  1. Xragod

    I can’t wait to use the Cooktop. The one they delivered has bent knobs. I’m awaiting the new one.

  2. boapcubby

    Works well, no smell with all cooking fumes being pulled downward out of the house. Nice quality.

  3. John

    We love our new JennAire cooktop and the whole experience of buying from BestBuy! Cooktop price was as good as any on the net. Was installing the cooktop as a replacement for an old Jenn Aire cooktop. Best buy offered a free pre-measurement so I did not have to worry about it fitting into our granite countertop. Installation was timely and problem free. A great overall experience.

  4. Kitchenaddict

    Very impressed with my new Jenn Air downdraft cooktop. I was forced to replace old Jenn Air as I already had a Jenn Air downdraft cooktop. Thus one is much more attractive and professional appearing. Works great. Would buy again. Also very impressed with Best Buy service

  5. AAQ747

    I did not have a lot of choice in the market due to the design of my island. I went with this product specifically because of the brass burners this product was offering. In home consultation was a breeze and the product was delivered and installed in a timely manner.
    Some users mentioned that the built in exhaust would pull away the flames from heating well thats true thats why i give it 4 stars. I would still recommend this product to anyone who have the exhaust duct installed in the cabinet below.

  6. StuK

    The look of this in a kitchen is awesome. Ease of use is an added bonus.

  7. Rana

    The unit functions well. The only possible future improvement could be darker letters/symbols next to the knobs as the signs are not clearly visible.

  8. JennAir

    Love this cooktop! Easy to use, consistent cooking.

  9. TexasTech

    Love this cooktop have had 3 other brands and not happy.

  10. HappyCustomer

    We love our new cooktop, and purchasing from Best Buy was easy. We had a very knowledgeable salesman, and then picked it up at the store.

  11. Anderson

    This stove top may have been more expensive than some others. But after having installed and using, it was worth the cost. The middle vent works great to pull heat & smell down and out of kitchen. It has several speeds to vent too.

  12. DISAPPOINTED

    The downdraft pulls away half of the heat. You have to cook without the downdraft on.

  13. Campy

    This item arrived twice with illegible writing on the stovetop. You could not tell which knob controlled which burner without extreme visual effort. Not a Best Buy issue but a Jenn Air quality control issue. Really wanted the cooktop but could not accept the poor manufacturing.

  14. Bakefamily

    Great product, works well just as mentioned. We really like it.

  15. SOUTHERNCuisinerocks

    Stove works great so far. Have only had it 2 weeks. Had the electric Jenn Air for 30 years. Hope this one lasts as long. Only downside is the downdraft fan is loud, but does have 3 speeds. My electric Jenn Air had a loud downdraft fan also, but only one speed. Think this is going to be a joy to use for many years.

  16. SSPKitchen

    The different sized burners are great. The details by the knobs is very faint

  17. EDfromIN

    Very happy with it. Replaced an old 30″ JennAir electric cooktop. Fit perfectly into existing space on counter although the fan was slightly larger than the older one so we lost a little storage space underneath. Cooks well and the fan provides good airflow without being too loud. Only minor complaint is that the images next to the knobs indicating which burner it controls are a little hard to see but we will get used to it so not a huge deal.

  18. Kamran

    We had to replace the sheet metal screws with flat heads in order to fit it into the countertop cutout. The cutout was exactly the dimensions listed in the manual.
    Another option (for anyone else) is to increase the cutout by 1/16” to get passed the screw heads.

    Also, manual calls for foam seal to be installed around the rim (between cooktop and countertop). But it didn’t come with the seal. I did call them and they did send them; except it was quite short and I had to call them again and ask to send three more packages.

    Otherwise I would have given this five star.

  19. Will

    Wonderful product. We owned a JennAir downdraft cooktop before.

  20. littlesand

    We were replacing an older gas cooktop. Due to the 30 inch size and needing a downdraft model, we were limited in choices. This was the most expensive, but is working like a champ. Very satisfied!

  21. IncompleteInstall

    The cooktop came without burner tops and now kitchen is not usable for days. They can’t even tell when the burner top are going to be shipped.

  22. Mario

    Great cooktop. Quiet, efficient, and quick to warm anything up. The construction is very solid and the brushed metal looks great. In our kitchen, it replaced a 20-year-old GE that had only 2 burners left working. The JX3 fit in perfectly. It’s not cheap, but absolutely worth the investment.

  23. bigDVB

    It’s ‘ok.’ We had to settle for this unit. The craftsmanship is not quite what we had expectations of. The surface unit indicator markings are inadequate and not easily visible. The knobs don’t operate as smoothly as they could. We won’t even get into the install, which was a BestBuy Nightmare!

  24. sauce94

    Moved into a new home and upgraded the old cooktop for this JennAir model. It is really nice with Brass Burners and looks really good. This model comes with a built in ventilation system as there was no hood installed. I had reservations about it’s ability to handle smoke but it works really well.

