5.1 Thermistor Resistance Check
Check No.01
Measure the resistance of each thermistor using multimeter.
The resistance values are defined by below table.
If the measured resistance value does not match the listed value, the thermistor must be replaced.
Disconnect the connector of thermistor ASSY from the PCB to measure the resistance between
the pins using multimeter.
To check the thermistor soldered on a PCB, disconnect the PCB from other PCB/parts, and
measure the resistance between the both ends of soldered thermistor.
