Is anomalous 

pressure detected?

Is the 

connector of the 

faulty sensor inserted 

properly to the connector on 

the outdoor control 

PCB?

Check and save the data of 

operating condition.

Check the conditions 

whether it occurs 

immediately after the 

power on or during 

operation or stopping.

Check also sensor value.

Insert connector securely 

and restart operation.

Temporary malfunction by 

noise. Correct if source of 

noise is identified.

Replace sensor.

Replace outdoor control 

PCB.

2. Error detection method

Detection of anomalous voltage 

(pressure)

Operating range

High pressure 0 – 4.15MPa

Low pressure 0 – 1.7MPa

3. Condition of error displayed 

Sensor output voltage

0V or lower

3.49V or higher

Detected for 5 seconds within 

2 minutes to 2 minutes and 20 

seconds after the compressor 

ON.

4. Presumable cause

• Disconnected sensor harness

• Disconnected sensor 

connector

• Faulty sensor

• Defective outdoor control 

PCB

• Faulty installation conditions

• Insufficient airflow volume

• Excessive or insufficient 

refrigerant amount

Note:

*1 E54-1/1 time flash: Low pressure sensor anomaly, E54-2/2 times flash: High pressure sensor anomaly
