The “Inverter Phase Check Module” from EDC International is meant to be a low-cost answer to facility staff’s problems when an inverter-controlled air conditioner fails. The difficulty is always to know whether it is the compressor or the inverter which is giving trouble, and the Inverter Phase Check Module can identify which is faulty.
The supply connections are disconnected from the compressor, and are connected to this module. When the inverter is switched on the six lights on the module should light up red, yellow, and blue. If the inverter PCB is faulty, one or more of these lights will not switch on, and this indicates the position of the fault. If all six lights are on, the PCB is fine, and the fault is with the compressor. If they are not all on, or one light is significantly dimmer than the rest, then the fault is with one or more of the output transistors on the PCB, or with the drive circuitry.
