So I have yet to run our heater in our new (bought last Saturday) but after looking at the thermostat it appears there is no way to adjust the temp?I'm new to RVing so I'm not quite sure what I'm supposed to be seeing as far at temp control?There doesn't appear to be any way to adjust it, like the lever is broken???the little black lever seems to be stuck to the thermostat, as in it won't move at all. I feel if I force it I will snap it off. Does this look correct or should there be more to the thermostat. Sorry for the 20q's just trying to make as few mistakes and learn as much as I can.thank you in advance for your help.

You have to force the top lever in order to activate the thermostat. Then use the bottom lever to select the temperature.

by a new one this one is shot. the lever should move side to side and there should be a little arm that moves with it to show the temp you want. I can't remember the name of the one at wal mart everyone buys. maybe some one else will chime in and give the name.

I know mine felt the same way..I had a little switch for on and off for the furnace that felt like i was going to brake it every time i switched it..Take that analog thermastat off its really easy and put up a digital non program thermastat for 25 bucks..It reads the temp easier and regulates it better

https://www.walmart.com/ip/Honeywell-RTH111B1016-U-Digital-Non-Programmable-Thermostat/22002683

so even though this is a heat only thermostat (since we have a window style unit for AC) I can use an off the shelf digital thermo?if so that's cool. I would rather have digital.

Great ... what model? - so others will know what to look for. :)

Interesting ... it would seem what you bought is a Honeywell RTH111B1016/U but in the reviews it says this model does not have a back lit display. Just wondering?? :h

I posted a thread about the exact same problem on our new tt last spring. The arm was stuck and wouldn't move. I eventually figured out if I pulled it forward a little while trying to slide it, it freed up.

The best thing anyone can do with those Dometic thermostats is remove it and throw it as far as you can into a canyon where nobody else can get to it. Those things have been put into trailers for many years and are as cheap as they come. They are very inaccurate. There is a heat anticipator calibration dial inside that will help. The best guess is to move the arm to about half scale then temperature swings will not be as great.

Awesome!

I picked one up on the way in to work and will be installing it later tonight.

Thanks again for all the suggestions and help!

Sure. The A/C in my Coachmen is direct blow with it's own controls so the stock bi-metal thermostat controlled just the furnace. I replaced it with this non-programmable Honeywell RTH5100B digital thermostat which controls temperature swing much better. I like this one in particular because it has a back lit screen that lights up anytime I push a button, making it quite easy to see. :B
