✅ Cross Reference Information

Common Symptoms

• Squealing, squeaking, or grinding from the belt-drive area
• Drum fails to tumble or rotates inconsistently
• Drive belt slips or loses proper tension
• Visible wear, damage, or binding at the idler wheel
• Vibration associated with irregular belt tracking

Check Before Replacing

• Disconnect electrical power before inspection.
• With the dryer safely accessible and the belt unloaded as specified by the model’s service documentation, check whether the idler wheel rotates freely without binding or roughness.
• Inspect the idler wheel, lever, shaft, washer, retaining ring, and belt-contact area for visible wear, cracking, deformation, or displacement.
• Check that the drive belt is routed correctly and remains seated on the idler wheel; do not assume the idler assembly is the cause without checking the belt and other drum-support components.
• Stop inspection and consult the model-specific service documentation if access requires removing panels or releasing belt tension.
