Coleman Mach 15 HP2 Non-Ducted Ceiling Assembly, Manual Controls

If you're staring at a broken ceiling unit on your Coleman Mach heat pump and trying to figure out what part you actually need, this is the piece that lives inside your rig. The 9630A715 is the non-ducted ceiling assembly for the Mach 15 HP2 and Mach Power Saver heat pump systems. It's the white interior control box that mounts to your ceiling right below the rooftop unit. It's not the rooftop air conditioner itself. It's the part you see and touch from inside the coach.

Non-ducted means the conditioned air dumps straight into the living space through the ceiling assembly instead of running through overhead ducts to vents around the rig. On a non-ducted setup, this assembly does the work you interact with every day. It pulls return air up through the grille, routes it to the rooftop unit, and sends the treated air back down through the discharge. One opening, one spot, right where you set up camp.

This version comes with manual controls. That means the fan speed and mode switches sit right on the ceiling assembly. You reach up and set it. No wall thermostat to wire in, no digital board to troubleshoot. A lot of owners actually prefer it that way. Fewer parts to fail, and you always know exactly what the unit's doing. If your old assembly had knobs on the ceiling rather than a thermostat on the wall, this is the style you want.

The heat-ready part matters. This is a heat-pump assembly, so it's wired to run your Mach in both cooling and heating. A heat pump works by running the air conditioning cycle in reverse to pull warmth into the coach, which is a lot more efficient than leaning on your batteries or propane on a cool morning. When you're boondocking in the shoulder season, that reverse-cycle heat takes the chill off without much draw. Keep in mind that like any heat pump, output tapers off once outdoor temps drop near freezing. That's normal for the technology, not a fault. Below that, most folks switch over to the furnace.

Fitment is the thing to get right. This assembly is built for the Coleman Mach 480 Series and pairs with the Mach 15 HP2 and the Mach Power Saver heat pump. If your rooftop unit is one of those and you're running a non-ducted, manual-control setup, this is your match. If you've got a ducted system, where the air runs through overhead ductwork, this isn't the right part. And if your controls live on a wall thermostat, you'll want the thermostat-style assembly instead. Check what you're replacing before you order.

Most of the time you're buying this because the old one cracked, the controls quit, or you're finishing off a fresh rooftop install. Swapping the ceiling assembly is a job a handy owner can tackle in an afternoon. You'll drop the old assembly from the ceiling, connect the wiring to the rooftop unit, and secure the new one up against the roof gasket. Kill the power at the breaker first, and take a photo of your wiring before you disconnect anything. If you're not comfortable working around 120-volt wiring, have your RV tech handle it.

The white finish is the standard look and blends in with just about any RV ceiling, so it won't stand out against your interior the way an off-color panel would. It's a genuine Coleman-Mach part, so it fits and functions the way the factory intended, and it carries the full manufacturer warranty. If you're not sure this is the exact assembly for your unit, send us your rooftop model number and we'll confirm the fit before you buy.
