REMARKS:
• Use a multimeter to test the DC voltage between the 2 port (or S or L2 Terminal) and the 3 port (or N or S Terminal) of the outdoor unit.
• The red pin of the multimeter connects with the 2 port (or S or L2 port) while the black pin is for the 3 port (or N or S Terminal).
• When the unit is normal running, the voltage is moving alternately as positive values and negative values.
• If the outdoor unit malfunctions, the voltage remains a positive value.
• If the indoor unit malfunctions, the voltage does not change.
• Use a multimeter to test the reactor resistance which does not connect with the capacitor.
• The normal value should be around zero ohm. Otherwise, the reactor has malfunctioned.
