Product review (2 stars): Replacing Whirlpool with GE is not smooth sailing
Unfortunately, GE 30 inch cooktop runs 'smaller' than Whirlpool cooktop I was replacing, My countertop cutout is 1/4 inch larger for Whirlpool cooktop, so GE would've 'fallen thru' & has different downdraft configuration. Because my basement ceiling below is drywalled, re-doing the venting to fit GE downdraft (from a Whirlpool/Jennaire config) would've required replacing, repainting drywall. So I had to abort the install & return the GE cooktop & buy a Kitchenaid cooktop instead, for more money & in black. I liked that GE cooktop was white to match my existing appliances & had 'merge a burner' feature. Having a cooktop sizing comparison or information that GE vs Whirlpool/Jennaire sizing are different would've been very helpful & appreciated so I didn't waste my time & Amazon installer's time to end  up aborting the install. And Amazon doesn't sell Kitchenaid so I bought it from a brick and mortar store.
