Error Code E FF

Freezer fan (BLDC) motor error

How to Fix

1. 1

   Reset the unit and enter TEST MODE 1 (push test button 1 time).

2. 2

   Measure fan motor supply voltage at CON4 pins 20 to 19. Expected: 11.4–12.6V.

3. 3

   If supply voltage is not 11.4–12.6V: replace Main PCB.

4. 4

   If supply voltage is correct: open freezer door and check air flow. If air is not blowing (not windy): proceed to check motor.

5. 5

   If air flow is present but weak: check fan feed-back voltage at CON4 pins 18 to 19 in TEST MODE 1. Expected: not 0V or 5V (should be variable).

6. 6

   If feedback voltage is 0V or 5V: change freezer fan motor.

7. 7

   If feedback voltage is correct but motor is suspect: check fan PWM voltage at CON4 pins 17 to 19. Expected: not 0V or 5V.

8. 8

   If PWM voltage is 0V or 5V: replace Main PCB.

9. 9

   Physically rotate fan blade by hand. If fan feels sticky or stiff: replace fan motor.

10. 10

    If all voltages are correct and fan rotates freely: explain situation to customer.
