    Our air keeps cycling off before the unit is cooled down, any ideas?

    Adjust the t-stat to a lower setting. Some of these may not read correctly. Not calibrated. Good luck.

      You do not say where you are located or if this happens only until cooled down to the desired setting. However, when in extremely high humidity, we run the A/C fans on high until the interior begins to cool down some and the inside humidity drops a little. Otherwise they may freeze up and shut down prematurely to thaw out. Dirty filters can cause the same issue, so make sure filters are clean.

          Turned air off, pushed zone and mode at the same time. Int came up on the screen, reset to zones 1 and 2, works now.

            Thanks for the info! Always nice to learn about an issue, especially when it's an easy fix.

              With regards to your A/C issue, what name and model of thermostat are you working with? I think those have changed over the years, and I don't know if the fix for yours would necessarily work on other models.

                Mine cycles all the time. Replaced sensor in ceiling, replaced thermostat and did the reset mentioned above, replaced circuit board, cleaned filters, etc. Still cycles on and off. If I set it on 40° it will freeze you out. I'm close to replacing the whole unit but my gut tells me that wouldn't work either. Don't know what to do? Maybe buy a older designed one where it vents at the unit and the controls are at the unit?

                  Like Terry said, this may depend on year, make and model of your A/C's and the thermostat. I know when we had a new A/C installed that was 6 years newer than the other one, Indiana Interstate RV, who was doing the service, had quite a time getting the two A/C's to work together. After trying two different A/C control boards recommended by Dometic, Paul Cross ended up modifying one of the boards to get them both to work.
