That relay will short out the inrush limiting resistor once the big DC bus caps have been charged and the internal PSU comes up. As m_c says, it's more likely to be a symptom rather than the cause. If you manage to replace the green resistor, I'm pretty certain you will simply roast it again.

I think the question is whether you replace the HY inverter with a similar one or spend a bit more for an industrial drive - Jazz is recommending a new HY one.
