Parts for Whirlpool WMH54521JZ0: Control Panel Parts

This ACU box is the refrigerator control module that manages dispensing, ice/water functions, and user-interface signals to restore normal operation of the appliance. Replaces a failed or intermittent control module to get systems responding again. What it does:

• Acts as the main dispenser/door electronics control module, coordinating inputs from buttons and sensors
• Controls ice and water dispense sequences and related interface lights
• Can resolve faults like unresponsive controls, intermittent dispenser function, or erratic behavior tied to the dispenser electronics
• Works with the dispenser/door harness and related sensors to relay commands to the compressor and valves

• Disconnect power to the appliance before starting; perform repairs with unit unplugged or breaker off
• Handle the module carefully; avoid static discharge and rough handling of connectors
• Installation typically requires removing the dispenser/door access panel and disconnecting the harness; follow OEM service instructions
