Customer Questions and Answers for Main Power Control Board (Pcb Assembly) by Frigidaire

This is the refrigerator's electronic main control board. The power PCB coordinates the compressor, fans, and defrost system using sensor inputs—helping restore stable temperatures, proper defrosting, and consistent operation when the original board fails. What it does

• Routes and regulates power to the compressor and evaporator/condenser fans; failure can cause no-cool or intermittent cooling
• Interprets thermistor signals to manage run times and temperature targets; faults may lead to erratic temperatures
• Controls the automatic defrost cycle to prevent frost buildup and restricted airflow
• Interfaces with other control components; issues can present as clicking from the board, display anomalies, or unresponsive controls

• One main power control board

• Disconnect power at the breaker or unplug the appliance before servicing
• Use ESD protection; handle the board by the edges and avoid touching components
• Access the control behind the external service cover; transfer connectors one at a time and reuse original mounting hardware/enclosure
• Restore power and allow the refrigerator to stabilize at set temperatures after installation
