A loud screeching sound from your dryer could be caused by a few different issues. Here are a few things you can check:
- Belt: A worn or broken belt can cause a loud screeching sound. To check this, unplug the dryer and remove the front panel. Look for any signs of wear or damage to the belt. If it looks worn or broken, you'll need to replace it.
- Drum Rollers: Dryer drum rollers can also cause a loud screeching noise. You can check this by turning the drum by hand. If it feels rough or wobbles, the rollers may be worn and need to be replaced.
- Idler Pulley: A faulty idler pulley can cause a screeching noise. You can check this by removing the belt and spinning the pulley by hand. If it feels rough or wobbles, it may need to be replaced.
- Motor: A motor that is failing can also cause a loud screeching noise. You can check this by turning the drum by hand and listening for any unusual sounds coming from the motor.
If you're not comfortable checking these components yourself, it's best to call a professional to diagnose and repair the issue.
