CONTENTS REMARKS
Regulation of R-sensor OFF point (1.5degree DOWN)
In case refrigeration of refrigerator is weak or insufficient, take the following action.
R- SENSOR
R26
R70
R71
R26 : R-SENSOR standard resistance in normal mode (31.4K ).
R70: In case of w eak ref., cut J18 to down the standard resistance by 1.5deg(2K).
R71 : In case of weak ref., cut J22 to down the standard resistance by 1.5deg(2K).
R26 = Mid ON/OFF point
R26 + R70 = Mid OFF point - 1.5 deg
R26 + R70 + R71 = Mid OFF point - 3.0 deg
