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 Pin 20 to Pin 19. Expected: 11.4 to 12.6 V. If voltage is absent or out of range, replace Main PCB.
- 3
3. Open the freezer door and check for airflow from the evaporator fan. If airflow is strong (windy), proceed to step 4. If no airflow, proceed to step 5.

4. Measure fan motor feedback voltage at CON4 Pin 18 to Pin 19. If reading is 0 V or 5 V (fixed, not varying), fan motor feedback circuit is faulty.
- 5
5. Check for fan motor mechanical binding: rotate fan blade by hand. If fan feels sticky or obstructed, replace the fan motor.
- 6
6. Measure fan PWM voltage at CON4 Pin 47 to Pin 19. If reading is 0 V or 5 V (stuck), replace Main PCB.
- 7
7. If fan feedback voltage is not 0 or 5 V (is varying normally) but fan is not spinning, replace the fan motor.
- 8
8. If all voltages are normal and fan spins freely, explain to customer (intermittent condition).
