I did a very brief search for a new glass for that unit and came up with nothing, again I did not search very hard. You can look up the dimensions of your current unit and determine the cut out size needed for a replacement unit. Most of these units have standard sizes and you should not need to cut a new "hole" with 36" unit. It is possible the cutout may need to be modified slightly mostly depending upon the ventilation needs of the replacement unit. Point here being you will not need to replace your counter top in order to replace your cook top. Now is a good time to consider induction!

If you have any consideration of repairing it instead of replacing ... there are multiple model hits at SearsParts.

First two have chrome trim at top & bottom (replacement glass available $1252.51 from Sears, $1098.70 from another source), other two have black trim (replacement glass $1519.19 from Sears, $987.25 from another source).

Electrolux/Frigidaire manufactured that model for Sears/Kenmore.

If you are open to it, I would highly recommend buying an induction cooktop. I would never go back to gas or regular electric. So much faster, more control, doesn't pump heat into your room, etc, etc. I am waiting for the slide in range in our vacation house to break so I can justify changing to an induction slide in range. I might do like you and break it myself.

PS--thanks for the comments--I forgot how helpful this site is--haven't been here in while

had hard time getting the model number off the "burner box" under the cooktop at first

so didn't know exactly what of 3 possible models it could be...

I went online and found a replacement glass cooktop w/the same digital/touch controls on side-Dadoes gave two of the parts I found--

one I found with Sears parts direct was over 1500

one @Easy Appliance Parts website was 1092--

i was surprised both numbers I called had people who answered pretty promptly--

Easy Appliance parts was in Canada. And the part number shows Frigidaire/Kenmore

what place had the one under 1K--Dadoes?

i thought about an induction cooktop--but not sure if one would fit my countertop cutout

are dimensions for 36" induction that much different than radiant electric?

I have my cooktop on island w/o over underneath--that is further along the island

36" is 36", a slight modification could be necessary depending on the cook top you choose but nothing more. As you have discovered repair parts are almost or more than replacement. Go shopping and stay away from Samsung!

My luck lately has not been so good--a "slight" modification could come out cracked granite

I like the fact that the touch controls are all on right side--and this has lot of option like a timer and turbo-boil feature that less expensive cooktops don't...

I have a custom made chopping block I ordered on Etsy when we bought this house to protect the cooktop and prevent just this damage--unfortunately I did something stupid when the chopping block wasn't there...I can slide it down and use two burners and have access to the controls much easier than a different design--and keeping that chopping block helps preserve the rest of the cooktop too...

I can afford the money for replacing the top vs buying new--

but the comments about Induction cooktop have sort of made me rethink

that wasn't really on my mind when I was looking for info about replacing what I have...

I saw enough bad ratings looking at Home Depot and AJ Madison's websites that I know to stay away from them... Washers too...

consider Bosch. Great induction cooktops.

Let me address the fitment issue again. It is not an issue. Home appliance have standard sizes and generally speaking they all fit and are interchangeable with other appliances of the same dimensions. I say slight modification because appliances today are electronic instead of mechanical. Meaning circuit boards needs to be kept cool under the heat it makes in order to cook your food. so insuring you have enough clearance for proper ventilation is essential to get the most life out of the product. People who cut granite can come in and modify the "hole" with the right tools and make sure you have the proper dimensions to accommodate your new cook top. This will be true even if you go back with an electric resistance cook top unless you manage to find the exact make and model of the one you have now.

Electrical requirements: Most residential induction cook tops will operate fine on a 30 AMP circuit. If you keep tripping the circuit you will need to upgrade the wiring and replace with a 40 AMP breaker. Generally it is not an issue unless your running all 5 Hobs at once and attempting to do so at maximum. 40 AMPS are what most manufacturers print in the specifications, so if you don't have a 40 AMP circuit or higher, I do recommend you get it installed. Remember this is just not pulling out the 30 AMP breaker and replacing with a 40 AMP. The wiring needs to be the proper gauge to accommodate 40 AMPS

Cooking Utensils: Yes you will need to go shopping for new pots and pans. General rule if a magnet will stick to the bottom, it will work on the cook top. Unlike electric resistance most induction cook tops sense the size of the pan and will not operate if you don't cover enough of the magnetic coil. So I recommend purchasing individual pots and pans to insure they work instead of just buying a set.

Cook top Layout: There are as many designs as you can shake a stick at. All you need do is search and you will most likely find a unit that satisfies your needs. They have units that are all touch screen and ones with knobs. On the left, right and bottom. Just about any configuration you can think of someone has it covered.

Learning curve: There is a slight learning curve, my recommendation is to not set the controls to maximum for anything until you are comfortable with it. Unlike electric resistance the heat comes on very fast and you can burn things quite easily. Remember you are heating the pan directly. The heat does not have to travel from the cook top surface and then to the pan, This offers an unprecedented level of control and also the ability to screw up in dramatic fashion as well. Just take it slow and I promise you will come to love it. I would never go back to electric resistance.

Reliability: Unfortunately nothing lasts the way it used to. I never used to buy warranties, however now I do purchase them on select appliances. My latest induction cook top is no exception. I generally purchase the longest one they offer. This is because they are not built to last. They are built to break so you have to buy a new one within a few years. At least with the warranty it is a minor inconvenience instead of a major issue. Wolf can break just as easily as the GE. Name makes little difference now a days. However I will recommend Miele as a starting point.

I hope this helps...happy shopping!

I called Ferguson's today to see if could get someone to point out units that would work with our size opening but gus who works in their kitchen appliance Dept was not there...

I think most new units require a SMALLER opening vs the larger one used for current unit

having to add support inside the box is going to require some carpentry skills

We went to local appliance store our electrician's receptionist recommeneded--

Electrical company would not come pull the unit for us to check the cutout (for a fee of course)

Sears won't come out because it is not a "repair"

the salesman at appliance store looked but I think the units Bosch and LG he found are not going to work

I found a Kitchenaid on Home Depot site that says it takes cutout that is basically same size as what we have---

so likely tomorrow will go to Home Depot and see if their people think it will fit...

Followup--we went to Home Depot--ordered that KitchenAide which had to be shipped and took more than 10 days to arrive--we told saleswoman old/cracked one would have to be removed and size of opening checked for the new one's installation BEFORE we would "take delivery" of the one we ordered--

she was like NO PROBLEM--we paid to have the broken one disposed of--but didn't pay extra for the installation...she didn't say there was an extra charge for installing it

but we would have paid for it because obviously we aren't doing it outselves.

The delivery came on time--company sent notice Monday and then another on day of deliver--today--

two guys brought it out--could not take out the old one NOR COULD THEY INSTALL THE NEW ONE--they were just delivering it...

BFD--Home Depot was not really helpful until my husband got pretty disgusted w/the woman on the phone (from the FLOORING Dept) because everyone in appliances couldn't take the call...

finally got store mgr to call back...

he wanted us to reschedule delivery of cooktop (and take delivery) before we scheduled for an actual installation...we said no thank you...

so we have called for rede livery Tuesday and the installation company is supposed to call tomorrow about the actual installation...

in the mean time, I called the construction company that did the kitchen remodel for prior owners and got name of the electricians they used to do theit installs...

called them and they had someone coming near us today--

they are having him come by to take out the broken unit and give us idea if the one we ordered will fit...will have the installation diagram for the new cooktop w/dimensions

I never imagined this would be such a big problem...

will pay for the service call and maybe something extra but at this point I just want info from someone who knows what they are doing...
