Furnace blower

[89162]

Just purchased 2012 fun finder x model X210UDS...the fan on AC unit blows when the furnace is activated..heater has its own blower...is this functioning normal...????

Unless you have a heat pump the AC unit shouldn't operate from the wall t-stat. The wall stat would only control the furnace.

Thermostat has 3 settings...fan,cool and heat....with + / - and digital display for temp adjustment

Mmmmm. Certainly different than our, much older, system(s). Sounds like your AC system is perhaps ducted.
Ours is totally separate, both AC and furnace have separate controls. Air conditioner is 110V shore power and the furnace is propane/12v battery. Furnace is controlled via a wall t-stat and the AC controls are unit mounted.
Sorry, can't be much help. Maybe someone else can chime in.

Yes, this is the style thermostat that came in my camper and operates A/C and furnace.

I guess what I'm questioning why the fan is blowing through the ceiling duct when furnace has its own blower? Is this for better heat circulation?Is this how yours runs?

Do you have the style wall thermostat in the link provided?

In my 2012 XT276, the A/C blows thru the ceiling vents ... the furnace only thru the round vents in the walls near the floor.

The two systems are not interconnected vent wise. Maybe your A/C is low/out of freon so only blows warm air like any A/C system that is low or out of freon or the A/C temp is not set cold enough. ??

Same thermostat..heater isn't ducted...AC runs like fan setting...camper is only 21 ft...as soon as you fire up furnace the fan circulates air..thinking its designed that way as heat rises and AC recirculating air???...I guess my issue is when camping without electricity 2 blowers are running draining battery power

With the thermostat set on furnace, only the furnace fan should run.
With the thermostat set on A/C .... only the A/C should function.

Maybe someone messed with the systems before your acquired the unit. A good camper service center can check/correct it. I can offer no further information.

We have a 2012. I believe the thermostat is also used to set the fan speed. You will have hi/low/auto. When you set the thermostat to heat, in the auto mode the fan will not (should not) come on when the heat (furnace) kicks on. In the hi/low fan setting, the AC unit's fan will run continuously. I have a manual if you would like a copy.

I found the manual for thermostat..if set on high or low the AC fan runs for better circulation...on auto setting the AC blower will not come on...thanks

 

[89162]

Thanks everyone...issue resolved...operator error...lack of knowledge...lol

Well,I learned something too but then, I always have the thermostat set on auto so never had an issue with both fans running.

How do I get to the furnace to change duct and make connection at furnace[. 2012 FF 28 ft

I don't think you can...furnace blower just blows in common area...ducted blower on ac can just help circulate...
