Troubleshooting
Note:
∗1. Compare the resistance values of the discharge pipe
thermistor with measurements of a surface
thermometer.
(For temperature and resistance characteristics of a
thermistor, refer to P.371.)
∗2. Compare the discharge pipe temperature checked
by the Service
Checker with the resistance of the thermistor (refer to
∗1).
Refer to P.351.
NO
YES
YES
Replace the
discharge pipe
thermistor.
Are
discharge
pipe thermistor
characteristics
normal?
(∗1)
NO
Replace the main
PCB.
Is PCB
detection temperature
normal?
(∗2)
· The discharge pipe thermistor is normal and the
main PCB temperature detection is also normal.
· In fact, discharge pipe temperature is rising.
