Downdraft Gas Cooktop

by: RobertBG

Yes, I would recommend this to a friend.


Love the gas cooktop and downdraft exhaust fan feature One of the electronic igniter switches under the knob failed within 2 months but was replaced under warranty

It's a great appliance but has a few nuances

by: InformedBuyer

Yes, I would recommend this to a friend.


We did a LOT of homework before buying this model We love this cooktop Replaced a old GE cooktop Compared to the KitchenAid model this one has a much better quality steel scratch resistant the knobs are also made of steel vs plastic which looks like steel on the KitchenAid and brass burners vs alumunium on the Kitchen Aid I like the automatic flame reigniter also but it see below The grates and burner tops were discolored during the first week but customer care sent me a replacement set note that cosmetic issues are only covered for the first 30 days The replacement has been okay so far The fan is VERY powerful and effective even at low The fan is more silent than my old GE but its still loud This has a few nuances you need to be aware of 1 When using the flame at low AND the fan is on the flame starts flicking and the this kicks on the automatic flame reigniter which things the flame is out So you need to increase a flame past minimum when using the fan 2 The flame on the FAR end of the burner opposite end to the fan grate burns brighter and the flame near the fan intake side of the burner burns lower The designers apparently have accounted for the fan being on all the time in their design of the burners so when the fan is on it far end is sucked in and theres an even flame all around the pan However when the fan is OFF the far end of the flame on the burner is almost 2 times higher than the burner end closer to the fan So this causes the pan to heat unevenly infact with the largest burners it even goes all the way around the pan and can burn your hands if you arent careful Note this only seems to impact the cooking at high flame at lower flames it tends to be equal on all sides This design issue is why Ive given it 4 stars while I appreciate the thought into keeping the flame even with the fan on it makes cooking on high flame impossible with the fan off due to uneven heating But our GE cooktop never has this to with the fan on it was impossible to cook evenly Its how you look at it We still prefer this since with the fan on you can use it as high flame with the fan off you typically dont ever need high flame since the burners are so BIG so it works out fine But something to be aware of depending on your cooking style Otherwise we love our new cooktop and its easy to clean

Jenair Stove

Yes, I would recommend this to a friend.


Great except cannot get a very low fire to simmer Great for high and medium heat

JX3 - just alright....

by: erwin.lutz


I therefore am surprised for heightened Jennair interest to offer me extended warranties on a new unit Should I be concerned Unit works as specified no extra value for money and I have two serious concerns 1 the units gastop signage for each dial looks fragile too light to read and appears to be faded 2 performance I will only review a product after 6 12 months then 1 and 3 year

Cooks Wonderful with Minor Issues

by: New Kitchen in KC


Cooks wonderful and fit our unique kitchen island perfectly But two disappointments in light of the cost the exhaust alters the flame significantly which can result in uneven cooking and the beautiful stainless surface scratches remarkably easily
