How to Fix / Troubleshooting
Safety: Unplug the refrigerator before working behind the unit.
- Access condenser fan: Pull the refrigerator away from the wall. Remove the lower rear access panel to expose the condenser coil and fan.
- Clean area: Vacuum dust from the condenser coil and fan blades. Ensure nothing is blocking the fan.
- Check fan operation: With power restored briefly, observe if the fan runs when the compressor is on. If not, unplug again and continue.
- Test fan motor: Disconnect the fan and measure resistance. An open circuit indicates a failed motor.
- Inspect wiring: Check the connector and harness for damage or corrosion.
- Replace fan: Install a new LG-compatible condenser fan motor, secure wiring away from moving parts, reinstall the rear panel, and restore power.
Warning: Do not operate the refrigerator for extended periods with the rear panel removed; proper airflow is required for safe operation.
