[1] Refrigerator compartment/

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.)

Normal

Is the motor damper (for refrigerator compartment/ slide compartment) covered with frost?

No

Check the refrigerator compartment thermistor

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".

Check the chilled compartment thermistor

	Replace the motor damper (for refrig-
