[QUOTE=brack31;1242483]Do you have the Mode set to Cool or is it on Fan? It needs to be set on Cool for the A/C to turn on. With the fan set to high, once the temperature set point is reached, the A/C compressor turns off but the fan stays on to keep air moving. (If that makes sense, and in case you didn't already know)

Hey Glen, its set to cool - I have cold air coming into the coach. its just not enough.

I'll take picture tomorrow - maybe that will help...

Thanks For the help!

I have another thread about this, so obviously have the same issue with my 2017 RBOK. it will keep it around 15 below outside temp but ac' runs nonstop. I also have the upgraded insulation and thermal Windows which I'm calling bs on at this point. I added 2" pic to the return ducts to hold them open but don't think it helped. The exhaust temp is as low as 55 in the heat of the day so it's blowing cold. Just not enough air and too much heat coming in. It doesn't help that I have 2 huge shower skylights plus 4 exhaust fans and the door Windows. All of the skylights are now covered with insulation and still doesn't keep up as I would expect. The only the I haven't done is pulled the roof units to check the wiring holes..
I have really struggled to find the right thermostat settings. Lately have been setting the back ac to 65 so it runs all day otherwise it would shut off while the rest of unit was hot. I also taped up the vents in the bedroom and master bath to force more air to the rest of unit. Again, all of this didn't solve the problem but I'm guessing it helped a bit.

Looking at the return and exhaust divider, you can see where it has come loose from the two sided white tape.
Therefore allowing intake and return air to mix.

I just talked to my BIL this weekend and his A/C had the same problem shown in Turbs' pic. Apparently it's a lot more common a problem than I thought.
