How do I fix error code E CF on a LG refrigerators?

1. undefined: Reset the unit. Enter Test Mode 1 (press test button 1 time). Check whether condenser fan is rotating. If fan rotates, go to step 4. 2. undefined: If fan does not rotate, go to step 3. 3. undefined: Check condenser fan motor for mechanical binding: rotate fan blade by hand. If blade feels sticky or binds, replace the fan motor. 4. undefined: Measure fan motor voltage at CON4, 24th Pin to 23rd Pin. Expected: 11.4–12.6 V. If not in range, replace the main PCB. 5. undefined: Measure fan feedback voltage at CON4, 22nd Pin to 23rd Pin. If voltage is 0 V or 5 V, replace the fan motor. 6. undefined: Measure fan PWM voltage at CON4, 21st Pin to 23rd Pin. If voltage is 0 V or 5 V, replace the main PCB. 7. undefined: If all checks pass, explain normal operation to customer.
