Furnace Question

[aaronorange]

Is it normal to have this large furnace opening blowing under the curbside bed? We seem to be getting excessive hot air blowing out our kitchen drawers and under the bed. The rest of the flex duct looks fine. (The photo shows the large furnace opening directly behind the under bed access port.) Thanks!

That looks like the knockout panel on the furnace is missing .  You can seal it with silver furnace tape or find a sheet metal piece to put in place.

Please post the pix to oliver as a service ticket!

Thanks, that’s what I was thinking but didn’t see the knockout in plane site. I’m going to take a mirror to see if it slid under the floor. 😀 We are slowly making our way to Alaska from Arizona. Currently in Idaho and we are definitely using the heater. 🥶⛄️.

Difficult to tell from the existing picture but it's also possible the duct work has dropped out of the knockout panel. If you haven't already I would move your bed aside, open the hatch from above to make sure the duct has not vibrated loose and onto the floor.

routlaw, thanks for checking with us 😀We did look under the bed that’s how we found the opening and the rest of the duct looks secure. I’ll let everyone know what I find once we get parked for the night.

This must mean your ducting is detached from the furnace somewhere, or you have a large hole in the ducting. It's a pain when traveling, but you'll need to get under the curbside bed again to fully diagnose and correct. Most of these furnaces have forced air coming out fore and aft of the furnace. Check there first and then follow the ducting forward. If you can't see it quickly, run the furnace while you have the basement open and you should feel a lot of hot air blowing somewhere!

We'll be thinking of you, as you head north and it gets hotter and hotter in Arizona. Have a great trip! 😎

Have you done any mods to the duct work based upon "Snackchasers" post, if so i would look for a disconnect of ductwork from that port.

Your Oliver is #1238 what year s/b on your signature?  it would be interesting to see if the factory has changed the heater duct runs based upon Snackchasers changes...

it appears as though Oliver has changed the open heater ports, so this one appears to be facing the galley, as you can see it from the galley access port.

Back in 2020 (our model year) there was one open towards the rear, which must do a 180 to head towards the front of the trailer and one facing the front of the trailer. 
Our galley-side port still has its knock-out port intact.

For me it was like a "Fun House" optical illusion for a minute until realized what i was seeing based upon my 2020 experience....

Thanks to all that read and replied! Never found the missing knockout. Searched under the floor with my phone camera and inside the heat chamber. I went ahead and covered it with sheet metal and furnace metal tape, and all is back to normal. As stated earlier, all other ductwork is attached. To answer SNY SD UP, yes, I did modify the ducting to get better flow into the bathroom back a couple of years ago. Our ductwork is similar to yours, featuring one rear flex duct that turns 180° to head towards the front of the trailer, and another facing the front of the trailer. When you say galley side knockout, are you referring to the side facing forward to the galley/kitchen or to the center aisle, as in our case, having twin beds? Our missing knockout faces the center aisel. The photo was taken through the removable acsess port under curbside bed, Thanks again!

Yes,

Then you truly have a missing "knockout" as Craig astutely noticed, and again as he recommended you should let OTT service know by opening a ticket, and reporting such.

Be sure to add your OTT model year to your salutation as that helps all responding better understand what the issue may be.
