I can only provide data for the units in the table below (click to enlarge). In general, the newer Frigidaire units have higher power ratings than the older Kenmore units. However, present Kenmore units seem to have secret ratings, because I haven't been able to find any. Failure of Sears to provide Kenmore data led me to replace my failed Kenmore with Frigidaire. (These are all nominal 36-inch units; if you are looking for 30-inch units, both Electrolux and Frigidaire websites should have all of the relevant parameters.) Electrolux manufactures Frigidaire induction cooktops, and, at least historically, Kenmore induction cooktops. You also need to compare cutout dimensions to avoid any installation complexity.

The power ratings of your older Kenmore may be discoverable by searching for the parameters of the older Electrolux Icon, as the Kenmore models at that time were nearly exact clones of the Electrolux.

There is information about wattage for each cooking unit on the Sears website. What I can't find is the same information for the old cooktop.

If a reasonable guess will do, you might assume that a given size Kenmore hob from the same general model year is the same power, whether in a 36-inch cooktop as I list above or in a 30-inch cooktop.

spguilford: Thanks for reporting that Sears now has the data on their website. I'll have to augment my table, as these [probably] also fit the standard E'lux cutout.

I have same cutout issue as you, 8 year old 36" Electrolux induction I can't rely on. When new part was being installed I observed corrosion & will not be repairing this unit. I'm getting additional error codes. Dilemma is filling cutout. I did find a Verona that looks as though it may fit, documentation says 3 cooling fans (does that mean noise?). I am reluctant to go with same Electrolux/ Fridgedaire manufacturer,

My suspicion is that the battle to make these cooktops thinner for convenience of cabinet utilization is the enemy of making them more reliable with better cooling and higher specification parts, thereby tending to cancel out any net gain in lifetime. However, we don't know yet what the apparent lifetime of recently produced units is. I have decided to just treat them as five-year leases and buy the lowest cost unit that provides the necessary functionality, and that fits the original Kenmore sized counter cutout.

As you may deduce from my table above, the Bosch will cover the hole, and there may be other brands that also do so. For the Bosch, one [only!] need reinforce the right and left ends of the cutout to correct the longer Kenmore cutout size. There are likely several ways to do this that depend on your cabinet and counter surface design. The Bosch top otherwise overlaps the counter so these changes should not be visible, and should not require stone cementing.

It is also possible, and I believe some have done this, to have a stainless steel frame fabricated that carries the load from the recommended cutout size to the actual cutout edges. This can in principle allow almost any make and model to be used.

I'll probably end up getting the Fridgedaire because I know very little about Verona brand as far as repairs & the Bosch has that flange/flap.
