Your RV thermostat serves to help keep you cool during the dog days of summer and nice and toasty during those cold winter months. It can be viewed as the “brains” of your RV’s heating and cooling system. And like many RV components, thermostats have improved over time. Technology has provided them with better control over your RV’s HVAC system. Is it time for you to consider an RV thermostat upgrade?? In this video, we’ll provide an overview of RV thermostats and how modern ones can save you money while keeping you in comfort.

Ask yourself – does your RV have separate thermostats for its heating and cooling units? Is yours an older recreational vehicle? Have you ever had trouble with the thermostat in your RV? If so, you may want to consider an RV thermostat upgrade even if your current one seems to be operating properly.

In this video, you’ll learn some key elements to consider when deciding on an RV thermostat upgrade. It examines situations where an RV thermostat replacement to one that is digital and programmable will ultimately pay for itself.

      Hi Mark. Thanks for visiting the RV Repair Club site and the opportunity to assist with your T/stat question. You can use a residential model, however make sure you get a name brand model as some of the “bargain” versions use weak wire and the solder points can’t hold up to road vibration and temperature changes. Thin gauge wiring also is an issue when temps get really cold.

      Hi, Bud. To provide more specific troubleshooting information we need to know the make, model, and year of your RV as well as the model of thermostat. Some of the older t/stats only controlled the furnace with the air conditioning unit controls on the AC. Newer models control both and can be several brands but if it will not let you go above 32 degree I assume the t/stat is bad? I would recommend replacing it with the same brand as your AC unit or furnace.

    On an AC/Gas Furnace upgrade to a Digital Thermostat is it necessary to also upgrade / replace the relay control box. My A/c rooftop is a Dometic Quick Cool and an Atwood Gas Furnace. Can you do another upgrade video covering this type of upgrade? Thanks.

      Hello Richard,

      That would be good video content as Dometic has over 50 different air conditioning units and you must match the correct thermostat with the Electronic Control Box that is in the air conditioner. Some are 4 button thermostat and others are 5 buttons depending on heat strips and heat pump options as well as zoning. It will be a while before we shoot more content, but will put it into the list. In the mean time, I would suggest getting your model number and serial number and contacting Dometic directly. They also have just introduced a bluetooth single zone and multi-zone thermostat if interested.

      Thanks,

      Hello Larry,

      I would check the voltage going to the thermostat when on battery and then on shore and make sure it doesn’t change. When plugging into an outlet, the converter takes over the 12v system. There could be a problem with the converter but on most newer converters even if it fails the battery would take over. The thermostat will work off of 12v, it just won’t run the fan or AC. The thermostat just sends a 12v signal to a relay in the AC to turn on, it gets the power from 120v when being plugged in. If the thermostat looses all power when plugged in, check the voltage at the thermostat and the converter. If the thermostat has power but nothing operates, you would have to check the wiring at the thermostat and then the appliances. Being a household thermostat it is more likely it has something to do with the wiring, the color codes might be different than RV thermostats.

      I hope this helps!
