Also displayed as: FF E
How to Fix
- 1
Reset the unit and enter Test Mode 1 (press test button 1 time).
- 2
Open the freezer door and check for airflow. If airflow is present (windy), go to step 4.
- 3
Rotate the fan blade by hand. If it feels sticky or stiff, replace the fan motor.
- 4
Check fan motor supply voltage at CON7 pin 12 to pin 14: should be 12V. If absent, replace Main PCB.
- 5
Check fan control signal voltage at CON7 pin 16 to pin 14: should be 0V to 5V (PWM). If absent, replace Main PCB.
- 6
Check fan feedback voltage at CON7 pin 10 to pin 14: should be 0V to 5V. If absent or constant, replace the fan motor.
- 7
If all voltages are correct and fan still fails, explain to customer.
