It reads cabin air temperature so your rooftop air conditioner cycles to the setting you dialed in. A simple, low-cost replacement part when the original sensor fails or you want a black finish to match your thermostat.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf your Coleman Mach thermostat isn't holding temperature right, the room sensor is often the culprit. This is the black 6537-3191 replacement sensor built to work with Coleman Mach thermostat systems. It's the small component that actually measures the cabin air, then tells the thermostat whether to call for cooling or heat.\u003c\/p\u003e\n\u003cp\u003eWe see these fail after years of RV vibration and temperature swings. When they do, the AC either short-cycles or runs well past your set point. Swapping in a fresh sensor usually sorts it out. It's an inexpensive part that makes a real difference in how your rig holds a comfortable temperature on a hot afternoon.\u003c\/p\u003e\n\u003cp\u003eThe black finish matches darker thermostat trim and interior panels. If you're running a Coleman Mach rooftop unit and chasing down a comfort problem, this is a cheap, sensible first thing to check and replace.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eReads cabin air temperature so your Coleman Mach thermostat cycles the AC accurately\u003c\/li\u003e\n  \u003cli\u003eDirect replacement, part number 6537-3191, for Coleman Mach thermostat systems\u003c\/li\u003e\n  \u003cli\u003eBlack finish matches darker thermostat trim and interior panels\u003c\/li\u003e\n  \u003cli\u003eLow-cost first fix for short-cycling or inaccurate temperature control\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 sensor do?\u003c\/summary\u003e\n    \u003cp\u003eIt measures the cabin air temperature and feeds that reading to your Coleman Mach thermostat, which decides when to run the air conditioner or heat.
