RFJZFRJ W19-8219E Refrigerator Main Control Board

The W19-8219E main control board serves as the central electronic control unit for specified Frigidaire refrigerator models. It monitors and regulates compressor runtime, evaporator fan operation, defrost heater activation, and temperature sensor inputs to maintain setpoint conditions. Constructed with surface-mount components on a multilayer PCB assembly, the board integrates power relays for high-current loads and low-voltage logic circuitry. It features multiple wire harness connectors for sensor feedback, user interface communication, and actuator control. Designed for 120V AC 60Hz household power supply.
