compartment door with
a magnet on the door
switch to check that
cold air blows from the
outlet.
Are the temperature of
refrigerator compart-
ment/ set to “High”?
Check the refrigerator compartment thermistor
Replace the motor damper (for refrig-
erator compartment/ slide chilled
compartment)
❈Motor damper is combined with
control panel assembly.

Expose the damper (for refrigerator compartment/ slide com-
partment) so that its operation can be visibly checked and
conduct an ice-making test. Does the baffle open/close ?
(Wait 1 minute for self-check).
(See “Self check method and its operation,1 Ice making
test operation” at page 14.)
Put refrigerator compartment thermistor into ice water (0:), dis-
connect the 4-pin connector, and measure resistance between
3 (white) and 4 (white).
•Resistance at 0: :approx. 6-7k".
Put chilled compartment thermistor into ice water (0:), dis-
connect the 6-pin connector, and measure resistance between
