✅ Cross Reference Information
Current Part NumberW11550453
Common Symptoms
- Washer will not start or the controls do not respond.
- Cycle stops mid-operation or does not advance normally.
- Washer does not properly command filling, draining, spinning, or agitation.
- Persistent error codes remain after power is reset and associated components are checked.
Check Before Replacing
- Confirm the washer is connected to a working outlet and that the household circuit has not tripped.
- Disconnect power before inspecting the control-unit area, then check that accessible wiring harness connectors are fully seated and show no obvious damage.
- Compare the installed board’s part number and connector layout with W11550453 before condemning the board.
- After restoring power, note whether the control panel responds and whether the washer can enter its manufacturer-specified diagnostic procedure.
- Do not use a control-board symptom alone as proof of failure; door-lock, wiring, power-supply, valve, pump, motor, sensor, or user-interface faults can produce similar symptoms.
Pro Tip
Before disconnecting the old board, document each harness location and connector orientation; a connector that is not fully seated can reproduce the original failure or create a new one.
