Coleman-Mach 9430A3422 Cool-Only RV Thermostat 12V
Coleman-Mach 9430A3422 Cool-Only RV Thermostat 12V — Product description
The Coleman-Mach 9430A3422 is a single-stage, cool-only wall thermostat for RV air conditioning. It runs on 12-volt DC power, shows your set point on a clear digital readout, and finishes in black to blend with most RV interiors. Simple controls, no heat function, just straightforward cooling.
If your RV runs a Coleman-Mach cooling-only air conditioner and the wall control finally quit, the 9430A3422 is the replacement that keeps things simple. It's a single-stage, cool-only thermostat with a digital readout, and it runs on 12-volt DC power straight off your rig's house system. No heat mode to fuss with, no heat pump logic. Just set the temperature you want and let the air conditioner do its job.
Single stage is exactly what it sounds like. The thermostat calls for cooling, the compressor runs, and when the cabin hits your set point the unit cycles off. That's the whole story. For a lot of travel trailers and motorhomes with a straight cooling rooftop AC, that's all you need. The digital readout takes the guesswork out of it too. You see the actual set temperature on the display instead of squinting at a slider or a dial, which matters on a hot afternoon when you just want the coach cool before you climb in.
The black finish is a nice touch if your interior trim leans dark, or if you're matching other black switches and controls on the wall. It's the familiar Coleman-Mach wall control format, so if you're swapping out a tired, unresponsive thermostat, it fits right into the same control setup your rooftop unit already uses.
Who's this for? Anyone with a cool-only Coleman-Mach rooftop setup who wants a clean, digital replacement control. It's popular with folks refreshing an older coach or fixing a control that's gone unresponsive. And because it's 12-volt DC, it ties into the same low-voltage wiring your RV already uses for the AC control circuit.
A word on what it isn't. This is a cool-only control, so it won't run a furnace or a heat pump. If your system has heat, you want a heat/cool or heat-pump thermostat instead, not this one. Match the control to the equipment you've got and you'll be set. If you're not sure which control your air conditioner needs, check the model of your rooftop unit before you order, and reach out to our crew, we're happy to help you get the right part the first time.
