Troubleshooting by Indication on the Remote Controller
Caution Be sure to turn off the power switch before connecting or disconnecting the connector, or parts may be damaged.
Connect the service checker.
Press reset and start operation again.
thermistor property is
Connect the service checker to compare the temperature of discharge pipe by
using service checker with actual measurement value of discharge pipe
discharge pipe by using
service checker is the same with
actual measurement value
of discharge pipe
· Discharge pipe thermistor is normal and the temperature detection of the
main PCB is also normal.
· Actually the temperature of discharge pipe is high.
Remove the factor of overheat operation referring to P.216.
*1: Compare the resistance value of discharge pipe thermistor and the value based on the surface thermometer.
(Refer to "Thermistor Resistance / Temperature Characteristics" table on P.241.
Replace the discharge pipe
Replace the main PCB (A1P).
