Common Symptoms

• Excessive idler-arm or shaft play when the belt is tensioned
• Worn, bent, cracked, or damaged arm or shaft
• Idler pulley does not rotate freely on the shaft
• Belt dust, fraying, or abnormal belt tracking associated with poor idler alignment

Check Before Replacing

• Unplug the dryer and allow heated components to cool before inspection.
• With the belt tension released, inspect the arm and shaft for bending, cracks, wear, or unusually loose movement.
• Check that the idler pulley wheel rotates freely on the shaft and that its washers or retaining hardware are present.
• Inspect the drive belt for fraying, edge damage, belt dust, or abnormal tracking before concluding the arm is faulty.
• Verify that the idler-arm spring remains attached at the arm and motor-bracket connection points.
