I have a blown 2.2 kw huanyang drive. One of the phases coming into the main board blew. Most of that board is fine and the control board has no problem. Plus all the plastic parts....anybody want it for parts? something to trade?
My dad has one of these as well that blew up on him when I was helping him install it. They would not return it of course. He will probably be bringing it to me the next time he comes to visit (he lives in SD and I'm in CO)
I wouldn't mind having a go at repairing one. Where are you located?
