Error Code Er CF
The Er CF code tells you the condenser fan motor is not running. This fan sits near the compressor at the bottom-rear of the unit. It pulls air across the condenser coils to dissipate heat. Without it, the compressor overheats and shuts down. Your refrigerator stops cooling entirely.
Common Causes
Burned-out condenser fan motor: The motor windings fail from years of continuous operation. The motor receives power but does not spin. This is the number one cause of Er CF.
Debris blocking the fan blade: Dust, pet hair, and small objects collect around the condenser fan area. A plastic bag, twist tie, or chunk of dust can jam the blade and stall the motor.
Loose or corroded wire connector: The connector at the condenser fan motor vibrates loose over time. Corrosion on the terminals creates an open circuit. The board sees no fan feedback and triggers Er CF.
Failed main control board relay: The relay on the main PCB that drives the condenser fan burns out. The motor is fine, but it receives no power. You hear the compressor run but never hear the condenser fan kick on.
DIY Troubleshooting
Unplug and access the condenser fan: Pull the refrigerator away from the wall. Unplug it. Remove the rear lower access panel by unscrewing the screws or releasing the clips. The condenser fan is mounted next to the compressor.
Clear any debris: Inspect the fan blade area for dust buildup, pet hair, or foreign objects. Use a vacuum with a crevice attachment to clean around the blade, motor, and condenser coils. Spin the blade by hand to confirm it rotates freely.
Check the wire connector: Disconnect and reconnect the fan motor's wire harness. Look for green corrosion or blackened pins on the connector. Clean corroded pins with electrical contact cleaner and a small brush. A damaged connector needs replacement.
Test the fan motor: Disconnect the motor's wire harness. Set a multimeter to the 200-ohm scale. Measure resistance across the motor terminals. Expect 50-200 ohms on a working motor. OL or zero means the motor is burned out. Order a replacement condenser fan motor for your specific LG model number.
Test for power at the connector: If the motor reads good, plug the refrigerator back in and use a multimeter set to AC volts to check for voltage at the fan motor connector while the compressor runs. You should see approximately 120V AC. No voltage means the main control board relay has failed and the board needs replacement.
Professional Repair
Call a technician if the motor tests bad, if there is no voltage at the connector, or if you are not comfortable testing live circuits. TruePro offers a $59 diagnostic fee that applies as a credit toward the repair bill. All repairs include a 90-day warranty on parts and labor under CA License #51112.
