[ R-sensor ]
1) It senses the temperature of refrigerator compartment and controls R-fan ON / OFF.
2) How it works ;
Working Point Low ON Mid OFF High OFF
Working Temp. 2.65 C 0.3 C -1.7 C
Resistance
26.88 29.34 32.00
Sensing Voltage 2.90V 2.81V 2.74V
* In case refrigeration of refrigerator compartment is poor or insufficient though comp. and R-fan operate in
normal way ;
1) Cut J18 on M-PCB, then temp. is lowered -2 C than [Mid OFF point].
2) In addition to 1) action, cut J22 on M-PCB, then the temp. is lowered –1 C more.
