Rv heater

For members to give you good specifics answers they're going to need the year, make and model of what your RV is (you should put this in your profile) and then it would help them further if they knew the make and model of furnace.

Check to be sure there is no clogged filter or obstructions in the return air duct or output ducts. It's common for a furnace to cycle off due to overheating if it's not getting enough air across it.

Next, I'd swap out the thermostat. You might just take it off the wall and jump the red and white wires together (assuming an RV is the same as a house furnace? - maybe someone can chime in). That sends a constant signal for heat and rules out the thermostat.

Next, you're into the inner-workings of the furnace where a variety of things could be wrong. How long it runs before shutting down may provide some clues.

How long does it run before turning off and needing to be reset? Seconds? Minutes? Heats the trailer once then shuts down? How much propane is in the tanks, how many / big? Did you refill/replace them recently?

Good chance your propane regulator is bad

Really need the heater manufacturer and model to tell much. Also, a better description other than it goes on then off. Are you on shore power or battery?

Mud Daubers clog the intake?

Start trouble shooting from the beginning. Have you just filled propane tanks or turned off the valves and then turned them on, if so, turn them off, wait a few seconds, and turn on oh so slowly. You may need to do this 2 or 3 times to equalize pressure. The last time they are turned on, make sure the propane tank valve is wide open. Some think that just cracking the valve is enough, it may not be, your regulator is there to control flow. Then light your stove top, once all burners are working at once, then turn off and try the furnace. These are the first steps I would take and have taken in the past. It solved the problem more than not over the years.

Are you plugged into shore power? If not then status of battery becomes an issue - heater fan takes a lot of electric juice and if your battery isn't up to snuff then the fan slows down and the sail switch which allows the furnace to run will close.

Or the exhaust?
