Service Diagnosis
Note:
∗
1. Make a comparison between voltage measured by the pressure sensor and that read by the
pressure gauge.
(The pressure sensor makes measurement of voltage at its connector block to convert it to
pressure.
)
Refer to page 297.
Replace the outdoor unit
main PCB (A1P).
NO
YES
Check
if the high
pressure value and
the actual value
measured by
pressure sensor
are the
same.
-The high pressure sensor is normal, and pressure detection with the outdoor
unit main PCB is also normal.
-The high pressure has really become high.
CHECK 1
: Eliminate factors that cause the high pressure to rise.
Compare the high pressure value checked with the Service Checker and
the actual value measured by pressure sensor (
∗
1).
