I know this is a shop forum but I figuired someone might could help me. During the extremely cold weather we were having I turned the heater on in my 36 ft. camper just to keep things from freezing in case we had some water in the lines after a recent trip. Was called to work and didn't get back for a few days, ran out of propane while I was away. Now the fan won't cut off unless I unplug camper. So I refilled the bottles and turned the heater on but the fan still wont cut off. I guess theres a relay somewhere but honestly I know nothing about camper heaters. I think its located below the stove top or at least there's an air intake. Any help would be great, thanks.

Yeah its central heat, should have mention that but I didn't think about a fuse to reset. I did turn off all the breakers but the fan still ran. Also took the battery loose and still the fan ran, funny. I'll look for a fuse, somewhere. Thanks for the advice
No I think the battery will run the fan,think about dry camping. No way the battery could run the AC, too much load. The battery runs the fan motor for the heat and the lights. If I remeber right the fan would really slow down when I unplugged the electric cord, due to low battery. And now that I thinl about it I had to dissconnect the battery to turn the fan off. I just turn the thermostat up to 70, I'll let it cycle and see if that will reset the system. You got me thinking though, thanks
There shouldn't be a relay, look for the model number under the access panel outside. Do a google search for the manual and check rv.net/forum under tech section, more stuff there than you can shake a stick at. Get a couple of space heaters to use...since it's plugged in anyways.
Thats my plan if I cant get this figuired out. Were at the house right now but planning a trip in a couple weeks. Just check it again, cool air after reaching prper temp in the camper, fan still running, removed the fuse to shut it down. I have no ideal how to determine if its the thermostat or the control panel on the heater? Something like this always happens when we have a trip planned.

There is probably air in the propane line after changing the bottle. Many RV furnaces are set up such that the fan keeps running continuously if unable to ignite.
Turn the thermostat to off and wait for several minutes to see if the fan stops. Then turn up the thermostat and see if it will ignite. If not, turn it off and wait again for the fan to stop. This could take 2 or 3 trys to get the air out of the propane lines. (Lighting the stove top can sometimes help get the air out of the lines.)
If the fan doesn't stop within 5 minutes of turning the thermostat to off, it may be in a lockout mode and require some kind of reset (which would be specific to the furnace.)

RV furnaces are 12v dc units that ony run on 110 because the converter changes the power. The fans are usually controlled by a snap switch thats located on the side of the heat exchanger. There will betwo of them and they are about the size of a quarter. One is the high limit,and one is the low limit.Sounds like the low limit one dumped out on you.
