American Coach: Furnace Connection to Heating Ducts-98 Eagle

[FormerBoater]

My #1 furnace blower and burner are working very well, but I am not getting any flow through the heating vents in the coach.


I know, it is not winter but we just did a trip to New Hampshire and ran the heat a bit during the journey (drove thru a snowstorm in western Mass on May 12th!)


My theory is that the duct has dislodged from the furnace due to some of the rough roads we encountered on the trip.


Does anyone have a clue as to how to easily take a look to see if this is in fact the case?


I have opened up the panel where the furnaces are located many years ago, but I cannot remember if you can actually see the duct to furnace connection from there.


Any and all input is appreciated as always!

Mine may be different from yours since mine is a 97, but mine has a panel which can be hinged up for access after removing a couple of screws from the bottom. Good luck!

boater, I've had them out. You should see a few screws under the outside door, under the furnace exhaust vents. You'll have to just about lay down to see them.
Mine has 2 screws. Once screws removed the door hinges up and the furnaces are both easily accessible. The duct hose entering coach can mostly be accessed there as well.
Mine had a rats nest in one. I removed furnace and used a electric leaf blower to "back flush" the ducts.
I also managed to snake a air hose in ducts and blow them out.

My $.02 is to open the compartment, visual inspection of duct hoses and turn furnaces on... problem should show up...

Thanks Mack, it will be interesting to see how "mostly accessable" the duct will be.


If I have to remove the furnace to access the duct hopefully it will be self-evident how to get the furnace out of there!


I seriously appreciate your help on these issues. You are a valued member of the vintage American Coach tribe!

Ha-ha, I just reread my post..I got tickled at my "mostly accessable" comment as well, lol..

But you can see where the duct hoses attach to furnace.

My value here is gaining every time I do something to my Eagle, I got it hands on! Ha-ha
Peace and happy travels!

It's easy to get the furnace out once you raise the exterior door. The furnaces are side by side and it will be obvious how to remove them. Then you will have direct access to the ducting.


Hope that helps!
