How many drum support rollers does a dryer usually have?

Most dryers have two or four drum support rollers, typically located at the front and/or rear of the drum. It is often recommended to replace all rollers at once, even if only one appears faulty, to ensure even wear and prevent future issues.

What causes drum support rollers to wear out?

Over time, the constant rotation and weight of the dryer drum cause friction and wear on the rollers. Overloading the dryer, a worn drum belt, or prolonged use can also contribute to premature roller failure and breakdown of the roller material.

Can I use a dryer with a bad drum support roller?

It is not recommended to use a dryer with a bad drum support roller. Continued use can lead to further damage to the drum itself, the motor, the drive belt, or other internal components, potentially causing more expensive and extensive repairs.
