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
