GE Appliances Ceiling Assembly for Ducted Installations

What is an RV AC ceiling assembly and when do I need one?

A ceiling assembly is the interior portion of your rooftop air conditioner that mounts to the RV ceiling and directs cooled air into the coach. For ducted systems like the GE RARED1A, the assembly routes air through your existing overhead duct network rather than dumping it into a single room. You need a new ceiling assembly when you are installing a fresh rooftop unit, replacing a damaged or yellowed plenum, or converting a non-ducted setup to ducted. If your rig uses a non-ducted layout instead, look at the Dometic non-ducted ceiling assembly with wall thermostat options.

Which GE rooftop units are compatible with this ducted ceiling assembly?

This collection covers ceiling assemblies and accessories built for the GE RARED1A ducted rooftop air conditioner and related ducted GE models. The RAA76 filter kit and RARMC2A control components are matched to these units specifically, so confirm your rooftop model and serial sticker before ordering. If you are running a Coleman ducted system instead, the Coleman Power Saver HP ducted ceiling assembly is the correct match.

What is the RARMC2A and what does it do?

The RARMC2A is the manual control ceiling assembly used with GE ducted rooftop air conditioners. It mounts to the ceiling plenum and gives you direct cooling, fan, and mode control at the unit itself, without a wall thermostat. Choose this option when your installation does not include a wall-mounted control or when you want a straightforward on-unit interface.

How often should I replace the RAA76 filter on a GE ducted RV AC?

Inspect the RAA76 return air filter every 30 days of active use and replace it at least once per season, or sooner if you camp on dusty roads or run the AC continuously in summer. A clogged filter restricts airflow, drops cooling output, and forces the compressor to work harder. Keeping a spare filter kit on hand alongside other rooftop service parts, like a Coleman soft start kit for compressor protection, is a smart move before long trips.
