Furnace Problem - Shuts off while on Battery
I have a problem that has just started recently with my furnace. Let me try to do this logically....
Day One Boondocking on 12v Battery power. furnace comes on and operates normally-no problems
Day Two Boondocking - Same as above
Day Three Boondocking Furnace comes on fan runs about 30 seconds and stops - furnace has turned itself off.
Propane is good both stove and reefer working properly
Battery is showing at 75 per cent on meter in trailer (note I dont take this figure literally but it is an indication)
All lights working ok and pump ok - indication is Batt is still charged enough to work.
Last day AM putting in slides Battery has enough power to put both slides in.
When I plug into AC or run my generator with the trailer plugged in the furnace works as it should.
This all kind of points to the battery but is confusing as the battery still has enough charge to bring in the slides but not run the furnace fan?
Is there a voltage switch on the furnace that if it doesnt see enough volts will turn it off?
Also this shutoff occurs right about the time the propane should ignite but it doesnt get a chance. But it ignites on que when plugged into shore power or Gen.
Anybody with any info or guesses out there? Has any one had this scenario before?
