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

1. undefined: Reset the unit, then enter Test Mode 1 (press Main PCB test button once). Open the freezer door and check for air flow from the duct. If air is flowing, proceed to step 4. 2. undefined: If no air flow, manually rotate the fan blade by hand. If the fan feels sticky or does not spin freely, replace the fan motor. 3. undefined: Check fan motor supply voltage at CON4 Pin 20 ~ Pin 19 in Test Mode 1. Should be 11.4–12.6 V. If voltage is absent, replace Main PCB. 4. undefined: With supply voltage confirmed, check fan feedback voltage at CON4 Pin 18 ~ Pin 19. If reading is 0 V or 5 V (not a valid feedback signal), replace the fan motor. 5. undefined: Check PWM signal voltage at CON4 Pin 17 ~ Pin 19. If reading is 0 V or 5 V (not a valid PWM signal), replace Main PCB. 6. undefined: If all voltages are correct and fan rotates freely, explain to customer (possible temporary obstruction).

Reset the unit, then enter Test Mode 1 (press Main PCB test button once). Open the freezer door and check for air flow from the duct. If air is flowing, proceed to step 4.
2
If no air flow, manually rotate the fan blade by hand. If the fan feels sticky or does not spin freely, replace the fan motor.
3
Check fan motor supply voltage at CON4 Pin 20 ~ Pin 19 in Test Mode 1. Should be 11.4–12.6 V. If voltage is absent, replace Main PCB.
4
With supply voltage confirmed, check fan feedback voltage at CON4 Pin 18 ~ Pin 19. If reading is 0 V or 5 V (not a valid feedback signal), replace the fan motor.
5
Check PWM signal voltage at CON4 Pin 17 ~ Pin 19. If reading is 0 V or 5 V (not a valid PWM signal), replace Main PCB.
6
If all voltages are correct and fan rotates freely, explain to customer (possible temporary obstruction).
