Rear furnace in 2011 Georgetown

[akoldtimer]

Rear furnace will not come on. Air conditioning system is working fine, but when I move the control switch to heat, nothing. Suggestions?

Also, front units are both working fine. Manual that came with the rig not too helpful. Doesn't even let me know where to start looking for rear furnace, unless they're both behind the same cover box outside.

What model is your 2011, mine's a 300. Both front??? There's only one in mine, and I'd bet yours too!! Look for the front furnace. They're one and the same. If the front has reached its set temp and the rear has not, it should keep running providing heat until it's set temp is met. You have to make sure the fan is set to run automatic. And the rear thermostat is set up correctly.

It's just struck me, are you considering the chassis heater that runs off the motor as a front unit? The furnace is separate.

My 2011 only has one furnace and it is controlled by the front thermostat. The rear thermostat does nothing on heat.

What model do you have? Please take a picture of both thermostats and post them here. My rear thermostat does run heat/ ac for the bedroom and maybe the bathroom. While the front thermostat does the same for the living area and kitchen.

350. I don't have pics but both thermostats are identical. How many furnace outputs do you have on the outside of your camper? That will tell you if you have one or two furnaces. When you say "heat" and you are referring to heat strips on the A/C units vs the furnace then you may have those on both front and back.

We have a 378 which does have a front and rear furnace, if I remember correctly it was the only model that had 2 furnaces. May be incorrect on that as it's been 6 years since I compared models.

Furnace outputs outside?? I don't understand what you're saying. I know I only have 1 furnace. No heat strips in my rig. Each thermostat when set correctly will produce heat thru the appropriate vents. I'm assuming my heat comes thru floor registers while AC is thru ceiling vents. It's been since last Oct that we used heat. But then i didn't know how to set my thermostats correctly so we slept in a cold bedroom the first night and found the way to set it for the next night. It was merely me not setting the auto fan. 😐

akot,

Are you talking about the furnace or the heat pump?

You may not have a heat pump on your bedroom unit.

RV Heat pump? That's new to me.

All gas fired heaters/ furnace has an outside air intake and exhaust. So if you think you have two furnaces, there must be two outside air in and out places.
