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
control?
Is
normal condition
restored?
NO
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 4.0V 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
