coachmac9 Posted September 16, 2015 Report Share Posted September 16, 2015 How hard is it to change out the original thermostat to a new thermostat that actually works? We have a 98 Fleetwood Discovery DP with dual AC's. Don't have the make or model with me right now but was just wondering if this is something I can do. I am fairly handy at doing other electric projects such as wiring new plugs, adding a breaker to a breaker box ect ect. Link to comment Share on other sites More sharing options...
Daveh Posted September 16, 2015 Report Share Posted September 16, 2015 I know it has been done and there may be threads on the subject on this board if you do a search and otherwise do a general web search re rv thermostat and you will find material. I have researched it before but did not keep any links. Generally you can switch them and many do switch over to digital thermostats which tend to hold the temp in a more precise temp range. Get your make of AC and then check out some of the camping equipment sites. People have also switched over to regular residential thermostats which can be lower cost. The trick there is to get the wiring right since the color codes for the wires may not be compatible. I know that when I did my search I found where RV owners who successfully made the change posted wiring schematics. If you get more info re your make others on this board may be able to help also. dave Dave and Lana Hasper Link to comment Share on other sites More sharing options...
LFDR3116 Posted September 16, 2015 Report Share Posted September 16, 2015 When we replaced ours, we did an online search for the make/model with info off the thermostat, and replaced with the same. No changing around of anything needed. Just rewire on same as the on that came off. Pat DeJong Link to comment Share on other sites More sharing options...
TXiceman Posted September 16, 2015 Report Share Posted September 16, 2015 If you have the thermostat that controls, BOTH A/C units, it is pretty difficult. If they are separated, you can change to a Hunter. Do a Google search or on this site for Hunter RV thermostat.

Dutch_12078 Posted September 17, 2015 Report Share Posted September 17, 2015 I replaced the two Duo-therm analog heating and A/C thermostats in our coach with Honeywell digital programmable stats. The wiring was pretty easy, and I added a mini-toggle switch to each stat for the 2-speed A/C fans. As said though, if you have a single two zone thermostat, the conversion would be quite complex.
