Coleman Mach 8430A6301 Center Duct Chill Grille
Coleman Mach 8430A6301 Center Duct Chill Grille — Product description
The Coleman 8430A6301 is the white center duct chill grille for ducted Mach rooftop air conditioners. It sits under the AC and pushes conditioned air front and back through your RV's in-roof ductwork for even cabin cooling. This is the without-control-box version, built to run off a wall thermostat.
If you've got a ducted Coleman Mach rooftop air conditioner and the interior ceiling grille is cracked, yellowed, or just tired, this is the part that makes the cabin look right again. The 8430A6301 is Coleman's center duct chill grille, the white ceiling assembly that sits under a ducted Mach unit and pushes conditioned air front and back through your RV's in-roof ductwork.
Here's what center duct means in practice. Air comes down from the rooftop unit, hits this grille, and gets split straight through the roof ducting to registers up front and out back. That's the classic straight-thru layout on a lot of travel trailers and fifth wheels, and it's why the whole coach cools evenly instead of just the spot under the AC.
This is the without-control-box version. Translation: there are no knobs or switches built into the grille. It's made to run off a wall thermostat instead. So if your rig is wired for a wall-mounted thermostat, this is the grille you want. If you're running an older Mach setup with the control knobs in the ceiling, that's a different assembly, so check what you've got before you order.
Fit is straightforward for anyone who's been under an RV roof AC before. The grille mounts to the ceiling opening below the Mach unit, the ducting connects front and back, and you're back in business. Most folks knock this out in an afternoon. We'd kill the 12-volt and shore power first, always.
Color is white, which matches the standard Mach ceiling look on most coaches. It's a genuine Coleman part, so the fitment and the duct openings line up the way they should. No trimming, no guesswork. If your old grille is brittle or the louvers won't stay put, dropping in a fresh one is one of the cheapest ways to make an older rig feel dialed in again.
