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

1. undefined: Power cycle the unit and enter Test Mode 1 (press TEST button once on Main PCB). 2. undefined: Open the freezer door and check for airflow from the icing fan; if airflow present, go to step 5. 3. undefined: If no airflow, manually rotate the icing fan blade by hand. If sticky or seized, replace the icing fan motor. 4. undefined: If fan rotates freely, measure motor supply voltage at CON4 12th Pin to 11th Pin in Test Mode 1; expected 11.4 to 12.6V. 5. undefined: If motor supply voltage is absent, replace the Main PCB. 6. undefined: If supply voltage is correct, measure feedback voltage at CON4 10th Pin to 11th Pin; expected active signal (not fixed 0 or 5V). 7. undefined: If feedback voltage is fixed at 0V or 5V, replace the icing fan motor. 8. undefined: If feedback is correct, measure PWM voltage at CON4 9th Pin to 11th Pin; expected not fixed 0 or 5V. 9. undefined: If PWM is fixed 0V or 5V, replace the Main PCB. 10. undefined: If all voltages are correct, explain normal operation to customer.

How to Fix

1
Power cycle the unit and enter Test Mode 1 (press TEST button once on Main PCB).
2
Open the freezer door and check for airflow from the icing fan; if airflow present, go to step 5.
3
If no airflow, manually rotate the icing fan blade by hand. If sticky or seized, replace the icing fan motor.
4
If fan rotates freely, measure motor supply voltage at CON4 12th Pin to 11th Pin in Test Mode 1; expected 11.4 to 12.6V.
5
If motor supply voltage is absent, replace the Main PCB.
6
If supply voltage is correct, measure feedback voltage at CON4 10th Pin to 11th Pin; expected active signal (not fixed 0 or 5V).
7
If feedback voltage is fixed at 0V or 5V, replace the icing fan motor.
8
If feedback is correct, measure PWM voltage at CON4 9th Pin to 11th Pin; expected not fixed 0 or 5V.
9
If PWM is fixed 0V or 5V, replace the Main PCB.
10
If all voltages are correct, explain normal operation to customer.
