We are having the same problem ~ we just had an anti-gust hood installed thinking this would be the solution but we were wrong - total waste of money it is now louder than ever! I made a recording of the banging and emailed it to the company, I am still waiting for a response.

Hi there leeanne if you can get to the vent some have tabs to hold ot closed on windy days . I keep mine closed up all winter due to nighbour piles snow right under where it is . I too was driven half mad by the constant flapping during windy days and right near my livingroom area . Have you checked for tabs to hold it down?

We just spent a small fortune on our kitchen where we added an outside exhaust fan. Now I'm having the same issue of the vent flapping. It's ridiculously loud. I'm looking into options as well to fix it. I'm glad to hear others have the same problem

I just moved into a new home with this problem, crazy loud noise coming from vent hood in high gusty winds. Has anyone come up with a solid solution?

Same issue on my remodel

The range vent on our new house was driving me crazy on windy nights. The vent cover looks pretty similar to the "gust proof" models. In a desperate effort to quiet it tonight I wrapped duct tape over the end of the flap which has helped. It weights it just enough to reduce the flapping and quiet when the wind really gusts and lifts it. I might try adding a few coins to increase the weight.

Kerry, can you post a picture, please? The noise drives me crazy too! I'm assuming that's on the outside? Thanks

This was a quick fix the other night. It would probably be better to use a thin foam weatherstrip tape.

After countless times of waking up from the flapping of metal, I stopped the noise by putting a spatula to keep the flaps open. I hear no noise and I will be going back to sleep peacefully. I didn't realize it was wind until after I read these comments. And tonight is definitely very windy.

We have this same issue with a new home at the beach. (It's windy at the beach! Who'da thunk?!) We complained to the builder, and his "solution" was to wedge a piece of cardboard beside the flap, between it and the vent cover, so that it's stuck in place, partway open. I don't really think that's a good solution - now we have a permanently-open vent, but at least it did stop the noise. So y'all could try that. I'm gonna try some of the other solutions presented here, and will let you know what happens. (First I'm going to have to buy a ladder! :-) )

I have since added some foam weather stripping and the problem is completely solved.

Thanks!!!

I just taped it shut. It was driving me crazy! A temporary solution yes, but at least it's quiet now. Lol

I put a felt sticky circle (technical term) for the feet of furniture on wood floors on the flap. It added weight and silences the flapping.

Kerry, did you remove the tape and coin weights?

Or was the foam weather stripping all that was needed?

I can imaginge grease could buildup on the weather stripping, but maybe some will help cushion :-)

My setup has 2 redundant noisy aluminum flaps.... one as you show on the roof vent, and another butterfly vent on the fan housing. I removed the outer roof flap easy enough, but the one just beyond the fan motor is now the issue, as not sure how to access the top side of it to add weights.... or maybe should remove it and go back to just the one on the roof cap(?) Certainly don’t need two.

I left the coins and weather stripping. It has worked perfectly and we have not had any problems with normal operation of the vent.

I had this problem and found comfort in knowing that others had it as well. But I didn't like the solutions as most involved changing the exhaust vent and I just got it all installed a few months ago and didn't want to rip back into the well. Someone recommended taping coins to weigh the flap down and it got me thinking...

I took a small high-powered magnet the size of a watch battery (lots for sale on Amazon) and placed it just inside the duct so that magnetized the entire hole that was in contact with the flap. Problem solved! The magnet is strong enough to keep the flap in place during breezes and heavy winds but the flap opens when the exhaust fan is turned on. Cost of fix is under $1. :)

Bryan Cooke, can you share a picture please?

Same problem. My solution was to split open a foam Nerf gun dart and put that over the bottom edge he of the flap. Used duct tape to hold in place. Worked like a charm.

Will these suggestions work for a bathroom vent fan? Mine rattles ALL NIGHT

would the weather strip or nerf foam options hold the vent open in a way that you’re either losing air like heat or ac to the outside or making a space for bugs/critters to get in?

Taping shut may stop the noise but then defeats the purpose of the vent .

I’m about to go through a bathroom remodel and am going to ask for a new fan ...anything I should ask for specifically in the model I pick or the way the bath is vented to avoid this after the reno?

Don‘t tape it shut. Just use the tape or weather strip to give a little cushion to the edge of the flap so that the metal doesn’t bang directly against the metal Surrounding the outlet hole. The magnet idea that someone else had is a great idea to keep the flap from bouncing.

