Dometic Ceiling Assembly for Non-Ducted installations with Wall Thermostat

Which Dometic ceiling assembly part numbers fit non-ducted installations with a wall thermostat?

This collection covers the Dometic non-ducted ceiling assemblies designed to pair with a wall-mounted thermostat rather than a ceiling-mounted control. Common part numbers in this family include 3314851.000 and 3313470.000 series assemblies. Confirm your existing rooftop unit model and the thermostat type wired in your RV before ordering. If you are working with a different Dometic configuration, the FreshJet 5 heat pump ceiling assembly for non-ducted installations may be the correct match.

What is the difference between ducted and non-ducted ceiling assemblies?

A non-ducted ceiling assembly delivers cool air directly through the assembly grille into a single living space, which works for most short-coach and mid-size RVs. A ducted assembly routes air through ceiling ductwork to multiple vents throughout the coach. The two are not interchangeable. If your RV is plumbed for ductwork, look at the Coleman Power Saver HP ducted ceiling assembly instead.

Do I need a wall thermostat already installed to use these assemblies?

Yes. Every assembly in this collection is built for systems where the temperature control lives on the wall, not in the ceiling unit. The ceiling assembly has the grille and airflow components but no on-board control panel. If your rig uses a ceiling-mounted control, you will need a different assembly. Verify the existing thermostat wiring before purchase, or text our team at 817-984-1852 with your RV model and current part numbers.

Will this fit my Coleman or Furrion rooftop air conditioner?

No. These ceiling assemblies are engineered specifically for Dometic rooftop units. Coleman-Mach and Furrion systems use different mounting patterns and electrical connectors. For Furrion installs, see the Furrion Original non-ducted ceiling assembly. For Coleman soft start upgrades on existing units, the Coleman RV air conditioner soft start kit is a separate compatibility path.

How is this collection shipped, and what should I check on arrival?

Ceiling assemblies ship via ground freight in protective packaging. Inspect the grille, foam gasket, and assembly housing for shipping damage before installation; report any issues within 48 hours of delivery. Free shipping applies on qualifying orders over $100. Most installs take 45 to 90 minutes with basic hand tools and a second person to support the assembly during mounting.
