Sticky external stove vent

[Ron in BC]

Thanks, I'm now wondering if I'm the only one that has a range hood without a plastic cover plate, maybe mine fell out during installation.

Other thing I noticed is that the bottom edge of the flap appears to very slightly rub on the bottom of the housing. I might give mine a little sanding.

At any rate we'll keep using a clothes pin to hold it open, both for max. air flow and to serve as a reminder to lock the flap. Good thing I found it because it's provided a direct path in for mosquitoes.

Better there than inside the trailer.

So, we have one range hood with the recirculating vent wide open, one with a plastic plug and one taped over with silver tape.

For anyone who wants their fan working as best it can, it'd probably be an item worth checking.

You are right about that Ron . Glad you pointed it out though so I could check . Thanks for the head 's up . Still need to check under bed and make sure my 120 is still secure . I might add a cable clamp to help it stay that way . Just pretty busy with other things right now , but I will get to it . Pat

cpaharley has the right idea, let the powerful MaxxFan do the work!

Glenn, did you try operating the fan with the mesh screen removed?

On mine with the mesh screen removed the flap opens fully when the fan is on, with the mesh screen installed the flap does not open. It is the charcoal filter inside the mesh screen causing the restriction on mine. The mesh screen without the charcoal filter you can see through the screen, with the filter you cannot see through. And yes mine has the recirculation opening blocked with the plug.

Does anyone have a picture of plastic plug that some of us are missing ?Pat

[Ron in BC]

OK, so that's one open, one taped over with silver tape and two with plastic plugs.

Yes Ian, I tried it with the screen removed and the flap didn't budge. When the fan was running I blew at the fan and that gave it enough pressure to open the flap. The flap is clean and free of any possibility of friction which would cause it to stick. I think the style and pitch of the fan blades are of a design that inhibits air movement. (Lousy design). When the fan is running without the screen there is more air movement being thrown sideways from the blade than there is air being directed towards the exit vent. This isn't a very big deal for us, but if we'd known about it, we would have omitted having the range hood and had another led light fixture fitted in its place.

Is it time to gather the forum engineers ,paper , pens and fix these vents? Pat

I don't think the problem is the vents, but the fans. If you look at the blades their not really a high cfm design, and much of the air they pull escapes from the housing and not out the vent. A fan with better blade design would push more cfm of air, and the vent would be forced open more easily.

Has anyone tried changing the pitch of the fan blades, they can easily be altered? Or replace the noisy fan with a little computer fan, but first verify it will open the flap.

Ian G has it right. 2 points.
"If you remove that mesh screen the vent works great, lots of flow, the charcoal filter is just too restrictive for that type and size of fan."
Jeesh, follow the KISS principle it is so easy and ineffective to speculate.
Take an awl or ice pick and poke holes (aprox. 1/8" diameter) through the charcoal matrix and between the openings in the metal wire mesh grid to greatly increase the air flow through the filter. I did this several years ago to increase the flow of air drawn through the filter and the damper flap opens 3/4 of maximum travel. No clothes pins or clamps necessary !

Sounds like a redesign COMMITTEE is being organized. Just remember, a camel is a horse designed by a committee.

Not in my case, I removed the screen and got exactly 'zero flow', the fan makes noise and spins like crazy, it just doesn't have enough poop because of poor blade design to create enough flow to open the flap.

I like looking at the fan change out option. I'll be over at the trailer today and will see where ours is at on performance with and without the screen. Haven't even turned it on to date yet.

Good and check to see which category you're in with the interior re circulation vent.

Not the best configuration for the fan. It blows vertically at the nearby "roof" of the housing. I was thinking a more efficient setup would be two small computer type fans, side by side, mounted just inside the vent flap and blowing straight out.

How's that for fixing something that's only half broke.

I solved the problem long ago ( not that I knew I had one ). I cook outside.
I turn on the Maxxfan when boiling water for coffee ( keeps smoke alarm from going off ).
I'm more concerned about losing the pins that hold the flap closed.
