What This Means

No feedback signal from freezer fan motor for more than 65 seconds; Fan motor mechanically stuck (sticky bearings); Defective BLDC motor drive IC or transistor; Defective Main PCB fan motor output

How to Fix

1. 1

   Step 1: Reset unit and enter Test Mode 1 (press test button 1 time).

2. 2

   Step 2: Measure fan motor supply voltage at CON4 pins 20-19 — expected 11.4 to 12.6V; if absent, replace Main PCB.

3. 3

   Step 3: Open freezer door and check airflow — if windy, proceed to Step 4; if no airflow, rotate fan by hand.

4. 4

   Step 4: Rotate fan motor blade by hand — if sticky or binding, replace fan motor.

5. 5

   Step 5: Measure fan feedback voltage at CON4 pins 18-19 — expected NOT 0 or 5V; if 0V or 5V, replace fan motor.

6. 6

   Step 6: Measure fan PWM voltage at CON4 pins 17-19 — expected NOT 0 or 5V; if 0V or 5V, replace Main PCB.

7. 7

   Step 7: If all checks are normal, explain to customer.
