R-Sensor
- It senses Refrigerator(Fresh Food Compartment) temperature and controls ON/OFF of R-Fan.
- How it works ;
4
Light Sensor
- It senses the amount of ambient light and controls the RPM of F/R/C-Fan.
- How it works ;
• When the customers claim that cooling power or refrigeration of Refrigerator(Fresh Food Compartment) is poor
though COMP and R-Fan work in normal way ;
1) Move the Slide Switch on M-PCB to "Weak REF" to reduce the Middle OFF Point by -1.5 °C
2) In addition to 1), cut Jumper J1 to reduce Middle OFF Point by -3.0 °C
