Description

This Main PBA is the appliance's electronic control board that manages core functions and communication between sensors, user controls, and actuators—restoring normal control when the board is faulty. What it does:

• Hosts the appliance's main circuitry and firmware to control operation and timing.
• Processes inputs from buttons, displays, and sensors to run cycles and features.
• Restores power/control duties when a failed board causes unresponsiveness or erratic behavior.
• Common symptom linkage: unresponsive controls, display errors, random starts/stops, or complete lack of control panel function.

What's included:

• One Main PBA (PBA-M) assembly.

Install notes:

• Disconnect power to the appliance before servicing to prevent shock or damage.
• Handle the board by its edges and avoid static discharge; use an anti-static wrist strap if available.
• Verify connector seating and orientation; do not force connectors or bend PCB traces.
