Description

This main PCB assembly is the appliance's central electronic control board. It manages power distribution and coordinates signals between the user interface, sensors, and components to restore consistent operation when the original board fails.

• Distributes incoming power and supplies low-voltage control to the appliance's systems
• Interprets inputs from sensors/switches and executes programmed logic
• Drives outputs (e.g., motors, fans, heaters, valves, lights) via relays or triacs
• Supports diagnostics and fault monitoring
• Failures may show as no power, dead/unresponsive controls, intermittent shutoffs, or recurring control-related error codes after other causes are ruled out

What's included: 1 main PCB assembly Install notes:

• Disconnect power and allow capacitors to discharge before servicing
• Use ESD precautions; handle the board by its edges to avoid static damage
• Move connectors one at a time; release locking tabs and seat fully—do not pull on wires
• Inspect for shorted loads or damaged wiring before power-up; refer to service documentation for any required initialization or option coding
