How to Fix
- 1
Open freezer door and check air flow; if airflow is present and fan is running, proceed to voltage checks.
- 2
Reset unit and enter Test Mode 1 (push test button 1 time).
- 3
Check fan motor sticky: rotate fan blade by hand; if it feels sticky, replace the fan motor.
- 4
Measure fan motor power voltage at CON5 pins 13~16: normal = 10.8~13.2 VDC. If absent, replace Main PCB.
- 5
Measure fan PWM voltage at CON5 pins 13~14: normal = 2~4.5 VDC. If absent, replace Main PCB.
- 6
Measure fan feedback voltage at CON5 pins 13~15: should toggle between 0V and 5V. If signal is not toggling (stuck at neither 0V nor 5V), replace the fan motor.
- 7
If all voltages are correct and motor is not sticky, explain to customer.
