Are you running on 12v, or 110? I know on mine, if the battery gets low while dry camping, the furnace won't work. Also, make sure there isn't any wasp nests in there around the burner area, or the gas won't fire up. Can you hear the auto striker trying to light the pilot? You should hear a series of clicks, when you first turn it on. If not, the fuse may be tripped. Also, it bears a mention, verify that you do have enough gas! Good Luck! Randy

If you are turning on the thermostat and not hearing the fan start
immediately then it's loss of power or the thermostat is not
turned up high enough to come on.
Does your thermostat have a cool/heat/off setting??
Of course you have it in heat mode right???
Turned all the way up to as hot as it will go right???
Check for blown fuse in the fuse box labeled furnace.
Lack of LP gas and a wasp nest might keep it from lighting but my
fan comes on immediately when the thermostat is calling for heat.
If you have no fan, it's more basic than LP gas or wasps.

Good luck!

We had a lady on another chat group who asked the same question
just last month.
It turned out her thermostat wasn't calling for heat.
She pulled off the cover and tapped the switch with a finger
and it came on!

Furnance trouble

I have turned heat all the way up, in heat mode, checked lp tanks, checked fuses and still nutting. AC works great, fan mode works great just need to get furnance working "AGAIN".. thanks for the words of advice.

You still haven't said if the furnace fan starts when you kick
on the thermostat.

I'm not talking about having the fan in On mode.
I'm talking about having the fan switch in "auto" mode and
when you turn up the thermostat does the furnace fan
start immediately?

If you haven't done so take the t-stat off the wall and check to be sure that all the wires are still connected. Vibrations and low voltage t-stat wire most likely 20 or 22 gauge could have broke off or just came off from the terminal. The wires are not secured within the wall so they can move around as you travel down the road.

Last year we ran into a problem with our furnace where the the fan would kick on but we would get no heat. I knew that both tanks were recently filled. I scratched my head and ended up turning the current LP tank being used off and switched over to the other tank and it worked. It was kind of weird in the way that other appliances would work with the first LP tank except the furnace. Our rig had to go back to the Rockwood plant for some warranty work and they ended replacing the regulator and everything now works correctly.
