It seems they tend to be stuck on the heat function when I attempt to start them, however, I will pay closer attention in the future. Other than our trip last fall, the only use they have seen since I purchased the rig has been a few cycle runs to keep the seals in shape. The units were used for only about a year prior to me buying this coach, not under warranty I suspect, but I do have the paperwork and dealer info. Again, thank you all for the extremely useful information. Once I knew what to go after, I used the control box to switch from off to cool without allowing the unit to start. After a few tries, I heard a definite difference in the sound from the unit above me, at that point I allowed it to continue to start the compressor and bingo, she had switched to cooling. Since that time, both units have cycled off and on frequently without issue.....so far.
