Regulation of R-sensor OFF Point
INPUT
J18, 22 on Main PCB
a. Regulation of R-sensor OFF point (1.5degree DOWN)
b. In case refrigeration of refrigerator is weak or insufficient, take the following action.
R-SENSOR
R26
R70
R71
a. R26 : R-SENSOR standard resistance in normal mode (31.4K )
b. R70 : In case of weak ref., cut J18 to down the standard resistance by 1.5deg(2K)
c. R71 : In case of weak ref., cut J22 to down the standard resistance by 1.5deg(2K)
R26 = Mid OFF point
R26 + R70 = Mid OFF point - 1.5 deg
R26 + R70 + R71 = Mid OFF point - 3.0 deg
