How to stay warm

Outside temps in the 20-30F range is not cold for an rv furnace to keep up with. My furnace keeps me at 70F in -25F temps. However, I do cover the doorway with a H.D. insulated drape. RV doors,can be a leaky cold spot.

When I had the same issue, I moved the lever in the center of my thermostat . It adjusted the cycle time of the furnace allowing it to run longer, giving me more heat. That was my cure and did that in 3 rv's. Simply, pop off the wall thermostats outer plastic cover, they snap in place.


Also, if you have a bug screen cover on the outside vent/exhaust...try removing it to allow optimum air flow.

Make sure the trailers interior return vent is not blocked by something, like a blanket or a box etc.

The "lever" you moved is called the "heat anticipater" adjustment.

In a nut shell the bimetal spring (which is two different metals fused together that have different rates of expansion/contraction) gets preheated by the amount of current running through the spring.

That adjustment regulates the amount of current that runs through the spring.. More current the spring preheats faster opening the contacts faster.. Less current the spring takes longer to open the contacts..

Result is the furnace will run longer or shorter cycles depending on where you set this adjustment.. Downside is you can overshoot comfortable temps easily or furnace short cycles on/off a lot more than it should.

Personally, I recommend ditching that mechanical beast an replace it with a bit more modern digital T stat..



Doing so results in a AUTOMATICALLY CORRECT heating cycle (not to short and not to long, say just right). This also saves a lot in propane..
