Measure the resistance with a tester.(Ambient temperature:Room temperature 15oC ~ 25oC)
Measure the resistance with a tester.
(Ambient temperature:Room temperature 15oC ~ 25oC)
Measure the resistance with a tester according to the following graph.
(Thermistor resistance values against temperature)
Resistance measured under the ambient temperature from -50oC to +50 oC
1. 200 Ωto 500kΩ............normal
2. Out of the above range ............abnormal
(kΩ) Thermistor Check Procedure
Thermistor resistance will vary
with the change of temperature.
Take the temperature around the
thermistor, and then measure
thermistor resistance using a
tester.
The relation between resistance
and temperature is as shown on
the left side.
Trouble shooting with self-check
(1) If the self - check indicates the abnormality of thermistor right after the power is
turned on, measure the resistance of the thermistor.
If the circuit of thermistor is short , check the element of the thermistor and the
contact of the connector.
(2) When the self - check indicates the abnormality of thermistor a few seconds
after the power is turned on , check the contact of the connector.

6.3 FLOW CHART OF SELF-CHECK
(1) Trouble shootin with self-check
This refrigerator has self-check feature to clarify and indicate where & what the trouble is. It can be checked that
there is something wrong with electronic circuit and electric parts.
Remark
(2) Timin of self-check
 Defrost heater and related parts : Self-check is conducted after defrosting.(Make sure to confirm the display before unplugging
because it is automatically reset once the power cord is pulled out.)
 Ice maker and related parts : To check the ice- making and then, check the blink amount of LED see the reference as (3)
 Fan motor and related parts : To check the blink amount of LED see the reference as (3)
 Thermistor and related parts : Self-check is continuously working.
Caution: The self-check will automatic start to begin power supply. But in the portion of the abnormality show the detail as (3) .
And the caution checking couldn't be summarized, please use self-check means by using operation panel.

During the ice making test
mode,watch the operation of ice
maker gear box and water pump in
refrigerator.
Is trouble no longer
displayed?
No
1.) Self-check cannot detect abnormalities of the
following parts. See page 11~13 for trouble
criterion of main parts.
- Freezer & refrigerator door sw NG
- Thermo heater NG ( Water pipe / Vegetable
case heater etc.)
- Motor damper NG
- Water pump motor NG
2.) If the abnormality is found when power is
turned on, compressor and fan motor will be
suspended for 20 minutes.

(3) LED trouble display and the check point
(3.1) LED trouble display : follow the procedure of "self check method
and its operation" at page 11. Trouble is indicated by the blinking number
of ice making stop LED.
∗
When several troubles occur, smaller blinking number of LEDs has to be indicated first.
