Mitsubishi Electronics Measure the resistance with a tester.

Fan grill of the
freezer compartment.
Measure the resistance with a tester.
(Ambient temperature:Room temperature 15oC ~ 25oC)
In the drip tray under
the evaporator of the
freezer compartment
Measure the resistance with a tester.
(Ambient temperature:Room temperature 15oC ~ 25oC)
Resistance measured under Defrost thermistors
the ambient temperature from Thermistor resistance radiator
-50: to +50: (kΩ)against temperature of the freezer
compartment.
1. 200" to 500k" F-thermistor, control
............normal panel of the refrigerator
2. Out of the above range compartment.
............abnormal
Thermistor Check Procedure
Thermistor resistance will vary
with the change of temperature. (oC)
Take the temperature around the thermistor, Temperature
and then measure resistance using a tester.
The relation of resistance and temperature is as shown on the above graph.
