It fits the 8330, 9330, and 8530 series RV rooftop air conditioners. If yours cracked, yellowed, or went missing, this is the factory replacement that drops right back into place.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've got a Coleman Mach ducted rooftop air conditioner, the return air grille is the part you see every day. It's the vented plastic panel on the ceiling assembly that pulls cabin air back into the unit so it can cool it and push it out through the ducts. Over time these grilles take a beating. UV coming through the roof, years of heat cycling, a stray elbow during a bunk climb. They yellow, they crack, and sometimes a tab just snaps off.\u003c\/p\u003e\n\u003cp\u003eThis is the factory Coleman replacement, part number 8330-3951. It fits the 8330, 9330, and 8530 series ceiling assemblies, which are the ducted setups Coleman put in a lot of travel trailers and fifth wheels. If your coach has a ducted Mach unit and the return air pulls through the ceiling grille instead of a wall box, this is almost certainly the panel you're looking at.\u003c\/p\u003e\n\u003cp\u003eSwapping it is about as easy as RV work gets. The grille snaps into the ceiling assembly frame, so most owners pop the old one out and click the new one in without any tools. No wiring, no gas, no coolant. Just line up the tabs and press. If yours has a filter sitting behind the grille, pull and clean it while you've got the panel off. That's a good habit anyway.\u003c\/p\u003e\n\u003cp\u003eOne thing worth saying up front. This is the return air grille only. It's the cosmetic and airflow panel, not the whole ceiling assembly and not the ducted distribution box. If your unit isn't cooling, a fresh grille won't fix that. But if the old one is ugly, brittle, or broken, this brings the ceiling back to looking factory clean. And it keeps airflow moving the way Coleman designed it, which matters more than folks think. A cracked or missing grille lets air short-cycle and can drag down how well the whole system cools.\u003c\/p\u003e\n\u003cp\u003eBuy one if yours is cracked or discolored. Buy two if you've got units front and rear and they're both getting tired. It's a cheap part that makes an old ceiling look new again.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eFactory Coleman replacement grille, part number 8330-3951, matches the original fit and finish\u003c\/li\u003e\n  \u003cli\u003eFits Coleman Mach 8330, 9330, and 8530 series ducted ceiling air conditioner assemblies\u003c\/li\u003e\n  \u003cli\u003eSnaps into the ceiling assembly frame, no tools or wiring needed\u003c\/li\u003e\n  \u003cli\u003eVented panel keeps return airflow moving the way the system was designed to run\u003c\/li\u003e\n  \u003cli\u003eEasy access to the return air filter behind it for cleaning while the grille is off\u003c\/li\u003e\n  \u003cli\u003eBrings a yellowed or cracked ceiling panel back to factory-clean looks\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Coleman reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhich Coleman Mach units does this grille fit?\u003c\/summary\u003e\n    \u003cp\u003eIt fits the 8330, 9330, and 8530 series ducted ceiling air conditioner assemblies.
