Coleman Mach 9330-3251 Selector Switch | A/C Part
Coleman Mach 9330-3251 Selector Switch | A/C Part — Product description
This is the genuine Coleman RVP selector switch, part number 9330-3251, for the ceiling assembly on Mach rooftop air conditioners. It fits the 9530, 9370, 9330, 9430, and 9470 models and handles the fan and mode control. When your old switch gets flaky, it's a quick, affordable fix that beats replacing the whole assembly.
If your Coleman Mach rooftop air conditioner has quit responding to the fan or mode setting, the selector switch inside the ceiling assembly is a common culprit. This is the factory replacement, Coleman RVP part number 9330-3251, made to drop into the ceiling control on a range of Mach units.
It fits the 9530, 9370, 9330, 9430, and 9470 model air conditioners. That covers a lot of RVs and campers running the Mach ceiling assemblies, where the selector switch is the control that tells the unit whether to run the fan, cool, or shut off. When that switch wears out or the contacts get flaky, you'll notice the fan won't change speeds or the unit ignores a setting. Swapping the switch is usually a lot cheaper than replacing the whole ceiling assembly.
We like keeping one of these on the shelf for anyone who maintains their own rig. It's a genuine Coleman component, so the fit and the terminal layout match what came out of the unit. There's no guessing whether an off-brand switch will line up or handle the load.
A word on the job itself. You're working around the air conditioner's line power, so cut the breaker before you open the ceiling assembly. If you're comfortable pulling the shroud and tracing the wiring, this is a straightforward swap. If you're not, it's a quick one for an RV tech. Either way, note how the old switch is wired before you disconnect it, and take a photo if that helps.
This listing is for the selector switch itself. It doesn't include the full ceiling assembly, thermostat, or wiring harness, so if your control problem turns out to be somewhere else, check those parts separately. For anything beyond the switch, your Mach service manual has the wiring diagram for your specific model, and it's worth keeping that diagram handy any time you're in there.
