We are noticing for the first time this year a cold-air draft coming through the downdraft grill on our Jenn air cooktop (the cooktop is several years old). We had deck work done this summer (the deck is adjacent to the kitchen where our downdraft vent may exit, although I'm not certain of that) and wonder if the exterior vent had a "flapper" cover on it that may have been removed. The deck is ground level, so impossible to see underneath. Any thoughts on how to eliminate the cold air draft?
I have cold air pouring in from the down vent. I checked the vent door on the outside of the house and it is closed. How can I reduce the cold air coming in? I have not been able to find a "cover" for the down vent that would be of a safe material. Right now, I'm just using a newspaper or towels! I have cold air pouring in from the down vent.

I just cover it with a kitchen towel when I'm not using it. If I don't, the kitchen is freezing in the morning. I just cover it with a kitchen towel when I'm not using it. If I don't, the kitchen is freezing in the morning.

The funny thing about mine is the microwave over the stove,it feels like a freezer.The flapper is on the outside of the house but the cold air still gets in.

I have called and contacted all that can think of, no such luck. I wrapped the frame with plastic wrap and placed it back into place to cut down the cold air. It helps..

I have the EXACT same issue. Older Jenn-Air cooktop w/ downdraft vent going outside. Cold air rushes in despite having the flapper in place. There has to be a better exterior vent or some way to prevent this. It's as bad as leaving a window open!! I've also wrapped my vent with plastic wrap which does do a lot to minimize it, but there must be a better solution...I have the EXACT same issue.

I stuffed towels where it was coming out then forgot and turned on the grill - not a good idea! Does anyone have an idea for a cover in the kitchen that looks nice?
The only way is to block off/check the flapper., if your not going to use for the winter you can disconnect the vent from under the cabinet temporaily and close off there till you can gain access to check outside grill

The downdraft is electric so there must be something malfunctioning with it. It is a high volume downdraft fan that is to be vented to the outside. Could it be that something has clogged the vent hole up, not allowing the fan to evacuate the smoke?
While I am not a big fan of Jenn-Air, their fans are usually high quality if they are installed correctly, with the proper vent lines.
You should just be able to set the cooktop in after you attach the downdraft, usually there are tabs on the downdraft that clamp on to the granite cutout. There is probably a closed-cell foam strip that runs under the lip of the cooktop, I would just make sure it seals to the granite properly (no gaps) and put a couple dabs of silicone in between the lip of the cooktop and the granite. Usually the cooktop is heavy enough that the silicone will keep it from moving around.
1) turn off power at the breaker.
2) remove hold down screws
3) pop up cooktop out of counter top
4) remove knobs and downdraft grille
5) remove ceramic top (screws around outside and also in side grille opening)
6) unplug burners replace with new burner
I can't imagine directing the downdraft vent back up to a traditional hood type system. Why bother, just don't use the downdraft or get a cooktop without a down draft and save money.
In granite, yes for any cooktop as long as someone can cut the correct size hole. Cooktops must be installed so the top is just about flush with the countertop. They all come with a template for cutting the right size hole in the countertop.
Thanks, unfortunately, we will be using for the winter. I'll have to try to get to the flapper under the deck. Ugh.
