Furnace / regulator problem
Hi, another newbie, so please bear with me.
I just purchased a 2006 Country Coach Inspire 360, 40' MH.
When the weather is cold and I light the furnaces, they run for a short period, then shut off. The blower comes back on and they try to relight, to no avail. When I turn the stove on, the 3 burners light, burn for several minutes, then go out. Looking at the regulator, it is frosted completely over. Let it sit until it warms up and they both light and run, stove remains lit. Thought I read in the CC manual, that if there is a leak, the furnace will shut off the gas supply. Any help would be appreciated! Thanks.
