Thermistor Resistance Check
Check No.01
Disconnect the connectors of the thermistors from the PCB, and measure the resistance of
each thermistor using a multimeter.
The data is for reference purpose only.
When the room temperature thermistor is soldered on a PCB, remove the PCB from the
control PCB to measure the resistance.
When the connector of indoor heat exchanger thermistor is soldered on a PCB, remove the
thermistor and measure the resistance.
