Question Temps dropped now heater won't ignite

I'm here in SE Pennsylvania where temps dropped to about 10 degrees overnight. Heading to Florida tomorrow and of course the heater won't ignite this morning maybe someone has some advice:


Details:[*]2016 FR3 30DS[*]Heat has worked fine since Sunday when it came out of storage[*]Have plenty of propane and I can light the stove[*]Have plenty of juice from the batteries[*]Blower fan comes on and can hear the igniter clicking outside, also smell the propane outside

I have the engine running and put a small space heater inside to help start warming things up.

anything else I can do or I just have to wait for the temp to rise?

You say "plenty of propane I can light the stove"

Light ALL burners at the same time and try lighting the furnace while watching the flame size on the burners. Do you still have plenty of propane?

When it is this cold it's hard to get enough vapor to run big LP user items like the furnace.
Did you try the water heater on propane with the stove burning?

I got a tank warmer blanket. Heats tank and no problem with pressure now. Also uses more of what's in the tank in cold weather. Bought on Amazon.

Works great. Reason I got one, at work we ran blowers with generators and the tanks would start freezing up. By putting the tank next to the hot exhaust, we could get a day from a tank rather then change them out!

in a pinch, if you have 110 volts, use a regular heating pad, like for your back.

I had to heat the gas detector valve on my Georgetown to get the furnace to light! Used a electric heat gun and took about 2 minutes in 0 degree weather! It is the small valve with 2 wires to it just to the right of the white box which has the regulator under it! Good luck!

the propane regulator, or the furnace temp sensor, can be frozen over where they can't sense the propane and don't allow the ignitor to spark - you might could use a lighter or match and hold it to the spark ignitor for a while - then try the furnace again.

I was having trouble getting mine to fire twice. I learned on this forum that you may have to cycle your furnace a half dozen times to push the propane through the furnace valve. I turn it on and wait till blower stops. Turn it off and try again and again. Usually happens when I have gas off for a while when traveling. I tried it and that worked for me. Good luck... It's in 70- 80s in Fl so there is a light at the end of your travel plans.

propane vaporizes at -44 ...any thing run on a camper needing gas will run just fine in weather above freezing...no need to heat the tank....if you need to to heat the tank to make it vaporize to run something you need a bigger tank or check reg. pressure
