FAQ

Can I use my dryer while it's making a squealing sound?

It's not recommended. The noise could indicate a serious issue that may worsen over time.

How often should I replace the dryer belt?

The dryer belt typically lasts 3-5 years, but this can vary based on usage and maintenance.

What if the squealing sound only happens when the dryer is first turned on?

This could indicate a lubrication issue or a problem with the motor. Check the moving parts for lubrication and ensure the motor is functioning correctly.
