Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Washer is completely unresponsive despite confirmed incoming power
• Washer stops mid-cycle
• Washer does not fill, drain, spin, or agitate as commanded
• Washer controls do not respond
• Washer displays communication or control-related error codes
• Visible burn marks or a burning odor from the control area

Check Before Replacing

• Confirm the washer is receiving power at the receptacle and that the circuit breaker or fuse has not tripped.
• Unplug the washer before inspecting the control area, wiring harnesses, and connectors for loose, damaged, corroded, or visibly overheated connections.
• Check the washer’s model-specific tech sheet and run its approved service-diagnostic routine if available; record any stored error codes before replacing the control.
• If the board shows burn damage or a burning odor, disconnect power and have the control and related wiring evaluated rather than assuming the board is the sole cause.
• Do not perform live-voltage measurements unless qualified to work safely around energized appliance circuits; manufacturer guidance indicates such testing may require a certified technician.
