AC Blowing Cold in main room, front room no flow

[Msu50000]

Our AC has been blowing cold and working as expected throughout the season. Sometime during the night the vents in the bathroom and master bedroom stopped blowing any air at all. I can't feel anything even with just the fan on.

The unit we have doesn't allow me to turn off certain rooms, There are circular vents in the ceiling and the main unit has the slider to cover the vents on it's side. Any ideas? This is a new trailer this year.

You do not want to cover any registers. The A/C system requires a certain amount of air going thru it to function properly and most RV duct systems tend to be under sized to begin with. Blocking registers will lead to the A/C unit freezing up.

Did this and there is a foam insulation piece that must have came loose or slid over and covered the vent line going forward. It fits in very tight so not sure how it happened. Took the covers/vents off the bottom of the AC unit (inside TT) and was able to get it back into position and secured. All good now. I'll be covering the 4 vents in the main room this weekend.

Thanks for the help guys.

I've seen the ducts almost crushed flat with insulation on top of them. Might check with a mirror to make sure they're still free flowing.

We had same problem. We blocked some of the vents in main living area and bathroom to force more air into ends of trailer. We now have even air flow in all parts of trailer. We used plastic clear lids with small hole cut in center then taped them to inside vent covers. Can't see them at all.

I'll dig into them this morning. Are there replacement circular vents so I could selectively close certain ones? Thought about taping/blocking some. There's 4 in the main room that seem to be completely overkill with the main unit right next to them...

Insulation or some trash may have come loose in the duct. The little round covers will pop off and you will have access.
