This is the genuine Coleman Mach replacement, part 7330A3231. It senses evaporator coil temperature and cuts the compressor before ice builds up, so your AC keeps blowing cold air on a hot afternoon.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe freeze switch is one of those small parts that does a big job. Tucked into your Coleman Mach air conditioner, it watches the temperature of the evaporator coil. When the coil gets too cold, it opens the circuit and shuts the compressor off for a bit. That's what keeps a sheet of ice from forming across the coil and choking off your airflow.\u003c\/p\u003e\n\u003cp\u003eIf your rooftop AC has been running but not cooling, cycling oddly, or you've spotted frost on the coil, a failed freeze switch is a common cause. It's an inexpensive fix that can bring a tired unit back to life.\u003c\/p\u003e\n\u003cp\u003eThis is part 7330A3231, the genuine Coleman Mach freeze switch. It fits a wide range of Mach models, including the 6797, 6799, 7330, 8330, 8530, 9330, and 9530. Before you order, match the part number on your old switch to be sure. If you're comfortable pulling the shroud and working around the control box, it's a straightforward swap. If you're not, any RV tech can handle it in a few minutes.\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 Mach part 7330A3231, so it matches the original fit and function\u003c\/li\u003e\n  \u003cli\u003eSenses evaporator coil temperature and cuts the compressor to prevent ice buildup\u003c\/li\u003e\n  \u003cli\u003eFits Coleman Mach 6797, 6799, 7330, 8330, 8530, 9330, and 9530 air conditioners\u003c\/li\u003e\n  \u003cli\u003eLow-cost repair for an AC that's freezing up, cycling wrong, or not cooling\u003c\/li\u003e\n  \u003cli\u003eSimple replacement for most RV owners, or a quick job for any service tech\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 the freeze switch do?\u003c\/summary\u003e\n    \u003cp\u003eIt monitors the temperature of your AC's evaporator coil and shuts the compressor off when the coil gets too cold.
