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

This controller is the refrigerator's electronic brain, managing cooling and defrost operations to keep temperatures stable. Replacing a failed board restores reliable compressor, fan, and defrost control when cooling becomes erratic.

• Regulates compressor and evaporator fan operation to maintain set temperatures
• Manages the defrost cycle to prevent frost/ice buildup on the evaporator
• Coordinates inputs from sensors/switches for consistent, efficient cooling
• Common failure symptoms include poor or intermittent cooling, heavy frost on the back wall/evaporator, constant running or short-cycling, or failure to start

• Disconnect power before servicing and use ESD precautions when handling electronics
• Access the control location (typically in the control housing or rear compartment) and photograph wiring for reference
• Transfer connectors one at a time to the new board; ensure all plugs are fully seated and harnesses are routed safely
• Reassemble panels, restore power, and verify normal compressor/fan operation
