Dometic Refrigerator Roof Vent Kit, Black, Base + Cover
Dometic Refrigerator Roof Vent Kit, Black, Base + Cover — Product description
If your RV or camper's rooftop fridge vent has cracked, faded, or blown off on the highway, this is the fix. The Dometic exhaust roof vent kit gives you a fresh black base and cover for the roof opening above your absorption refrigerator. It lets cooling-unit heat escape while keeping rain and debris out. Fits a roof cutout of 24 by 7 inches or smaller.
Here's the part that quietly does a big job on your rig. The Dometic exhaust roof vent sits on the roof directly above your absorption refrigerator, and it's what lets all that cooling-unit heat climb up and out. A gas or three-way fridge doesn't blow cold air like a household unit. It moves heat, and that heat has to go somewhere. On a lot of RVs and campers, it goes straight up through a roof opening, and this vent is the cap that covers that opening. You get the base and the cover together in one kit, molded in black plastic and shaped rectangular to match the factory cutout.
So why are you here? Usually one of three reasons. The old cover cracked. It faded chalky and brittle after years in the sun. Or it flat out blew off somewhere on the interstate and now there's an open hole on your roof. Black plastic takes a beating from UV, and these covers are consumable. That's normal. The good news is the fix is cheap and straightforward, and replacing both the base and the cover at once means you're not trying to mate a new cap to a sun-baked old base that won't seat right.
This kit is designed for a wide range of Dometic refrigerators, and it fits a roof cutout that measures 24 by 7 inches or smaller. Measure your existing opening before you order. That's the one number that trips people up. If your current vent is a Dometic roof-style unit, odds are good this drops right in. It's the roof exhaust vent, by the way, not the lower sidewall vent. Those are a different part, so double-check where yours mounts before you start pulling screws.
Installing it is a job most owners can knock out in an afternoon. Pull the old vent, scrape the old sealant off the roof, and get the surface clean and dry. Set the new base over the opening, screw it down through the mounting flange, and then run a bead of RV self-leveling lap sealant over every screw head and around the base. That sealant step is the part you don't skip. A roof penetration that isn't sealed right is a leak waiting to happen, and water damage in a coach is no fun to chase down. Once the base is bedded and sealed, the cover goes on top. Done.
After that, the vent mostly takes care of itself. The one thing worth doing is keeping it clear. Leaves, pine needles, and road grime piling up around the vent choke off the airflow, and an absorption fridge that can't dump its heat won't cool the way it should. A quick look every time you're up on the roof cleaning is all it takes. And while this is an RV and camper part first, the same Dometic absorption fridges show up on plenty of boats and camper vans, so if you've got a rooftop fridge vent on the water, this covers that opening too.
One more habit worth building: check the sealant around the base once a season. RV roof sealant shrinks and cracks over time, and the vent flange is just one of several penetrations up there that need eyes on them. If you catch a hairline crack early and lay down a fresh bead, you head off the slow leak that rots a roof from the inside out. It takes five minutes with a tube of lap sealant, and it's a lot cheaper than the repair you're avoiding.
One note on what you're getting: the kit includes the base and the cover. Mounting screws and roof sealant aren't part of it, so grab those separately if you don't have them on the shelf already. But that's it. It's a simple, honest replacement for a part that lives a hard life up top, and getting it back in place keeps your fridge cold and your roof dry.

Frequently asked questions
What does this Dometic roof vent actually do?
It covers the roof opening directly above your absorption refrigerator and lets the cooling unit's heat escape. A gas or three-way fridge moves heat rather than blowing cold air, and on many rigs that heat exits straight up through the roof. This vent caps that opening while keeping rain and debris out.
What size roof cutout does it fit?
It's designed for a roof cutout that measures 24 by 7 inches or smaller, and it works with a wide range of Dometic refrigerators. Measure your existing opening before ordering, since that's the number that matters most for a clean fit.
Is this the roof vent or the sidewall vent?
This is the roof exhaust vent, the one that mounts flat on top of the coach above the fridge. The lower sidewall vent is a separate part. If yours mounts on the side wall rather than the roof, this isn't the right piece.
What comes in the kit?
You get the base and the cover together. Mounting screws and roof sealant aren't included, so plan to supply those. Most owners already have RV self-leveling lap sealant on hand for roof work.
Why did my old cover crack or blow off?
Black plastic covers live in constant sun and weather, and UV makes them brittle over time. They crack, fade, and eventually can let go at highway speed. That's normal wear, and replacing the base and cover together gives you a fresh, properly seating fit.
How hard is it to install?
It's an afternoon job for most owners. Remove the old vent, clean off the old sealant, set and screw down the new base, seal every screw head and the base edge with RV lap sealant, then fit the cover. The sealing step is the one you don't rush.
Will this work on a boat or camper van?
It can. The same Dometic absorption refrigerators show up in camper vans and on boats with rooftop fridge venting, and this vent covers that roof opening. It's an RV and camper part first, so confirm your opening matches the 24 by 7 inch or smaller cutout.
How do I keep it working well?
Keep it clear. Leaves, needles, and grime piling up around the vent block the airflow, and an absorption fridge that can't shed its heat won't cool properly. A quick check whenever you're up on the roof is all it takes.
