F12 is displayed and the refrigerator may not cool, with the condenser fan not running.

Safety: Unplug the refrigerator before accessing the rear compartment. The condenser fan is near live electrical parts and hot components.

Steps:

• 1. Access condenser fan: Remove the rear lower cover to expose the compressor and condenser fan assembly.
• 2. Clean and inspect: Vacuum dust from the condenser coils and fan area. Check for objects blocking the fan blades.
• 3. Spin test: With power off, spin the fan by hand. If stiff or seized, the motor is likely bad and should be replaced.
• 4. Electrical test: Disconnect the fan connector and measure motor resistance. An open circuit indicates a failed motor. Inspect wiring for damage.
• 5. Voltage check: If the motor tests good, verify that the control board is sending voltage to the fan when the compressor is running (only if you are trained to work with live circuits). If no voltage, suspect the main control board.

Note: Proper condenser airflow is critical; always reinstall the rear cover after repair to maintain correct air paths.
