Cooktop Cutout Requirements:

• Width: 34-3/8" to 34-1/2". Your cutout is 34-1/2" so it will fit.
• Length: 19-13/16 to 19-15/16". Your cutout is 19-3/4 = 19-12/16" so it is TOO SHORT by 1/16".

Any of these would fit:

• Frigidaire Gallery GCCI3667AB 36'' Induction Cooktop
• Frigidaire Gallery FGIC3666TB 36'' Induction Cooktop
• Frigidaire FCCI3627AB 36'' Induction Cooktop

You can have the cutout expanded for several hundred dollars. No square corners please.

What is your countertop material?

Also make sure that the depth needed by the unit is available and not intersecting a drawer or internal support.

I have Corian counter tops so the installer was able to expand the opening to fit the new cooktop. What is your countertop material?

@wdccruise Thank you for responding. Is 1/16 too short? sorry I don't understand the installation process. The cooktop base is 19 5/16", which should fit the cutout right? And yeah frigidaire is the one I have right now, which I am looking to replace :) I'm also looking at https://www.samsung.com/ca/cooking-appliances/hobs/induction-hob-with-4-burners-nz36k7880ug-aa/

For this, the cutout seems to be bigger than the expected specs.

@Joseph Corlett, LLC Thank you, yes exploring those options and it does have round corners.

@kaseki thank you, the countertop is quartz and there's nothing below the cutout, no drawers no wall oven.

@BobH Yeah that's why I'm confused, based on that measurement the cooktop should fit just fine but don't understand why the expected cutout dimensions don't match in that case.

The recommended cutout dimensions are a little bigger to allow some adjustments in case the cutout is not square or the edges aren’t straight

"Quartz" is something that 'amateur' tools can work. So if the new unit is just a tad tight, it should be possible for a little careful sanding to ease installation. Where a 1/16th must be removed along 36-inches, then I'd recommend professional help. In all cases, stone dust is the enemy of drawer slides, even those not connected to the cavity. Either vacuum it as you work or mask nearby drawers and cabinet doors.

@BobH thank you, that's nice to know. how does it work when the cutout is slightly larger than the expected cutout dimensions? I'm also looking at this product, if LG doesn't workout https://www.samsung.com/ca/cooking-appliances/hobs/induction-hob-with-4-burners-nz36k7880ug-aa/

but for this the current cutout is a bit larger than the cutout dimensions mentioned in the manual.

@BobH: "On page 11 of the owners manual is states the depth of the cooktop base is exactly 19-5/16” so your cooktop will fit just fine."

If you assume that there really wasn't any reason for the manufacturer to specify a cutout depth of 19-13/16" to 19-15/16".

"I'm also looking at this [Samsung] product..."

Why not consider products that will fit instead of those that won't?

@wdccruise That makes sense, thank you. I'm looking for backup options in case the product that FITS goes out of stock or doesn't work as expected.

If the cutout is too big you will need to either change the cooktop to onne that fits or a new counter . IMO one more reason to not do cooktops too many variables . A nice freestanding range they come in simple sizes usually that will fit .

"I'm looking for backup options in case the product that FITS goes out of stock or doesn't work as expected."

Did you check out the three Frigidaire models I suggested earlier all of which fit?
