Outdoor Unit:
Malfunction of High Pressure Sensor
Remote
Controller
Display
JA
Applicable
Models
RXYQ5P~54P
Method of
Malfunction
Detection
Malfunction is detected from the pressure detected by the high pressure sensor.
Malfunction
Decision
Conditions
When the high pressure sensor is short circuit or open circuit.
Supposed
Causes
Defect of high pressure sensor system
Connection of low pressure sensor with wrong connection.
Defect of outdoor unit PC board.
Troubleshooting
∗
1: Voltage measurement point
∗
2: Refer to “Pressure Sensor, Pressure / Voltage Characteristics” table on P367.
(V2806)
Caution
Be sure to turn off power switch before connect or disconnect connector,
or parts damage may be occurred.
The
relationship
between the
∗
1
VH and high pressure
is normal (see
∗
2) when
voltage is measured between
X32A pins (1) and (3) of
outdoor unit PC
board (A1P)
(see
∗
1).
Replace the high pressure sensor.
Connect the high pressure sensor
and turn on again.
NO
NO
Replace outdoor unit PC board
(A1P).
YES
YES
The high
pressure sensor is
connected to X32A of
outdoor unit PC
board (A1P).
