Diagnosis

Countermeasure

YES

Replace the low pressure sensor.

Are the

connection of low pressure

sensor connectors (at sensor side

and PCB side) OK?

Are the

pressure (actual

measurement) matched with the value

indicated on the remote

controller?

normal condition

restored?

YES

Correct low pressure sensor

connector connection.

Is refrigerant amount

charged properly?

Is there any anomaly on the

refrigeration circuit?

Defective outdoor control

PCB

Replace.

(Defective low pressure

sensor input circuit)
OK

2. Error detection method

When anomalous voltage

(pressure) is detected

3. Condition of Error displayed

If the pressure sensor detects 0V

or lower and 3.49V or higher for

5 seconds continuously within

2 minutes to 2 minutes 20

seconds after compressor ON,

the compressor stops. When

the compressor is restarted

automatically after 3-minuts

delay, if this anomaly occurs 3

times within 40 minutes

4. Presumable cause

• Defective low pressure sensor

connection

• Defective low pressure sensor

• Defective outdoor control

PCB

• Improper amount of

refrigerant

• Anomalous refrigeration

circuit
