage and tighten any loose parts. If it cannot be fixed, it may need to be replaced entirely to prevent further issues.
5 . Balance the Dryer
An s due to uneven weight distribution. To fix this, adjust the feet of the dryer until it is level on all sides. You can use a level tool to ensure accuracy.
6 . Check for Loose Objects

7 . Tighten Loose Screws
Over time, screws and bolts on a dryer can become loose due to vibrations. Check all visible screws and bolts and tighten them if needed to prevent any unnecessary knocking noises.
8 . Lubricate Moving Parts

9 . Replace Worn-Out Parts
In some cases, worn-out parts may need to be completely replaced to fix a knocking dryer. This could include belts, pulleys, bearings, or even the motor. It’s important to identify the root cause of the knocking noise to determine which parts need to be replaced.
10 . Clean Inside the Dryer
Built-up lint and debris inside the dryer can also contribute to knocking noises. Use a vacuum or lint brush to clean out any accumulated debris inside the drum and around other moving parts.
11 . Call a Professional
If you are not comfortable performing any of these tasks yourself, it’s always best to call a professional for help. They have the knowledge and experience needed to fix a knocking dryer safely and effectively.
12 . Regular Maintenance
Prevention is key when it comes to fixing and avoiding future issues with your dryer. Be sure to regularly clean and maintain your dryer, including checking for any signs of wear and tear on parts. This can help identify potential issues before they become bigger problems that require costly repairs.
