It could be that the board has failed....or the caps, or it could be that the compressor is shot. Have you put a clamp on ammeter on the leads that go to the compressor? Any draw at all?

There is a post on here about my experience with a melt down of one of the control boards. you will want to look closely at the connectors that go from the board to the compressor.

Also, the caps are located right behind the board if I remember correctly.
