Reset unit and input Test Mode 1 by pressing test button once
2
Check condenser fan rotation; note: fan does not run while error is displayed
3
If no rotation: check fan motor and surroundings — rotate by hand; if sticky, change motor
4
If rotating: check for loose connection at CON7
5
Measure condenser fan motor voltage at CON7: pins 4-6: below 10V = change PCB; pins 6-8: 0 or 5V = change PCB; pins 6-2: 0 or 5V = change motor
6
C-FAN motor wiring: GY pin 7, PK pin 4, WH/RD pin 6, BK pin 3 at CON7
