This Jenn-Air® luxury electric radiant downdraft cooktop offers a sleek cooking surface with four radiant elements, which offer responsive performance. It also features the impressive JX3™ downdraft ventilation system, which quickly and efficiently clears the air without a hood.

10"/6" Dual-Choice(TM) Element

An electric element that features two element sizes at one position and has a maximum heat output of up to 3,000 watts for greater cooking flexibility.

DuraFinish(R) Glass Protection

DuraFinish(R) Glass Protection helps keep your ceramic glass cooktop's surface looking like new by resisting scratching.

Perimetric Extraction

Provides exceptional ventiliation performance built into an attractive design by capturing cooking vapors through a thin slot and speeding the air, all while maintaining quiet operation.

Color-Coordinating Die-Cast Metal Knobs

Robust, die-cast metal knobs offer precise control and color-coordinate with either the Euro-Style Stainless or Black design of these cooktops.

Oblivion Glass Design

Sleek black glass that seizes its surroundings. Lose yourself in the depths of infinite possibilities that dare you to explore your limits.

Semi-Flush Installation

Subtlety that dares to be ignored. Standing semi-flush at 3mm above the countertop, this precision edge is minimalism magnified.

problems with ceramic finish.

by: Crystal8

No, I would not recommend this to a friend.

I had a Jennair ceramic cook top for 13 yrs. I replaced it with this product. The finish on the new one mars and stains with any spills, even water. I use the same pans and cook the same way as before. I didn’t have this problem. A teapot was filled too full and boiled over. There is now a stain that won’t be removed. I started with ceramic cleaner. I tried every suggestion I found. Now I also have scratches. Please see the attached photo. I’m so sad. I’ve had several Jennair appliances and have loved them. This one is a failure.

Missing a great feature........

I had this cooktop for 6 months. It responds well. I wish Jenn Air still made the modular cartridge with grill insert, just like my prior one which is 26 yrs old. Please bring it back.

They don't make them like they used to......

Had to replace my old one after dropping something on it and it cracked. This was after having it at least 15 years or more.. Cooked on the new one with a glass pan and it got scratches on it? had it 4 days...I cant get the discolor off with anything, so I bought a portable electric 2 burner cooktop for $75 and use that. At least the new top will look pretty good when we sell the house...What a waste of $2300...

Horrible redesign

My second generation of the same cooktop. I can’t believe how poor the design is : knife sharp corners, control bases that don’t come off for easy cleaning. The edges have chipped twice for no reason... nothing hard hit them. Only one light to indicate a burner is hot, the old model had a light for each burner. I could not be more dissatisfied.
