Remark:
Use a multimeter to test the DC voltage
between
terminal L 2 and terminal 3 ( S ) of
outdoor unit. The red pin of multimeter
connects with 2 port while the black pin is
for
terminal 3( S ) .
When AC is normal running, the voltage
will move alternately between -25V to
25V.
If the outdoor unit has malfunction, the
voltage will move alternately with positive
value.
I f the indoor unit has malfunction, the
voltage will be a steady 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
is
malfunction ing .
