Error Code E FF

Freezer Fan Error / BLDC Fan Motor Abnormality for Freezer

What This Means

Freezer fan motor seized (ice or rust); BLDC feedback signal absent for more than 65 seconds; Loose connection at CON5; Defective fan motor drive IC or transistor; Fan motor winding failure

How to Fix

1. 1

   Reset the unit and enter Test 1 Mode by pressing test button 1 time

2. 2

   Open the freezer door and check for airflow

3. 3

   Note: while error code is displayed the fan is not working

4. 4

   If no airflow: manually rotate fan blade by hand — if sticky, replace motor (cause is ice or rust inside motor)

5. 5

   If fan rotates freely: check for loose connection at CON5

6. 6

   Check fan motor voltage at CON5: 5th pin to 9th pin should be above 10V; if below 10V, replace PCB

7. 7

   Check CON5 9th pin to 10th pin: expect 0 or 5V; if not, replace PCB

8. 8

   Check CON5 5th pin to 8th pin: expect 0 or 5V PWM signal; if not, replace fan motor

9. 9

   Fan error logic: fan stops 10s, retries 15s, repeats 3 times; if still failed, error code displays for 30 minutes and cycle repeats
