15.4.10 H30 (Compressor Discharge Temperature Sensor Abnormality)

Malfunction Decision Conditions

•

During startup and operation of cooling and heating, the temperatures detected by the outdoor discharge pipe

temperature sensor are used to determine sensor errors.

Malfunction Caused

•

Faulty

connector

connection.

•

Faulty

sensor.

•

Faulty

PCB.

Troubleshooting

When abnormality indication starts again

Check the outdoor discharge pipe temperature sensor:

●

Plug out connector from the outdoor unit PCB

●

Measure the resistance of the outdoor discharge pipe
temperature sensor

For safety reason and to prevent
component breakdown, always switch
off the power before remove and
connect the component.

Is the measured resistance of the outdoor discharge pipe
temperature sensor matches the value specified in its
characteristic chart?

●

Defect in outdoor discharge pipe

●

Replace the outdoor discharge pipe
temperature sensor

●

Defect in outdoor unit PCB

●

Replace the outdoor unit PCB

Check the connector connection:

●

Turn off the power

●

Check the connector connection

Is the connector connection normal?

YES

●

Connector poor contact

●

Correct the connection

YES
