Error Code E IF

Defect of BLDC fan motor for ice making (icing fan)

Also displayed as: E IF

How to Fix

1. 1

   Power cycle the unit and enter Test Mode 1 (press TEST button once on Main PCB).

2. 2

   Open the freezer door and check for airflow from the icing fan; if airflow present, go to step 5.

3. 3

   If no airflow, manually rotate the icing fan blade by hand. If sticky or seized, replace the icing fan motor.

4. 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. 5

   If motor supply voltage is absent, replace the Main PCB.

6. 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. 7

   If feedback voltage is fixed at 0V or 5V, replace the icing fan motor.

8. 8

   If feedback is correct, measure PWM voltage at CON4 9th Pin to 11th Pin; expected not fixed 0 or 5V.

9. 9

   If PWM is fixed 0V or 5V, replace the Main PCB.

10. 10

    If all voltages are correct, explain normal operation to customer.
