pipe thermistor
property is normal.
(

YES
Replace the discharge pipe
thermistor.
Connect the service checker to compare the
temperature of discharge pipe by using service
checker with actual measurement value of discharge
pipe thermistor (Refer to
∗
1).
Service Checker
Check if temperature of
discharge pipe by using
service checker is the same
with actual measurement
value of discharge pipe
thermistor.
∗
1: Compare the resistance value of discharge pipe thermistor and the value based on the surface
thermometer.
NO
NO
Replace the main PCB
(A1P).
· Discharge pipe thermistor is normal and the
temperature detection of the main PCB is also normal.
· Actually the temperature of discharge pipe is high.
Check 11 Remove the factor of overheat operation
