Resistance of R-sensor Mid ON/OFF Point

CONTENTS REMARKS

Compensation of R-sensor ON/OFF temp. (down)

In case temperature of refrigerator compartment is weak or insufficient, take the following action.

FRS(N)-U20IA FRS(N)-U20DA

J2

R36 : R-SENSOR standard resistance in normal mode (31.4K)

R37 : In case of weak ref., cut J1 (or J18) to down the standard resistance by 1.5deg(2K)

R38 : In case of weak ref., cut J2 (or J19) to down the standard resistance by 1.5deg(2K)
