18.4.7 H23 (Indoor Pipe Temperature Sensor 1 Abnormality)

Malfunction Decision Conditions



During startup and operation of cooling and heating, the temperatures detected by the indoor heat exchanger

temperature sensor are used to determine sensor errors.

Malfunction Caused



Faulty connector connection.



Faulty sensor.



Faulty PCB.

Troubleshooting

Check the indoor air temperature sensor:

Is the measured resistance of the indoor intake air
temparature sensor matches the value specified in its
charactetistic chart?

•

Plug out connector from the indoor unit PCB

•

Measure the resistance of the indoor intake air

temperature

sensor

•

Defect in indoor intake air temperature sensor

•

Replace the indoor intake air temperature

sensor

•

Defect in indoor unit PCB

•

Replace the indoor unit PCB
