Malvin, heater issue

[Malvin]

We have a new 2021 Miramar 35.2. The bedroom heat supply blows like a hurricane right into the door bouncing back into the bedroom. It is like a sauna and the rest of the coach is cold. Anyone else have this issue? What's the fix?

I don't have a miramar, but our hurricane had a similar issue. I pulled the intake grill and noticed that two of our trunks were not even connected, and the ones that were had holes in them. After fixing all of that only the cab is chilly now. As for the bedroom, we installed a closable vent that helped a bunch.

Thank you for the help. We are bringing in the coach to service dept. in couple days. We'll see what they come up with!

Good luck, and welcome to the forum!

On my 2020 Miramar, when you remove the return air grille right under the refrigerator you see the heater behind and the air ducts that go into the floor right in front of it. These under floor ducts typically go toward the back and one toward the front in the floor. In mine, they had not properly installed the duct fitting on both of them and I had to remove and re-install.
And vacuum the sawdust out of it. And then vacuum it again. Still pushes out sawdust, so much for the factory cleaning anything. Lots of posts on that subject.
After I reconfigured the flex ducts to eliminate a twist and took a bit of time to secure and seal everything they work much better.
