Description

This is the main control (power control) board assembly that manages a refrigerator's core functions and power distribution. Replacing a faulty board restores control of compressors, valves, lights and user interface signals. What it does:

• Interprets user inputs and runs control logic for cooling cycles and defrost.
• Helps stabilize operation; a failed board can cause intermittent operation or complete failure to start.
• Common symptom indicators: blank or unresponsive display, no cooling, erratic cycling, or persistent error codes.

What's included:

• One main control (power control) board assembly.

Install notes:

• Disconnect mains power before beginning any repair to avoid shock or damage.
• Handle the PCB by its edges and avoid contact with component leads; observe ESD precautions.
• Verify the part number on the existing board matches this replacement before installing.
