A/C Pros in Highlands Ranch area?

[Ramsker]

Well . . . I verified power from the panel to the switch with the fuse. And I have power to the door switch and power from the door switch to the board. I'll try the transformer check a little later--although not sure I know what to do for that exactly. Will try to follow your instructions with the wire identification.

Edit: Anything beyond what I checked to this point is probably well beyond my abilities to fix anyway, unfortunately.
