How to Fix

1
Reset unit and input Test Mode 1 by pressing test button once (display shows -00 00)
2
Open freezer door and check for airflow at fan outlet; note: fan does not run while error is displayed
3
If no airflow: check fan motor — rotate fan blade by hand; if sticky/stiff, replace motor (ice or rust in bearing)
4
If airflow present: check for loose connection at CON7
5
Measure fan motor voltage at CON7: pins 12-14: below 10V = change PCB; pins 14-16: 0 or 5V = change PCB; pins 12-14 signal: 0 or 5V = change motor
6
Fan motor wiring: PR pin 10, BO/BL pin 12, BO pin 14, GY/RD pin 16 at CON7
