Dometic RV Air Conditioner Accessories

What Dometic RV air conditioner accessories do you carry?

This collection covers 105 replacement parts and accessories for Dometic and Duo-Therm rooftop AC units, including control boxes for the Brisk Air II, vent deflectors, ceiling assemblies, thermostats, capacitors, fan motors, and shroud covers. If you need a complete ceiling assembly for a non-ducted setup, see the Dometic Ceiling Assembly for Non-Ducted installations with Wall Thermostat or the FreshJet 5 with Heat Pump ceiling assembly.

How do I find the right part for my Dometic or Duo-Therm AC?

Start with the model number and serial tag on the AC chassis or inside the ceiling assembly. Dometic and Duo-Therm parts diagrams are organized by base model (Brisk Air, Brisk Air II, Penguin II, FreshJet), so matching that model to the exploded view is the fastest path to the correct control box, board, or capacitor. Confirm the model number before ordering to avoid a return. If you need a second set of eyes, text or call 817-984-1852.

Will these parts fit older Duo-Therm units?

Many of them will. Duo-Therm is the legacy brand name for Dometic rooftop AC units, and most current Dometic service parts carry forward to Duo-Therm Brisk Air, Penguin, and Comfort Control models. Each product page lists OEM cross-reference numbers and superseded part numbers so you can verify compatibility against the part stamped on your existing component.

Do you carry other RV electrical and adapter parts?

Yes. Beyond AC components, we stock surge protectors, converters, and shore power gear in RV Electronics, plus 30A and 50A RV Plug Adapters for campground hookups. Free shipping on orders over $100.
