12-2 CHECK B

B1. LED Blinks once, then repeats. (FCT0 Fault: A-inverter)

12-2 CHECK B

B2. LED Blink two times, then repeats (Stroke Trip)

- Purpose: Detecting motor current and voltage error.
- Check voltage at

(motor voltage),

(motor current)

and

(capacitor voltage) when compressor is off.

Spec:

point A

point B

point C

Points A, B & C 2.5V ± 0.3V

- Purpose:

.

- Case 1
If compressor doesn’t work and LED blinks
Cause: Possibility harness from compressor to PCB might be defective.

-Case 2
If compressor works intermittently and LED blinks
Cause: Condenser fan or freezer fan is not running. Sealed system problem such as moisture restriction, restriction at capillary
tube or refrigerant leak.

Logic: Compressor is forced to off and then tries to restart after 1 minute.

Prevent abnormally long piston strokes
