got an old 407c vrf Mitsubishi heavy industries system that is taking comp out for fun. latest fault is e5. found system with no gas . Found leak and repaired and re charged. but still unable to get comp to run. checked windings to earth and no resistance . Unable to give the model of comp but does any one know what resistance value i should have on a 3 phase inverter driven comp ? Could a faulty inverter take out comp, or would the loss of oil from the leak take the comp out before faulting on a low pressure fault?

Have you checked running amps ? Could be seized

resistance should be equal between any 2 windings usualy around 1-3 ohms
