Roof Fans On With Furnace - Montana Owners Club

KemoLondon · 04-18-2019, 05:03 AM

I have a two A/C rig. Front and Rear. When we were on the road we had to use the furnace to take the chill off and it seems the A/C fans are on when the furnace is on. Is this normal? They are working even when the furnace turns off. Any input appreciated.

On the thermostat (or both if you have 2) set the FAN to AUTO.

Yep! Had to look in the thermostat IB again myself a couple weeks ago.

Click to Fan, click to on Auto (Au) first then click to the heat setting. It is NOT intuitive

Also, make sure most of your furnace vents are open when your slides are in. We could run the furnace on the old Monty, but not on this new one.
