A direct-replacement analog thermostat for Coleman Mach RV air conditioners. No programming, no touchscreen, no complexity -- just a straightforward dial control that keeps your rig cool. Ideal for owners who want a reliable, budget-friendly thermostat that does exactly one job well.
The Coleman Mach 7330-3861 is a factory-style analog thermostat built for cooling-only operation in RVs equipped with Coleman Mach air conditioning units. It runs on 12V DC from your RV's electrical system and uses a classic rotary dial to set your desired cabin temperature -- no batteries, no apps, no firmware updates required.
This is a single-stage thermostat, meaning it sends one signal to your A/C unit: on or off. It does not control heat strips, a furnace, or a heat pump. If your Coleman Mach unit is a heat-cool model and you want full heating control, you will need a different thermostat. But for campgrounds, seasonal use, or any setup where cooling is all you need, the 7330-3861 is a clean, dependable solution.
Rotate to set temperature. No touchscreen, no menus, no learning curve. Works the first time, every time.
Dedicated cooling control for Coleman Mach A/C units. Clean wiring, simple operation, nothing to configure.
Powered directly by your RV's 12V system. No separate power supply or AA batteries needed at the thermostat.
Replaces the original thermostat on many Coleman Mach rooftop A/C units. Matches the factory wiring harness connector.
This thermostat manages the compressor and fan on a single-stage Coleman Mach cooling unit. When the cabin temperature rises above the dial setting, the thermostat signals the A/C to run. When the set temperature is reached, it cuts the signal and the unit stops. Fan-only mode (if available on your A/C unit) may also be selectable at the thermostat depending on unit configuration.
This thermostat is explicitly a cool-only unit. It will not activate electric heat strips, a gas furnace, or a heat pump, even if your air conditioner chassis supports those features. If your RV has a Coleman Mach heat-cool system or a Mach 10 NDQ/HP unit and you want thermostat control of both heating and cooling, you will need a two-stage or heat-cool thermostat instead.
If you want to add WiFi or Bluetooth app control to your Coleman Mach system, the Micro-Air EasyTouch 352C is a popular drop-in upgrade that uses the same low-voltage wiring and adds smartphone scheduling, remote monitoring, and multi-zone capability. Available in black or white.
