Heater issue on 2011 341 while generator is running.

[Phantom341]

Hello fellow Georgetownians. I just got home from a three day dirt bike riding trip to Stonyford, Cal. If your a serious dirt biker and would like to ride for three days without seeing the same place, than Stonyford is the place to go. Anyway, I was dry camping and the nights got into the low thirties. I set the main thermostat for 65 and it kicked on and worked great until the coach batteries ran low. I turned on the generator to charge the batteries and the front A/C unit kicked on. I let it run for a few minutes just to see if anything would come of it but it just blew cold air. I turned the thermostat to the "off" position and ran the generator until the battery control panel read 2/3. I turned the generator off and turned the heater back on. It ran perfect. Has anyone had a similar issue or know what could be wrong?

So if u are going down the road and need heat from the furnace u don't have to run the generator

Unless the thermostat was set to Auto for fan operation, the a/c fan will run when there is 110v power. It may be that the air cond was not actually cooling, just the fan kicking up air.

What Bill said. If you have 110 VAC, and the air cond fan is set to low or high it will run constantly. If you set the fan to auto, the fan will come on when the furnace cycles in order to circulate the warm air. Note: the air coming out of the roof air conditioner will not be warm. It's just MOVING is all it's doing.

ohiobill and Ovair, thanks to both of you. I set the main thermostat to auto, turned on the generator and heater and the fan did not turn on.

I wish the genious that did my walk through with me knew half as much as the fellow forum members.

Unless there's something built into the new thermostats, I have to disagree with your statement of setting fan switch to auto and the it will come on when the furnace cycles in order to circulate the warm air. They installed ductwork in the flooring to do that. The fan switch should only operate when the thermostat is set for AC or Heat Strips. Otherwise it is not connected to the Furnace is any way. It will cycle the fan On & Off when set at Auto with the AC or Strip Heater setting. If set to On it will run non-stop as long as there is a 120 volt source. I know the analog t-stats operate as I described. Mow the new Digital T-stat might have a offset temperature setting for the fan but it defeats the purpose of running the heat as the fan moving the air cools the air resulting in the furnace never keeping up.

I have a 2011 Georgetown 300 and I have the same problem with a/c fan when you run heater, but only when plugged into 110v power. I don't have auto setting on my thermostat. The factory said the thermostat is bad? Waiting for dealer to replace it, may or may not fix problem.

I posted about this problem as well. Turning the t-stat fan setting to Au solved the problem for me. When using the generator or plugged into 110v, the AC does fan does not turn on at all. Just the propane heater and fan, blowing air through the floor vents. I was in the desert last weekend riding and it got quite cool. There were several occasions when I had the genny on with the heater. The AC never kicked on.

Dealer showed me how to reset thermostat to auto, problem solved

I am so glad that my 2011 360 has the manual stat...not headaches.
