[F-sensor (A)]
1) It senses the temperature of freezer compartment and control Comp., F-fan ON/OFF
2) How it works;

Working Point
* In case temperature of refrigerator compartment is weak or insufficient,
though comp. and R-fan operate in normal way;
1) Cut J18 on the M-PCB, then temp. is lowered 1.5℃ than [Mid OFF point]
2) Cut J18 and J19 on the M-PCB, then the temp, is lowered 3 ℃
