2.FUNCTIONS
Control Resistance of R sensor OFF Point
- When the refrigeration of refrigerator is poor or weak though Fan and COMP are working continuously,
the following actions are recommended for service.
(1) Resistance (R25) : Default resistance (31.4Kohms)
(2) Resistance (R26) : Cut the “J1” off to reduce basic resistance by 1.5°C. (2Kohms up)
(3) Resistance (R27) : Cut the “J2” off additionally to reduce basic resistance by 1.5°C. (total 4Kohms up)
※ R25 = R-SENSOR OFF point
R25 + R26 = R-SENSOR OFF point - 1.5°C
R25 + R26 + R27 = R-SENSOR OFF point - 3°C
