1. Connector connection defective, open
2. Thermistor failure3. Main PCB failure
OK
Check Point 1 : Check the connector connection and cable open
Connector connection state check
Check Point 2 : Check the thermistor
Thermistor characteristics check (Disconnect the thermistor from the PCB and check.)
* For the thermistor characteristics, refer to the "Service Parts Information 5".
Check Point 3 : Check voltage of Main PCB (DC5.0V)
Main PCB (CN65:1-2) voltage value = 5V
Remove the thermistor from Main PCB, check the voltage.
