How To Test Inverter Compressor. This video is intended to help guide qualified technicians troubleshoot inverter compressors. You cant check voltage out of the inverter.
Look for the results. Similarly the outdoor fan used is DC fan instead of the conventional AC fan. From what i have learned so far the unit electronics are converting the input 240v AC to DC and outputing a variable voltage 3 phase to the compressor.
It is best to test inverters with no compressors connected especially if you expect the compressor is at fault.
Disconnect the compressor from the inverter board then check all 3 windings for continuity. You can ohm the compressor. Hi Is it possible to test compressors used in DC inverter units using a standard Inverter. The problem i have is with some Hitachi units which just stop as soon as the compressor starts to ramp up.
