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

1. undefined: Reset the unit and enter Test Mode 1 (press test button 1 time on Main PCB). 2. undefined: Open the freezer door and check air flow from the icing fan. If airflow is present (windy), go to step 4. 3. undefined: If no airflow, physically rotate the fan blade by hand. If blade feels sticky/seized, replace the icing fan motor. 4. undefined: Measure fan motor supply voltage at CON3 pins 24~21. Expected 11.4~12.6V. 5. undefined: If supply voltage is not 11.4~12.6V, replace the Main PCB. 6. undefined: If supply voltage is correct, measure fan feedback voltage at CON3 pins 22~21. If voltage reads 0V or 5V (fixed), replace the motor. 7. undefined: Measure fan PWM voltage at CON3 pins 23~21. If voltage reads 0V or 5V (fixed), replace the Main PCB. 8. undefined: If all voltages are normal and fan runs freely, explain normal operation to customer.

How to Fix

1
Reset the unit and enter Test Mode 1 (press test button 1 time on Main PCB).
2
Open the freezer door and check air flow from the icing fan. If airflow is present (windy), go to step 4.
3
If no airflow, physically rotate the fan blade by hand. If blade feels sticky/seized, replace the icing fan motor.
4
Measure fan motor supply voltage at CON3 pins 24~21. Expected 11.4~12.6V.
5
If supply voltage is not 11.4~12.6V, replace the Main PCB.
6
If supply voltage is correct, measure fan feedback voltage at CON3 pins 22~21. If voltage reads 0V or 5V (fixed), replace the motor.
7
Measure fan PWM voltage at CON3 pins 23~21. If voltage reads 0V or 5V (fixed), replace the Main PCB.
8
If all voltages are normal and fan runs freely, explain normal operation to customer.
