This is the genuine Coleman replacement, part 9430-3431, that controls both the heat and cool functions on Coleman Mach systems. Swap out the dead control and get your RV's climate back under your thumb.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Coleman Mach heat\/cool wall thermostat, part number 9430-3431, is the genuine replacement control for Coleman Mach RV air conditioning systems. It runs both the heat and the cool side, so you set the mode, dial in the temperature, and the thermostat does the rest. If the old control on your rig has gone dead, gotten flaky, or just won't hold a setting anymore, this is the part that brings it back.\u003c\/p\u003e\n\u003cp\u003eWho needs one? Usually it's an RV owner whose original Coleman Mach wall thermostat has quit after years of service. Heat, road vibration, and the odd power surge all take a toll on these controls. When yours stops talking to the air conditioner, you're stuck either running the unit blind or sweating it out. A fresh thermostat is the cheap fix that gets your climate control back.\u003c\/p\u003e\n\u003cp\u003eIt's built for Coleman Mach air conditioners, so before you order, do yourself a favor and check the part number on your current thermostat against 9430-3431. Coleman has built several different wall controls over the years for different setups, and they aren't all interchangeable. If the numbers match, you're good. If you're not sure what you've got, send us a photo of the back of your old control and we'll help you sort it out.\u003c\/p\u003e\n\u003cp\u003eOne honest note on the heat and cool part. This thermostat commands both the cooling and the heating functions your Coleman Mach system already supports. It doesn't add heating your air conditioner doesn't have. So if your setup is cool-only, the heat side simply won't have anything to talk to. Match the thermostat to what your rig is actually wired for and you'll be set.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward if you're comfortable matching wire for wire to the old control, but it's low-voltage work and the terminals have to land in the right spots. If wiring isn't your thing, any RV tech can swap it in a few minutes. Take a photo of the existing hookup before you disconnect anything, and you'll thank yourself later.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eGenuine Coleman replacement thermostat, part number 9430-3431\u003c\/li\u003e\n  \u003cli\u003eControls both heat and cool functions on Coleman Mach RV air conditioners\u003c\/li\u003e\n  \u003cli\u003eDirect replacement for a worn, dead, or flaky Coleman Mach wall control\u003c\/li\u003e\n  \u003cli\u003eWall-mount design for the RV living space\u003c\/li\u003e\n  \u003cli\u003eSet the mode and dial the temperature, the thermostat handles the rest\u003c\/li\u003e\n  \u003cli\u003eBacked by the Coleman manufacturer warranty\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\u003eWhat does this thermostat control?\u003c\/summary\u003e\n    \u003cp\u003eIt controls the heat and cool functions on Coleman Mach RV air conditioning systems.
