Hi, i recently bought a haier hfd647ss french door fridge, it runs an embraco vegy 7h compressor, controlled by a VCC3 2456 inverter control unit. on testing the compressor gives me 6.6 ohms across all pins as per specs, 780 meg to earth (by megger), however i get 0 ohms between pins by megger (set to 250v (running voltage)) when powered the compressor doesnt run and the inverter is putting out 120v to each pin. the inverter specifies a running voltage of 230v 53hz-110hz. the inverter is getting 240vac from the pcb and a 10vac control signal. ive tried to find the specs on this system to no avail. so is the control voltage incorrect, is the voltage output from inverter incorrect or is 0 ohms by megger inbetween the windings of the vcc compressor incorrect. thanks guys.
