I just returned from a fishing trip on the Upper Arkansas river in Colorado.  I could not get my furnace to work on 110 volt shore power.  When I returned home, I checked it on battery only out of curousity and it worked.  Should the furnace also work on 110?

The furnace should work on both 12 volts and 110. the pods internal battery charger keeps the battery charged when plugged into 110. there is nothing to switch or change. I can't understand why it would not work while you were plugged into an outside 110 volt source. did the interior lights work ? did other electrical items work ? there is a possibility the breaker on the 110 source was tripped and the battery voltage was too low to function the furnance igniter.

Everything 110 related worked fine - that is the microwave, tv, radio.  I did check the fuse for the furnace and it was fine as well.  Thanks for the tip.  Guess I will take it to my rpod dealerSmile

I don't know that this is the case, but the furnace fan may work only on 12v power.  You didn't disconnect your battery while you were on 120 shore power did you?  My theory is that shore power would keep your battery charged and therefore the furnace blower would keep going but the actual juice for the fan might be pure 12v.  If that's the case, the fan wouldn't work and the furnace wouldn't ignite if you disconnected the battery for some reason.  I don't know why anyone would do that though.  Maybe they'd figure they had shore power, didn't need the battery, so they took the battery out to use on the boat....  WAG.

Yes the furnace only workes on 12 volts.
If you want something done right, do it yourself.

While the furnace only works on 12v, it has 12v ANYTIME the trailer has 110v, unless there is a problem with both the converter/charger and the battery.

The question is, did all the other 12v stuff work? Lights, water pump, Fantastic Fan, Fridge on 12v?

All good points!  No, I didn't disconnect the battery. Yes, the lights, fantastic fan and fridge all worked on 12 volts.  Just the furnace fan didn't work and the furnace didn't ignite.  Ketelsen campers in Wheatridge, CO suggested that the converter fuse may be blown, but I didn't discover that either. 
Guess I will take it into Ketelsen and see if they can figure anything out!
Thanks for all the great input!  This site rocks!!

OK.. gas was turned on...? Bottles not empty??

Did you use the cook top or water heater on gas?

If it has been a while since any gas appliance has been used, then the lines may need to purge.. the heater is usually the farthest away from the supply, and takes the longest. Also, unlike the cook top, if it doesn't ignite in a set period, it stops trying.. whereas you can stand there with the cook top  knob on and let the line purge until it ignites.. or you burn your fingers holding a match.. (I use one of those long bic lighter thingies) The gas water heater will also error out and stop trying if no flame is detected in a certain amount of time.. (so what I am saying is.. go out to the camper and light the burners.. then try to light off the furnace...)

(BTW, almost no one uses the propane heat if they have hookups.. we use a small ceramic heater, quieter, and cheaper)

Totally agree with elec htr if one needs it for an extended period of time. I usually sleep cool, then like to heat for a short period in the a.m. just to knock the chill down.
Yes, I had cooked on the stove, H2O htr was on elec this time, as was the fridge.  I believe the lines had been fairly well purged of any air.  Also, the blower should turn on immediately (it does on batt power), but no fan, no click-click-click of igniter trying to ignite.
Still a mystery to me.
Thanks for your ideas, though!!

Yes, very odd.  Even with no propane you are right the fan should immediately turn on - on 120 or 12 volts.
