Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Washer does not spin or agitates weakly
• Dryer drum does not turn
• Weak or failed drive operation
• Squealing or unusual belt-related noise
• Burning-rubber smell from belt slipping or wear
• Visible belt cracking, fraying, stretching, or rubber debris

Check Before Replacing

• Disconnect electrical power before inspection.
• With the appliance safely unpowered, inspect the accessible belt area for breakage, fraying, cracking, glazing, stretching, or rubber dust.
• If the drum or basket can be accessed safely, turn it by hand and note whether it rotates freely or unusually easily; excessive ease can be consistent with a broken or disengaged belt but is not conclusive.
• Check that the belt remains seated on the drive pulleys and is not visibly twisted or displaced.
• Inspect accessible pulleys for obvious binding, damage, or debris before replacing a belt; a seized or misaligned pulley can damage a replacement belt.
• Use the appliance model-specific service documentation to confirm belt routing and adjustment requirements.
