Remarks:
• Use a multimeter to test the DC voltage between 2 port (or S or L2 port) and 3 port (or N or S port) of
outdoor unit.
The Red pin of multimeter connects with 2 port (or S or L2 port), while the Black pin is for 3 port (or N
or S port).
• When AC is normally running, the voltage is moving alternately as positive and negative values.
• If the outdoor unit has malfunction, the voltage will move alternately with positive values.
• While if the indoor unit has malfunction, the voltage will be a certain value.

S and N, or L2 and S, or 2 and 3.
• Use a multimeter to test the resistance of the reactor which does not connect with capacitor.
• The normal value should be around 0
Ω
. Otherwise, the reactor must have malfunction.
Note: The picture and the value are only for reference, actual condition and specific value may vary.
• Use a multimeter to test the resistance of the reactor which does not connect with capacitor.
• The normal value should be around 0 . Otherwise, the reactor must have malfunction.
