Did the 12 volt system work, lights, awning, slide?
Did fridge work on gas did, the stove?

[kjducy]

yes everything worked like a charm except just had no heat...hot water was good...

[kjducy]

so everything was in working condition except the furnace....we were wondering if we needed to do something to get it to work that we may have overlooked...air conditioner operated as should

Stove and fridge worked on LP? Stove burned blue flame?

[kjducy]

we were running everything off electric at the camp site. i didn't use the stove top but we did turn it on to make sure it would start and it lit right up..

Furnace needs propane and 12 volts to work. Sounds like you had propane since burner on stove lit. So 12 volt needed. Battery disconnect needs to be on. Battery needs to have a good charge as furnace can deplete it rather quickly. Did it work on PDI with dealer?

Did the blower fan come on?
And did you hear clicking?

If you get "nothing" from the heater, (ie no fan):

1) Check fuse in power center.
2) Check thermostat (Remove thermostat and connect the heater wire to ground) to see if the heater will start - replace thermostat if it works).
3) Check current limiter located behind grill of furnace. (see photo)

Any further troubleshooting of NO FAN will result in taking the furnace apart and/or electrical troubleshooting with a volt meter.

If this is beyond your capability, you will need to get a technician to help.

I guess it is the switch called "valve sw" in this diagram.
Says it is "N.C." (ie. normally closed)
