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.
