Whirlpool Appliance Control Unit (ACU) / Washer Electronic Control Board W11544680

Whirlpool appliance control unit/electronic control board that manages washer functions including cycle selection, filling, washing, draining, and spinning.

Is This the Right Part?

Common Symptoms

• Controls/display may be unresponsive.
• A selected cycle may not start or proceed normally.
• Washer functions controlled by the ACU—such as filling, washing, draining, or spinning—may not be commanded correctly.

Check Before Replacing

• Verify the washer is plugged in and the household circuit breaker is not tripped before diagnosing the ACU.
• Use the model-specific technical information to check stored diagnostic information and perform the specified HMI and ACU checks; do not diagnose the board from a symptom alone.
• With power disconnected, inspect ACU and user-interface harness connectors for full seating and visible damage.
• For qualified service diagnosis, assess the ACU status LED as directed by Whirlpool: after power-up it should transition to a slow blink; a normally slow-blinking LED indicates the ACU is probably OK and the fault may be elsewhere.
