Found the fix (my error).
The Fan setting was on Hi which means, when the furnace is on, the fan will run to help circulate the warm air from the furnace. This is a feature.
I turned the Fan setting to Auto, which means it will not run when I have it the furnace on.
I have a 2011 Fun Finder Xtra 275. I have the furnace on at 78 degrees and hot air is coming from the heat vents along the bottom of the trailer.
BUT, cool air is also coming out every A/C vent in the roof. I'm guessing it's about 71 degrees. Should the fan be running the same time the furnace is?
I have a Dometic Fan / A/C / Furnace control unit and it's set to Furnace when this happens. Thanks.
Great spot, family owned and operated. Riverfront spots are perfect for the dogs (and kids..and adults!). I have a 30' trailer....they have limited electrical hookups.
They have an onsite canoe rental outfit. Tubing too. Great place that I will go back to.
