Propane question

[gja1000]

Dear Forum,
I posted about this problem last month, but I have a little more information now, so I thought I'd ask my question again. I have a class C Coachman Freelander 21Q B, new in May 2016. I'm in Texas so it doesn't often get below freezing - but when it does get below freezing, the propane is not getting to my heater and it blows cold air. My gas stove burners will light, the hot water heater is making hot water, but when the temp is below freezing the heater burners will not ignite. When it is above freezing, my heater works just fine, blowing hot air. So does anyone know why the propane is getting to my cooktop and the hot water heater, but not to my heater? Thanks in advance.

The tank is about 1/2 full. Thanks, I will do that.

How full is your propane tank? When there isn't much liquid in the tank it sometimes can't vaporize fast enough to supply a large draw appliance like the furnace. Cold weather makes the problem even worse as it slow down the vaporization process. I'd have the tank filled first and make sure they bleed the air out when they fill it.

Oh yes! I will take it in to be fixed! Being a girl, I always like to have an idea of what might be going on before I take it in. Thank you very much. I appreciate the info!

This could be so many things. Many of the things should be checked out by someone that knows there way around these small furnaces as a propane explosion is not a good thing.

One thing you can do is to examine the line supplying the furnace all the way back where it hooks into the main truck line back to the regulator at the tank. Are there any kinks or major dents?These would restrict gas flow and these points may internally freeze up or constrict in cold weather.

Bear in mind that your furnace needs more gas than your stove and probably your water heater. If your regulator is defective your Furnace may not have enough pressure for the safeties to allow it to light. You can measure this gas pressure but it is only about 10" of water column(NOT PSI) so it is better to get someone with a gauge device that is made for it. The gas pressure in your tank goes down with temperature so the regulator would need to compensate.
