We have new house and have cold air coming from Jenn-air vent. What can be done to stop this? We had a Jenn-air in our previous home and did not have this trouble

where there is a will there is a way --correct you will break it - it is tacked to frame ---to remove it you need to tear apart the unit ---purchase a claw style part retrieval tool $4 at harbor freight -$11 home depot---lowes etc

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.

I put a tea towel over the vent surface, also a piece of bubble wrap does the trick if used as insulation, and both can be removed quickly to use the surface.

Sorry to read about your problem, I hope this helps you out.

you can purchase a inline boost fan, try a Granger in your area

I tried to help you. Please help me and Rate/Vote on my response, thanks and good luck

You will have to look underneath the unit if it is installed in your kitchen counter for the model and serial numbers.

The poupose of either is to eliminate any smoke created by the range or grille and move as much of the cooking odors to the outside. I wouldn't use both at the same time, but if the hood is vented to the outside, it would be just fine to use only the hood. Aregular cleaning will be necesssary. The downdraft has limits as to the distance it will efficiently exhaust air. Flex hose should not be used. And excessive bends or vent length, cuts into the efficiency.

Sounds like the fan is bad. It can be replaced without replacing vent.

Someone suggested the flapper needs replacing.
Thanks for your help.

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

How do you get the inside area of the vent clean from the grease and oils where the filter is?? I have a rectangular box style downdraft that the vent goes into the floor, I pulled the filter, but the box is to slender to get an arm into to scrub the grease....... does the bottom come off, or is it a sealed unit? How do you get all the brease from the bottom if you cannot reach it?
