Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Washer basket does not spin or agitator does not move
• Slow or inadequate spinning, leaving clothes unusually wet
• Squealing or other belt-related noise during operation
• Burning-rubber odor near the motor or belt area
• Visible belt cracking, fraying, glazing, or breakage

Check Before Replacing

• Disconnect power before inspection.
• Using the model-specific service procedure, inspect the belt for breakage, fraying, cracking, glazing, or looseness on the pulleys.
• Check that the belt remains properly routed around the motor, pump, and transmission/drive pulleys where applicable to the washer design.
• With power disconnected, check whether the accessible pulleys rotate freely and whether the belt slips excessively; do not operate the washer with exposed moving parts.
• Confirm the belt part number and dimensions against the washer model before replacement, since similar symptoms can result from a failed pump, bearing, thrust assembly, motor, or transmission.
