Disconnect the thermistor connector plug from the
control panel circuit board.
NOTE: The control panel assembly has been
removed for clarity only. There is no
need to remove the control panel
assembly to conduct this test.
Using an ohm meter (Ω), measure the resistance
value of the thermistor.
To do this, measure the resistance between the
two metal contacts in the plastic connector plug
as shown.
NOTE: The resistance of the thermistor will
increase as the fridge gets colder.
Measure the temperature of the plastic liner at the
base of the fridge.
For all fridges
Thermistor resistance values
Temperature of plastic
liner at base of fridge
Resistance Value
10°C (50°F)
18k Ω
5°C (41°F)
22k Ω
0°C (32°F)
28k Ω
-5°C (23°F)
35k Ω
-10°C (14°F)
44k Ω
NOTE: At approximately 20°C (68°F) degrees,
the thermistor should read between 8-14k Ω.
Check the measured resistance against the
resistance values in the table for the given
temperature.
NOTE: Allow a variation of ± 5k Ω between the
measured resistance and the values in
the table.
TEST PASS
If the measured resistance is within ± 5k Ω of the tabulated value, the thermistor is functioning
correctly.
TEST FAIL
If the measured resistance varies greatly from the tabulated value or an open circuit is detected, the
thermistor is faulty and should to be replaced (refer to section 9.22).
