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

1. undefined: Reset unit and enter Test Mode 1 (push test button 1 time). 2. undefined: Measure condenser fan motor supply voltage at CON3 pins 4–1: expected 12V. If not 12V, replace Main PCB. 3. undefined: Check if condenser fan visibly rotates — if not, proceed. 4. undefined: Measure fan control signal voltage at CON3 pins 3–1: expected 0V < voltage < 5V. If not in range, replace Main PCB. 5. undefined: Measure fan feedback voltage at CON3 pins 3–1: expected 0V < voltage < 5V. If not in range, replace condenser fan motor. 6. undefined: Manually spin condenser fan — if sticky, replace condenser fan motor. 7. undefined: If all voltages and rotation are correct: explain to customer.
