Description

This main power control board (PCB assembly) is the appliance's electronic brain. It manages power and coordinates components so the unit starts, runs, and responds to commands correctly when the original board fails.

• Routes incoming power to internal components as needed
• Interprets inputs from the user interface and sensors to control operations and timing
• Oversees safety checks and protective shutdowns
• Typical failure symptoms: no power, won't start, unresponsive controls, intermittent shutdowns, or error codes

Includes: 1 main control board (PCB assembly). Installation notes:

• Disconnect power to the appliance before servicing to prevent electrical shock
• Use ESD protection and handle the board by the edges only
• Label or photograph connectors and transfer wiring one at a time to the new board
• Some models require service-mode setup or calibration after installation; follow the service documentation
