Those on eBay are radiant cartridges not induction. I am also looking for induction cartridges

Warning, don't buy Jenn-Air. Here is my review... When I first overpaid for this unit I tried to use the 'so called' bridge element that sales person told me would heat up across the two smaller elements into one larger element by connecting the two elements with a bridge. My understanding was that the centre part between the 2 smaller elements would also heat up to make for even grilling. but this is not the case. The elements only heat up at the same time and at the same temperature. which is kinda useless to me since I like to use a rectangle wrought iron pan to grill sandwiches and specifically bought this unit having being told that they connected in the centre to create even heat. Then... 12 inch centre element: the centre element doesn't heat up as fast as it should and is temperamental. One day it didn't even turn on and I had to use one of the smaller elements to cook my dinner. the day before that it cooked for short periods and would cut-out so I never really reached the temperature I need to get a fried coating. The smaller elements heat much faster than the centre element which I thought was the more powerful element. Also when boiling water the element only heated in the very centre and did cover the entire circumference of the 12 inch pot (which I checked was flat to the cooking surface). The Jenn-Air repair people sent out a repairman to fix it and he only made it worse. He came several times (the first couple of times they told me that there was nothing wrong with the unit) before they eventually agreed that I had a faulty unit and replaced it. This took 6 months. My new unit works a little bit better, but I still cannot use my centre 12 inch element. I even bought a special induction disc to see if I could start to use the element but again it works for a while and then starts to cycle on and off. So you cannot get a continuous heat in order to cook a meal to completion. I know it's not my pans, as I tried many different ones and the same thing keeps happening on the centre element and not to outer smaller ones. One more thing, the store where I purchased the cooktop agreed to replace the unit with another brand, but unfortunately for me the Jenn-air cooktop requires a smaller opening in the countertop (which I had made to fit) than ALL the other brands. So even thought I could have changed my cooktop, I couldn't because I would have had to cut my countertop to make room for another brand. If I had my time again, I would never buy Jenn-air.

I am comparing the Jenn-Air to the Bosch 800 series (new model). They are fairly similar in pricing, with slightly different feature sets and controls. Jenn-Air offers an auto boil function that monitors a pot of water so that it does not boil over and remains boiling. Bosch offers timers that actually shut down the element when the timer ends. There's also an "autochef" function that has pre-programmed frying settings. My local appliance store sells both and likes both. The Bosch features are probably a little cooler, but my impression is that they are both good choices. I've done a lot of research, and there are people who will always hate Jenn-Air (understandably), but Whirlpool has invested a lot of money in making the company a flagship brand for them. I may go Bosch just because the new Bosch ovens fit my needs better than any other brand in my price range, and buying both will make my overall cost less, but I'm still considering both. I would encourage looking at live models, if you can. Controls can be a huge personal preference you aren't aware of. I quite like the Jenn-Air slider control, but you may not.

Not really. I still don't use my large burner that much. After much searching I finally found a non-stick pan that triggers the large burner to cook somewhat evenly but it cost me $300.00 (of course). It was the ALL-clad 14 inch non-stick D5 fry pan. I really cannot bare the thought of having the service guy come and check out why my large burner wasn't cooking evenly so I have done the same and just dealt with it. I will never buy anything from Jenn-Air again. As you would know, every time a serviceman comes out, they don't seem to know anything about the unit, they pull it out of the countertop, they disrupt your day and they usually leave without any resolution. My guess is that after about 3-4 visits they give up and ask the company to replace the unit. My fear was that it's just a faulty design and this would fix nothing. So I would have wasted all the time and energy for nothing. good luck
