Poor Dometic A/C on 2019 Jayco Jayfeather X23E

Hi all,

A few weeks back, we took delivery of a brand new 2019 Jayco Jayfeather X23E. Our first camping trip was on a hot weekend, and the A/C (Dometic Brisk II) struggled to cool the interior. But it wasn't running flat-out. Even with the temp set to full-cold and the fan set to 3, it would alternate between A/C and fan-only every few minutes.

So I popped the filter cover and noticed that there was lots of cold air leaking into the intake side, blowing right onto a copper thingy (temperature sensor?) that is hanging down:



The unit stays in A/C mode for as long as I put my hand around this copper thingy.

The air leaks appear to be shunting around the cold/intake divider along where Jayco boxed in the roof opening with a Luan-like material:




(The paper towel in the second picture was an attempt to plug one of the gaps where cold air was blowing in.)

Should I just take this back to the dealer and ask them to properly isolate the cold side from the intake side? I've read about coil freeze sensors and stuff too - I guess they'll check all that out?

Thanks in advance!
  • Do it yourself. A quick fix and not worth the hassle with the dealer. Plus, you'll know it's done right

    I feel like at the very least, the plastic part below the roofline (air distribution box?) should be dropped to get proper access to all that stuff. It looks like some wood screws around the perimeter and two bolts behind the intake cover. Is this reasonably straightforward for a DIYer?
