We just bought a new Navion 24J in Ohio Friday, and started driving home to OK. The first night out our propane heater worked until we woke up at 3:00 am and it was about 55 in the coach. The heat would not come back on. So we turned it off, turned on the engine and headed down the road. When we stopped a few hours later to rest, we turned it on and it ran again for an hour or so, then stopped and would not come back on. It is currently working right now sitting in our driveway, but who knows if it will stay on through the night. It's only set on 50, just enough to keep it from freezing inside until we winterized. Does anyone have any ideas before we go in to our local dealer? We are first time motorhomers so I'm sure we have a lot to learn.

My guess . . . the coach batteries have discharged to a level insufficient for the operation of the propane furnace. The furnace control circuitry and the fan motor run on 12 volts which is provided by the coach batteries (when the engine isn't running and you aren't plugged into shore power)

If your engine is running, the alternator will work to recharge the coach batteries, also if you are plugged into shore power, your converter will work to recharge the coach batteries. At the same time either the engine is running or you are plugged into shore power, there will be 12 volts to run the furnace properly even if the coach batteries aren't finished charging.

Congrats on your new rig, by the way. Have fun!

So today we called the service technician who did the pdi on our Navion and he's thinking we had moisture in the propane tank and suggested we get the tank filled and add some methanol. So we did that today. It's parked in the driveway plugged in to shore power, and we will check the heater here in a while. The generator would not keep running either, nor would the heat pump blow warm air, so he thinks that caused all the problems. Will keep you posted on what happens next.
