A noisy dryer may sound like a loud bicycle. It can also mean there is something wrong inside it. This article will look at the common causes of a squeaking or thumping dryer. In some cases, the noise is due to a loose screw or a damaged blower wheel. In other cases, a damaged bearing may be the culprit. In either case, it’s best to have the noisy dryer checked by a qualified technician.
Loose screw causes squeaking noise in a dryer
A loose screw may be the cause of a squeaking noise in your dryer. It may occur because the door is flimsy or has been worn down. It may also occur because the drum bearing is worn out. To solve the problem, lubricate the hinges with WD-40 and tighten them. If the problem persists, consider replacing the motor.
The other likely culprit is a loose screw. Sometimes, a loose screw will cause the dryer to squeak. A loose screw can also cause the drum to tumble irregularly. This is similar to the sound of a bicycle’s tire trilling. It’s worth examining the motor to determine whether there is a loose screw. If there is no visible loose screw, try removing it with work gloves.
Faulty motor pulley
If your dryer is making a loud noise, it is possible that it has a faulty motor pulley. This is a component that is essential to the proper functioning of the dryer. It turns the drum, and a faulty motor pulley can cause increased noise during the spin cycle and possibly a broken motor. Here are some tips on how to troubleshoot a noisy dryer.
First, remove the drum. Next, unscrew the drum from the drive shaft. Use a 13/16 wrench to remove the drum. To access the motor, use an adjustable wrench to grip the flat part of the drive shaft. Once you’ve removed the drum, you can use the wrench to tighten the motor clamp. Make sure that the belt is completely untwisted before you remove the drum.
Damaged blower wheel
If your dryer is making a noise, it could be due to a damaged blower wheel. The blower wheel guides air through the dryer, pushing it out the exhaust vent. Sometimes lint can get stuck in the blower wheel, causing it to wobble and cause a loud noise. If the noise is coming from the blower wheel, the sleeve may be worn and will need to be replaced. You can also check the blower wheel’s hub for wear.
You can easily check the blower wheel by removing the cover and checking its integrity. It is screwed to the motor shaft with the left-hand threads. If you cannot locate the blower wheel, remove the motor clamps and tighten the wrench’s jaws. Once the blower wheel is free, turn the motor shaft with a pair of pump pliers to break it free.
Faulty motor pulley causes thumping noise in a dryer
If your dryer is making a loud thumping noise, it may be time to replace the motor pulley. This part of your dryer is responsible for the tumbling action and is easily replaced. If the noise persists, you should visit a qualified repairman to inspect the motor pulley. Faulty motor pulley causes thumping noise in a dryer is dangerous.
If the thumping noise continues, the drum bearing may be worn out and causing the drum to scrape the casing or spindle. If the drum support is not rolling, the bearing may be faulty. You may also notice scraping noises coming from the drum support. A drum bearing that has worn out may also be a source of rattling noise.
Other causes of squeaking noise in a dryer
If your dryer is making a squeaking noise, there may be a couple of possible causes. First, the belt is worn or damaged. If it is, you need to replace it. Second, it is possible the drum support is scraping against the element enclosure. Finally, it may be a worn motor. Thankfully, there are easy fixes for both problems.
A damaged idler pulley is another common cause of squeaking noise in tens of thousands of dryers. It connects the motor and belt, and when it wears down, it can break. To fix this, tighten the pulley with a screwdriver. If the squeaking sound continues, it may be time to replace the idler pulley.
