my old unit is a coleman model#7633A8964 ducted do I have to buy a new ceiling assssemby and a new therostat or will my old one work

We just installed our new unit, just plugged into old ceiling assembly and used our old thermostat. Turn on to check that it works, but don't leave it on. We found out that it needs to settle before leaving it on for a long time.

I have no idea what my old unit is on my 04 Springdale. The opening is 14” and it is ducted. Will this work with my existing set up?

If it is a Coleman AC only unit then yes. If another brand (Dometic, Carrier, Advent) you will need other items as well.

Do you have to order the control board separately

If you have an existing Mach 3 system then you just use your old grill and control box. Providing they are functional.
