Normal furnace operation ?

[ky bob]

We have used our furnace 2 or three times so far this year on our new to us 2015 33.3



This past weekend, we turned the furnace on and the furnace heated the coach, but the front air conditioner fan came on also. Is this normal ?



It was a bit noisy and I wasn't sure if the front ac unit overhead fan was supposed to come on with the furnace.


It was too noisy for us , so we turned the furnace off and plugged in our two quartz heaters and enjoyed warmth and quiet.


Our old gas coach had a furnace that worked completely on its own. The only fan we heard was the furnace fan.

Change the Dometic thermometer from hi/low to Auto and it will turn off. Remember to change settings as you no longer need furnace.

YEP^^^^^


FAN setting on thermostat is for the A/C Unit fan
If NOT in Auto it will run when furnace runs....idea is to 'circulate' warm rising air to even out the interior warmth.


Idea---theory except it just blows cool air

yep, answers are already here. I run my furnace on "auto" so AC won't go on.
