This main control PWB is the appliance's primary electronic control board that manages user inputs and cycle functions, restoring normal control when a faulty board causes operational issues. What it does:
- Receives user commands and runs appliance control algorithms
- Powers and updates the touchpad/display and indicator lights
- Manages timing, relay switching, and communication with sensors
- Common symptom: appliance won't start, has a blank or erratic display, or shows control-related error codes
- Helps correct unresponsive buttons, intermittent operation, or unexpected cycle behavior when board failure is confirmed
What's included: One main control printed wiring board (PWB), as pictured and specified by the manufacturer. Install notes:
- Disconnect power (unplug or shut off breaker) before accessing the control board
- Handle the PWB by its edges and avoid static discharge; use ESD protection if available
- Refer to the appliance wiring diagram and service manual for proper connector placement and safety procedures
