Roof Vent Opening by Itself?

So I just replace a cracked vent. No it opens by itself. I close it, take off and a few miles down the road, it's open approximately 45 degrees. Anybody have this issue? How did you fix it? I'm think the air flow is causing some type of vibration that's causing the vent to open itself. I'm thinking of tie tie wrapping it or alternatively installing a magic vent but really don't want to do that.

Yea that seems more logical. I was watching a youtube video of a guy that had the same problem and put a cover over it to prevent it. He though he had a ghost, ha. I might have one also. I tightened it up pretty tight to day, we'll see.

The vent in our Coachmen Leprechaun 230CB is opening by itself. Three separate times I have found it fully opened. In every case it was windy and we were traveling on I90 in Montana between 60-65mph. Anyone have a fix?

Maybe a Velcro strap to the plastic frame? Something to stop the crank from turning.

I'm guessing the vent is acting like an airfoil by creating lift and as long as the crank handle is allowed to turn, the vent will open.

Had one in a conversion van once upon a long time ago that did that.
Took a small wire hook and fastened under one of the screen screws and then used a rubber band from the hook to the crank to keep it from opening.

We had that happen once on one of ours while driving, making sure it was really tightly cranked solved it. Then a few months later we put one of those vent covers over it and haven't seen a problem since

Yes the first time it happened I thought well I just forgot it open but it's happening often now I think I have a ghost in the trailer.

Putting a cover over it seems to be the best and easiest solution. Then it doesn't matter if it's open or closed.

yes thanks, that's probably what's going to happen eventually.

What kind of cover are you talking about? I am not familiar with what you are talking about...

If it is not closed tightly the vibration will allow it to open especially if there is another window or vent that allows air to enter RV while moving.

It's a Camco replacement crank vent. Typical vent like nearly every RV has.

Thanks, I cranked it tighter and it stayed closed for the last short trip to the scales. I'm heading out fo a couple hundred miles this weekend, I'll see what it does. It cranks so easily, It's, as you said, vibrating and the pressure differential is allowing it to lift open on it's own. I didn't have any windows open however.

Something similair to this:



It allows the vent lid to be open without letting rain in.

I installed a "hook" using a light weight hanger that has the command strip which I can remove anytime. I stuck it to the plastic frame after tightening the cover down...and installed it in such a way that when I put a pony tail band on it and hooked it over the crank it would no longer rotate....I tested it on Hwy 90 with a lot of wind yesterday and after driving 500 miles the vent did not come open one time as long as this was hooked up. Once at a rest stop I took the band off and cranked it a little and sure enough, the vent started to move up and down with the wind, just a little but eventually it would open all the way. So thanks to a little hook I purchased at WalMart and my granddaughters pony tail band, the problem is solved. Problem solved.

Just put a Maxx-Air cover over it, money well spent.

We just had the same thing go wrong. The first time we took it out and being new to this trailer we assumed we missed a valuable step. We returned home yesterday and the same thing happened. In addition to the emergency window was popped open. We know for a fact we did not leave that open and had it in the correct locked position on our 2104s. Thanks for sharing
