Furnace and AC

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.

TT

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.

The fridge was all ready cooled when I started.

Originally posted by gappman FYI...I tested the fridge using 12 volt only and it ran for 8 hours on a single battery before depleting.

Was the fridge pre cooled, or did you start from a warm box, and was it full or empty? A full precooled fridge will only cycle so often, rather than running full time when trying to cool a bunch of warm stuff..

Originally posted by dsmiths I have been told its dangerous to have the fridge on propane instead of 12 volts when towing due to the possibilty of being in an accident and having a gas leak.
