Description

This is the refrigerator main electronic control board that manages cooling cycles and user interface functions, restoring proper system control when the original board fails. It helps the appliance run normal defrost, compressor, and fan operations. What it does:

• Receives inputs from thermostat and sensors to control compressor and fans.
• Manages timed defrost cycles and heater operation when applicable.
• Controls interior lights, display, and user interface signals.
• Can resolve symptoms like no cooling, erratic compressor behavior, or unresponsive controls when board failure is confirmed.

What's included: One control board. Install notes:

• Power off and unplug the appliance before servicing to avoid shock.
• Handle the board by edges and avoid static discharge; use an anti-static wrist strap if available.
• Verify harness connectors match and fully seat; replace only if diagnosis indicates control board failure.
