I removed the shroud last fall to have a look see,it took awhile to remove the 4 screws that held it down(rusted) but I got them out and the shroud came off ok,it does not have a opening in the top. When I ran the AC the fan went on all three speeds but I could not hear or feel the compressor. When I get Back to see the a/s (if it ever warms up here)I'll check that transformer (if I can find it)....I did not see much of anything to work on when I was up there but Ididn't know what I was looking for. I just saw the fan,compressor and the coils.
Thanks Frank