  25. Unknown

    The installers (Nick and JRock) were very good, they measured twice before installing and did a professional job!

  26. Runningmachine

    Reliable gas burner and installation was excellent. Recommend.

  27. biff8989

    Love this stove. Functions great with 4 different burner sizes for any job.

  28. Puneet

    The cook top is good, the only reason I knocked off two stars is due to the downdraft. It is so powerful that it starts sucking the flame and the temperature spread is not even.

  29. MS20191

    Product (stainless steel) what we saw at the store and online in the pictures is not what was delivered. Lettering is barely visible on the stainless steel model. The granite counters around get very hot after cooking. We thought it was a defect with the unit regarding faint lettering and ordered the same as replacement. But when the replacement came in, we had the person open the box before installation and found the lettering is also faint at which point the installation person (on the 2nd vist) mentioned that he has installed a bunch of these and the lettering is faint in the stainless steel models. With the installation person who installed it first had mentioned it so we could order a black model. As counter tops were getting very hot, when i ordered the replacement, i mentioned about the heat transferring to counters and bestbuy told me they will instruct the installation person to install a tape/foam seal between the cooktop and the granite counters to reduce heat transfer but installation person said that they recieved no such instructions from bestbuy. If they hadn’t hauled away our old GE Profile downdraft cooktop, we would have just cancelled it. JennAir products aren’t what they claim and bestbuy experience hasn’t been good so far. On the exhaust fan, even at the lowest level, it pulls the flame away and causes uneven cooking. Attaching a couple of pics on the lettering. Knobs were bent (which the installation person tried to straighten) and I was told it is a manufacturing defect. We were told by sales person that JennAir is better than KitchenAid (same exact model) but at a bit higher price but we don’t agree with what we have seen so far.

  30. RickW

    This cooktop turned out to be everything I expected it to be. The downdraft is very powerful and quiet and the burners are immensely adjustable. Best purchase I’ve made in quite a while.

  31. Hose

    Jen air is the best for this type of cooktop. Must have

  32. Poonam

    Nice looking, functional gas stove with sturdy grates and knobs.

  33. Ring

    We bought this product looking past all the other products which were cheaper and thought this is a high brand and would stay with us for some years . Kind of going by ” You get what you pay for”. We used the recommended stainless steel cleaner to clean the stove and it corroded the base . We called Jennair multiple times since it was under warranty they put the blame on us for using a wrong cleaner. And we used what they said , we feel cheated and definitely not worth the price . I would say you better think twice or stay away from this product . So disappointed and frustrated. The games they play with the customer.

  34. Faith

    Purchases and had this cooktop installed in November 2020 and in December 2023 electric ignition needs replacing. At this price point better quality is expected.

  35. JimG

    We studied different 30″ gas cooktops with downdrafts and of the limited ones available through different vendors, we decided to upgrade to this finer JennAir unit. We also purchased the installation service which turned out to be outside contractors, not Best Buy employees. After 3 months and looking into the slight smell under the cabinet, we just hired a retired gas company man to repair the small gas leak where the contract workers overtightened the new connection hose. After replacing the PSI regulator (original to the 16 year old house ), the connection hose and the valve for $375 we are SAFELY “cooking with gas”! We still love this premium unit … you should try these different BTU burners with different capabilities. It will change your COOKTOP life. This was a nice step up for a gas cooktop.

  36. Jason

    Great product. Working well. Installer didn’t have any issues.

  37. JeffreyN

    This thing lives to cook!! If we had to do the whole kitchen over we would not have done a downdraft cooktop. But this Is such an improvement over our original unit, all is well, in fact wonderful.

  38. Unknown

    Gas line not changed yet. Poor service and had to call multiple times to get downdraft installed. Gas line not yet changed and very concerned

  39. AshleyC

    The cooktop is working great! It was installed without any problems. The only reason I gave it 4 stores is the markings showing low to high are very faint and a little hard to see. Otherwise a great product.

  40. ZAGG

    This has been a good purchase and we are enjoying the new applicance. I recommend this product, it is good quality.

  41. ShitalS

    Jenn air 30 inch downdraft cook top’s brass burners discolored in 3 days like black carbon. I am not happy with the Jenn air product. Material is poor quality. When I called Jenn air they refused to send service people and they said our brass burners discolour. Very unprofessional answers. I would NOT recommend this to anyone. It’s waist of money and frustrating.

  42. Kiim

    Down draft is not strong enough to suck the air down

  43. JanC

    Work as expected, our house can only have this type of gas cooktop.

  44. VanessaW

    The knobs and grates are extremely beefy and solid, love the closed design of the burners and stainless steel which makes it easier to clean. A little disappointed that scratches appear where the grate rests on the stainless steel base; will need to lift up carefully . Overall love the stove!

  45. Rocklee11

    Awesome purchase!! Makes cooking so much easier. Would definitely recommend!
