Re: No Heay low 20s Help
The first thing I would chect is the propane. Are you able to get a flame on the stove?? If not....
Next would be to see if you are getting a spark when thermostat calls for heat....

I had trouble with mine. Discovered the ground wire vibrated loose.

Re: No Heay low 20s Help
I feel for you, we had so many issues with our SOB furnace.. it was one reason we went to our Sundance. Do you have space heaters? I always carry two of them just in case. I posted an article a while ago about furnaces and their problems. I will see if I can find it. We also had issues with our other trailer and replaced the circuit board after lots of tries to fix it. Good luck, don't freeze.

Any chance the regulator is freezing up? letting enough gas through for the stove top but not enough to fire the furnace. Just a thought.

Re: No Heay low 20s Help
Fred, Does the fan run when you set the T-stat to heat and adjust to sufficient temp to run the furnace? I know this is a basic question, but we need to start some where. I know that you have checked the propane supply, therefore we must assume that if the stove works that you are getting fuel to the furnace. The furnace first goes through a air purge cycle and the 'sail switch' activates the min. air flow so the fuel valve will open. If the fuel valve opens and the fuel doesn't light, then the fuel valve closes. One of several problems could be the min. air flow is not satisfied because of blockage (snow/ice) of the inlet air flue and or the spark ignitor is not working. Hope this helps. I am sure that others will and can give some good advice. Hopefully that something will start working for you folks real soon. No heat and low 20's is no picnic. Good Luck!

There is a feature on the new style OPD valves that will cut off flow if the valve is opened too fast. I experienced it last weekend and fixed it by merely switching tanks. I opened the valve on the second tank and switched to it and everything worked.

Re: No Heay low 20s Help
Where did the wire come loose? At the T-stat or at the furnace? Mine has started working again, (Posted problems in another thread)It works intermittently, which would lend itself to a possible loose connection. Haven't found one yet.
fljlcw,
I went to a Walmart and bought two of these http://www.walmart.com/ip/Sunbeam-Ceramic-Heater/12338793
They had plenty at the store.These work great and along with the FP we can survive w/o the furnace, if necessary. They are also small. Don't take up much space. Good back-up plan for anyone. IMHO Trace

Glad you got it fixed. The only time ours quit working I took a small pin and push the little reset on the thermostat and that fixed it. Got lucky on that one.
