{"product_id":"coleman-mach-9430-4552-non-ducted-ceiling-assembly","title":"Coleman Mach 9430-4552 Non-Ducted RV AC Ceiling Assembly","description":"\u003cp class=\"nvn-hero\"\u003eThe Coleman Mach 9430-4552 is the non-ducted ceiling assembly that mounts to your RV ceiling underneath the rooftop unit. It's the part you see and adjust every day: the return air grille, the discharge louvers, and the wall thermostat wiring. Fits the Roughneck, Mach 15, Mach 3 Plus, Mach I, Mach III Power Saver, and Mach 8 lines. Control box sold separately.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eHere's the simple version. If your Coleman Mach rooftop air conditioner blows cold air straight down through a single grille right below the unit, you've got a non-ducted system. The 9430-4552 is the inside half of that setup. It's the ceiling assembly that bolts up to your RV's roof opening underneath the rooftop AC, and it's the part you actually see and touch every day.\u003c\/p\u003e\n\u003cp\u003eThis is the wall thermostat version. That means the assembly itself doesn't carry the temperature knobs or the mode switch. Instead, it's wired to work with a Coleman Mach wall thermostat mounted somewhere in the coach, so you set your temperature from the wall like you would in a house. A lot of newer rigs are built this way because it's cleaner and easier to read than reaching up to a ceiling dial. If your coach was set up for wall thermostat control, this is the assembly that matches it.\u003c\/p\u003e\n\u003cp\u003eOne thing to know before you order. The control box is sold separately. On a non-ducted Mach system the control box is the brain that ties the rooftop unit, the ceiling assembly, and the wall thermostat together. Some folks replacing just a cracked or yellowed ceiling assembly already have a good control box up there and only need this piece. Others doing a full refresh will want to price the control box at the same time. If you're not sure what you've got, pull the assembly down and check for the control box before you buy.\u003c\/p\u003e\n\u003cp\u003eFitment covers a wide swath of the Coleman Mach lineup. This assembly is listed for the 48203C9665 series Roughneck, the 48204 series Mach 15, the 48203 series Mach 3 Plus, the 48207 series Mach I, the 48208 series Mach III Power Saver, and the Mach 8 Rooftop and Mach 8 CUB Rooftop units. That's most of the popular non-ducted Coleman-Mach rooftop air conditioners you'll find on travel trailers, fifth wheels, and motorhomes. Always match the part to your specific rooftop model before installing.\u003c\/p\u003e\n\u003cp\u003eWhat does the ceiling assembly actually do? Three things. It holds the return air filter that keeps dust and lint out of the evaporator up top. It gives you the adjustable louvers that aim the cold air where you want it, front of the coach, back, or spread out. And it houses the wiring connections that link down to the wall thermostat. When any of those parts get brittle, cracked, or just plain ugly after years of sun and road vibration, swapping the whole assembly is usually cleaner than trying to patch one broken tab.\u003c\/p\u003e\n\u003cp\u003eInstall is within reach for a handy owner. You're working from inside the coach on a ladder, dropping the old assembly, transferring or reconnecting the low voltage wiring, and bolting the new one to the same roof opening. Kill the power at the breaker and the battery disconnect first. Take a photo of the wiring before you pull anything apart. And don't overtighten the mounting hardware, because the foam gasket up top needs even, gentle pressure to seal against the roof, not brute force.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anyone chasing down a rattling, cracked, or sun-faded non-ducted ceiling assembly on a Coleman Mach unit that runs off a wall thermostat. It's a maintenance and restoration part more than an upgrade. If your AC still cools fine but the interior trim looks rough or a louver snapped off, this brings the inside of the system back to right without touching the rooftop unit itself. Just remember the control box line item if you need that too.\u003c\/p\u003e\n\u003cp\u003eA couple of tips from the shop. Before you climb the ladder, have your replacement return air filter ready, because a fresh filter is cheap insurance and it's the easiest time to swap it. Keep the old hardware bagged and labeled until the new assembly is fully seated and tested. Then run the unit for a few minutes off the wall thermostat and confirm the louvers open, the air moves, and nothing rattles against the ceiling before you call it done.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eNon-ducted ceiling assembly, mounts inside the coach directly under the rooftop unit for straight-down cooling\u003c\/li\u003e\n  \u003cli\u003eWall thermostat control, no knobs on the assembly itself so you set temperature from a wall-mounted thermostat\u003c\/li\u003e\n  \u003cli\u003eFits Coleman Mach Roughneck (48203C9665), Mach 15 (48204), Mach 3 Plus (48203), Mach I (48207), Mach III Power Saver (48208), Mach 8 and Mach 8 CUB rooftop units\u003c\/li\u003e\n  \u003cli\u003eHolds the return air filter that protects the rooftop unit's evaporator from dust and lint\u003c\/li\u003e\n  \u003cli\u003eAdjustable louvers direct cold air to the front, back, or across the coach\u003c\/li\u003e\n  \u003cli\u003eManufacturer part number 9430-4552 from Coleman RVP for a direct factory-match replacement\u003c\/li\u003e\n  \u003cli\u003eControl box sold separately, so you can replace just the assembly if your existing control box is good\u003c\/li\u003e\n  \u003cli\u003eBolts to the existing roof opening for a straightforward inside-the-coach swap\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\u003eIs the control box included?\u003c\/summary\u003e\n    \u003cp\u003eNo. The control box is sold separately.
