If you have power at the compressor, everything is working correctly. The white wire just runs off to ground somewhere.

Ok, I see where yer at. Yeah, if the system operates properly if you bypass the switch, replace it. There are two though, one on the high side, and one on the low side. Make sure you get the right one.
