How often should a dryer drum belt be replaced?

Dryer drum belts typically last for several years, often the lifespan of the appliance. Replacement is usually only necessary when the belt breaks or shows signs of severe wear, such as cracking or fraying, leading to performance issues.

Can I use my dryer if the drum belt is broken?

No, if the drum belt is broken, the dryer drum will not spin. While the motor may run and heat may be generated, clothes will not tumble, and therefore will not dry properly. Using the dryer with a broken belt is ineffective and could potentially cause further issues.

What causes a dryer drum belt to break?

Common causes include normal wear and tear over time, overloading the dryer which puts excessive strain on the belt, a seized drum roller or idler pulley causing friction, or foreign objects getting caught in the mechanism. Regular maintenance can help extend its life.