Thank you for the magnet idea. It worked really good! The felt pad didn’t work. The vibration from the damper slamming into the pad still created the rattling sound even with the cushioing from the felt pad.

Hi, I would like to post a simple solution to my particular vent hook design.

The magnet helps to keep the vent shut when not in use, but releases when the fan is on. The flap is made of aluminum so a paper clip is needed for the magnet to be attached to. The housing of the flap is galvanized steel, so you want to also make sure that the magnet won't be stuck to the back side, keeping the flap in open position.

Hope it can help someone :)

Any chance you can link the model or power on that magnet?

I was racking my noggin solving this problem and after reading this thread I figured I'd get on with fixing it. Figured I'd post my solution hoping it'll stimulate ideas like others here did for me.

I first added a little weight to my door by drilling a small hole and inserting a nut and bolt. Worked for light winds but we live in a trough surrounded by farm fields and it get to blowing pretty much all the time.

I knew I needed a magnet/catch setup so started searching my shop for items.

First, found an old cabinet magnet catch and dissected it for the magnet.

Now for the "tab". Needed to be steel but flexible enough to manipulate and bend. How about an old dryer vent clamp?

Cut the metal to size and drill hole to connect to the vent door.

Continuing after accidentally hitting POST...

Attached metal tab to door via same nut and bolt.

Attached magnet to door. My vent was steel so it stuck nicely but I augmented with a little piece of 3m tape.

A little tab bending with a pliers so the tab hit the magnet flat.

Tighten it all up good.

Modify critter screen a bit.

A viola! Works like a charm. My vent hood produces more than enough flow on all setting to open it and it snaps closed with a nice audible clunk.

The End.

Are you all fixing this problem from the inside of your home or exterior?? A year of this nonsense and I’m DONE!!!

This is exterior

Exterior.

Exterior. The solution I posted attaches a magnet/catch to a single range hood vent flap or door. Looks like you have a basic plastic dryer vent with three thin and light flaps. Even the slightest wind would move these. I'd think about replacing what you have with a more robust and heavy vent that has a magnetic catch on a single door with a hood that blocks at least some wind. Good luck.

Turn the fan on low to open the vents (keep from banging) on a windy day or time when annoying you till you can fix the issue. This way your not out at dark killing your self.

Had the same issue on a 2nd dooor vent in high wind area. Added a couple magenta and strips and now it holds in place when not in use and the Air flow is plenty to open it up when pushed.

This fixed our issue.

My problem with the vents (kitchen, bathroom, laundry room) is that I can hear road noises (mostly large diesel trucks and harleys) from outside through the vents. Any solution for this?

We have a sorta similiar issue. When it is real windy the wind-dust-sand comes down the roof vent hood and the dust and sand settle all over the rangetop and counters. Also my house is really dusty and I think this is one of the reasons. It gets loud on real windy days but the noise doesnt bother me, it is the mess of dust and sand. Is there anything that I can do to prevent this? My husband and I both suffer allergies and this has been a real trial. We already spent a small fortune on duct cleaning, top to bottom spring cleaning, carpet cleaning. Bought 2 expensive air purifiers and a new hepa vaccume. Please any ideas or help would be appreciated.

@Jonathan cook what vent is this? Do you have a model number?

I had a similar problem woth a new direct wsll vent hoop with fla. it would open and close in a mild to strong wind. it was bery annoying. i believe i solved the problem using refrodgerator magnets.

the issue i had was the flap was aliminum so the magnets attached to the vent wall would not work with additional help. i resolved the aluminum flap by using teo sided tape to attach steel washers to the flap and magnets to the vent side. that seemed to do the trick for now but not sure how long this fix will last.

see attached picture.

Read what Bryan Cooke did 3 years ago with a magnet and decided to try that $9 on amazon and i had some small magnets luckily they came with double sided sticky pads with them so i could stick them to the inside since my vent is aluminin they won’t magnetize to the aluminum metal i put one on the flap and one inside the vent (you can also use masking tape to attach them to the metal) and it works perfectly!! the flap immediately shut all the way down and stayed even though it is super windy today i went inside and turned on the vent and it opened up just fine!! great solution!!

One day, someone will "invent" one that works. This is just the tip of the iceberg, from trying to attach the metal ducts so they don't stop the microwave damper moving, to stopping wind and noise, and if you live near the breach, humidity and mold..,.

Our kitchen vents up in the ceiling about 10 feet horizontally to the living room fireplace chimney, and it‘s flapping INSIDE the chimney. There isn’t access from the attic either. Any tips?
