Your RV thermostat serves to help keep you cool during the dog days of summer and nice and toasty during those cold winter months.

    i replaced my Duo-Therm thermometer and I installed a Honeywell RTH5160D1003 digital thermometer works fine on 12 volt but stops once switch over to shore power.

      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!

    i need help with new rv domestic roof top air conditioner from control board to new domestic digital thermostat


    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.

    Thermostat in my RV will not allow me to raise temp above 32 however I can lower the temp. Fix? Replace? Please your recommendation Thanks

      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.

      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.
