Service Manual - VMH 9/12/18/24 SU & VMH30/36S D Series
Remark:
Use a multimeter to test the DC voltage
between 2 port and 3 port of outdoor unit.
The red pin of multimeter connects with 2
port while the black pin is for 3 port.
When AC is running normal, the voltage
will move alternately between -25V to
25V.
If the outdoor unit has m alfunction, the
voltage will move alternately with positive
value.
If the indoor unit has a malfunction, the
voltage will be an unchanging value.
Remark:
Use a multimeter to test the resistance
of the reactor which does not connect
with capacitor.
The normal value should be around
zero ohm. Otherwise, the reactor has
malfunctioned.
