Parts for Whirlpool WMH78019HB2: Control Panel Parts

This electronic control board is the appliance's main circuit board that manages cycles, timing and user interface functions so the unit responds correctly to settings and commands. Use when control functions are intermittent or unresponsive. What it does:

• Regulates and sequences cycles, timers and electronic functions
• Processes user inputs from the control panel and front display
• Controls power to motors, valves and other components through relay outputs
• Helps prevent erratic or unexpected operation caused by a failed control board
• Commonly linked to symptoms like unresponsive controls, incorrect cycle behavior, error codes or a blank/garbled display

• Disconnect power (unplug or disconnect breaker) before beginning any service
• Handle the board carefully; avoid touching components and use anti-static precautions if available
• Some models require removal of the top or control console to access the board; review the model-specific service manual
