Control Resistance of R sensor OFF Point
A. LOW COOLING OPTION
- When the refrigeration of refrigerator is poor or weak though Fan and COMP are working continuously,
the following actions are recommended for service.
●
Resistance (R39) : Default resistance (31.4Kohms)
●
Resistance (R36) : Cut the “J1” off to reduce basic resistance by 1.5
°
C. (2K
Ω

●
Resistance (R31) : Cut the “J2” off additionally to reduce basic resistance by 1.5
°
C. (total 4K

R39 = R-SENSOR OFF point
R36 + R39 = R-SENSOR OFF point - 1.5
