211
Service Diagnosis
4.38 High Pressure Sensor Abnormality
Error Code
JA
Applicable
Models
All outdoor units
Method of Error
Detection
Error is detected from the pressure detected by the high pressure sensor.
Error Decision
Conditions
The high pressure sensor is short circuit or open circuit.
Pressure range: 0-4.3 MPa (0-624 psi)
Supposed
Causes
Defective high pressure sensor
Connection of low pressure sensor with wrong connection
Defective outdoor main PCB
Disconnection of high pressure sensor
Troubleshooting
Caution
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
Replace the outdoor main PCB
(A1P).
Replace the high pressure sensor
(S1NPH).
YES
NO
Replace the outdoor main PCB
(A1P).
NO
Replace the high pressure sensor
(S1NPH).
YES
YES
NO
YES
Reset the operation, and then
restart the outdoor unit.
Are the
characteristics of the
high pressure sensor
normal?
Connect to the high-pressure
sensor and then reconnect to the
power.
NO
Does
the high-
pressure sensor
connect to the corresponding
connector of the outdoor
main PCB (A1P)?
Are the characteristics of the
high pressure sensor normal? (Make a
comparison between the voltage
characteristics and the
gauge pressure.)
Is the PCB pressure detection
normal? (Make a comparison between
the checker pressure data and
the voltage
characteristics.)
