Replace or upgrade the interior ceiling assembly on your Dometic low-profile rooftop air conditioner. Part 3314850.000 is a factory-style non-ducted ceiling assembly that mounts directly through a standard 14-inch by 14-inch roof opening and works with a wide range of Blizzard NXT, Brisk II, and Penguin II units. Adjustable vents let you direct conditioned air where you need it, and a built-in return air filter keeps debris out of the evaporator coil. Thermostat is sold separately.
The ceiling assembly is the interior half of your rooftop air conditioner -- the part you see and interact with every day. When louvers crack, the filter frame breaks, or the original plastic yellows and warps, swapping in a direct-fit Dometic replacement is the fastest way to restore both appearance and airflow performance without pulling the rooftop unit.
Part 3314850.000 is engineered specifically for non-ducted installations. Air is delivered directly into the living space through the ceiling assembly's adjustable vents rather than through a duct distribution system. If your rig uses a ducted ceiling assembly, this part is not the correct replacement.
Manually direct conditioned airflow toward seating, sleeping, or work areas. Louvers pivot to spread or focus the air stream.
Built-in filter media catches dust and pet hair before it reaches the evaporator coil, protecting efficiency and reducing maintenance intervals.
Drops into the same rough opening used by most RV roof vents. Compatible with roof thicknesses from 2 inches to 5.5 inches.
Matches factory appearance and function for over 20 Dometic AC model numbers. Includes mounting hardware -- no additional brackets required.
This ceiling assembly is confirmed compatible with the following Dometic rooftop air conditioner model numbers:
If your Dometic unit is not listed above, verify your rooftop unit model number against Dometic's parts cross-reference before ordering. This part is for non-ducted setups only.
Each package contains one (1) complete ceiling assembly and the necessary mounting bolts. The thermostat and any control wiring are not included. For a compatible wall thermostat, see Dometic Comfort Control Center II part numbers 3314082.011 or 3314082.000, sold separately.
Part 3314850.000 is designed exclusively for non-ducted (free-air delivery) installations. It does not include duct collars, distribution plenums, or duct adapter rings. Do not use this assembly as a replacement in a ducted system without the appropriate duct kit.
Installation requires disconnecting shore power or turning off the AC circuit breaker before any work begins. The ceiling assembly attaches to the rooftop unit through the standard 14-inch by 14-inch ceiling cutout using the included mounting bolts. Roof thickness must fall between 2 inches and 5.5 inches for proper clamping. The control harness connector from the existing ceiling assembly plugs into the new unit -- matching the factory wiring layout on all compatible models.
This ceiling assembly requires a separately purchased thermostat or control module to operate the air conditioner. The assembly provides the air distribution housing, vents, and return air filter -- it does not contain the thermostat circuit. Verify thermostat compatibility with your specific Dometic model number before purchasing controls.
Inspect the return air filter at the start of each camping season and after any extended use in dusty environments. A clogged filter restricts airflow across the evaporator coil, reducing cooling capacity and increasing run time. The filter frame is designed for tool-free removal on this assembly for quick cleaning or replacement.
