Looking for some extra input......I have owned two different RVs now that furnaces do the same (I think silly) thing when out of propane. I think both furnace were "suburban" but I can verify that later if we need to. The heaters work fine when they have propane but the thing that happens when they are out of propane is the blower keeps running and running and running until I shut them down or the coach battery is dead.....Is this normal or is their some type of broken timer or sensor that should shut these completely off if the burner does not light after a cert amount of time???? I understand that they have to run to clear gas if the burner don't light and gas was present but when there is no gas. One time I even turned off the propane (on purpose) and the heater fan never stopped running. It just keep blowing even when I turn the propane back on it never tries to relight it's self. I had to shut it off at the thermostat, wait a few minutes for it to cycle off and then turn it on again before it would light. Is this normal???

Normal and it ALWAYS happens in the middle of the night. Another one of those laws of nature along with "if it tastes good, it's not good for you."

I believe that is normal. Every one that we have owned, acted that way. But, if you are out of propane before the furnace tries to light, it should try 3 times, then shut down.

If the furnace is running when the propane runs out, the thermostat does not know the furnace is out of propane, and will not shut the furnace off until the interior temp reaches the setting on the thermostat.

It is a great feature for freezing your booty off at night. If the first propane bottle is even close to low, I use the second bottle at night.

It is a normal situation for the fan to keep running, but it is correctable by upgrading the OEM ignitor/control board to a Dinosaur Fan 50 Plus board with fan control.

It's normal... your thermostat setting is still calling for heat... thermostat doesn't know you are out of propane. Just turn it off at thermostat or set temp to low setting... 40 degrees.

Thank You All......Switching to the other tank when low don't help on my "A".....I only have one tank and some times I try to "push the bounds of reality" when the tank is low because it is such a pane to take the rig to fill up the tank......That "Dinosaur PC Board fan 50 Plus" looks like just the thing I need to save my batteries....Thanks again.

Some furnaces will continue to run when the gas runs out but many of the newers ones will not. All depends on how the control board is programed. It IS a PITA when they do that though because they can flatten a battery bank pretty quickly.

Yeah, it's normal. I stayed in my class c when I was a dog handler in the Iditarod. It was -23

I got the camper as warm as I could, put on ALL my clothes, turned off the furness and climbed into my sleeping bag. At -23, I didn't want it blowing in cold air all night. As it was, my orange juice was frozen solid in the morning.

That is the reason the automatic propane regulator was invented. It will indicate when one bottle is empty so you never have to run out as long as you check once a day.
