Troubleshooting
∗
Refer to “Thermistor Resistance / Temperature Characteristics” table on P362.
NO
NO
Replace discharge pipe thermister.
Replace main PCB ( A1P).
Connect the service checker.
Press reset and start operation
again.
Check if
discharge pipe
thermister property is
normal.
(∗1)
Check if
temperature of
discharge pipe by using
service checker is the same with
actual measurement value
of discharge pipe
thermister.
YES
· Discharge pipe thermister is normal and the
temperature detection of the main PCB is also normal.
· Actually the temperature of discharge pipe is high.
Check 3 Remove the factor of overheat operation
referring to P. 305.
Service Checker
Connect the service checker to compare the
temperature of discharge pipe by using service
checker with actual measurement value of discharge
pipe thermister (Refer to ∗1).
∗1: Compare the resistance value of discharge pipe thermister and the value based on the surface
thermometer.
(Refer to P. 362 for the temperature of thermister and the resistance property)
Caution
Be sure to turn off power switch before connect or disconnect connector,
or parts damage may be occurred.
