Customer Questions and Answers for Electronic Control Board (Pc Board) by Frigidaire

Electronic control board that manages a refrigerator's cooling, defrost and user-interface functions, restoring responsive controls and proper cycling when a failed system control causes erratic operation. What it does

• Regulates compressor, fans and relay switching to manage cooling cycles — failure can cause warm interior or continuous running.
• Controls defrost timing and heater operation to prevent frost buildup and excessive ice.
• Powers and communicates with the display and user controls — faults can cause blank or unresponsive controls.
• Monitors sensor inputs and coordinates system responses to maintain set temperatures.

• Disconnect power to the appliance before servicing to avoid shock or equipment damage.
• Handle the board by its edges and avoid static discharge — use anti-static precautions if available.
• Secure all connectors and mounting hardware, then power up and confirm normal operation and proper temperature cycling.
