Replaced a 30 year old electric cooktop about 18 months ago with a
smooth ceramic one. Had trouble at the time finding a cooktop that
would fit in the oversized hole. Eventually ended up with Kitchenaid
that had a 1/4-3/8" overlap around all four sides. Yesterday it
cracked all the way across the short edge after a timer dropped onto
one corner. Question is: could the glass have had undue stress from
the weight load on the small overlap, making the crack likely to happen
again with the slightest drop? Was this a crack waiting to happen? We
have to decide whether to replace the glass (about $300) or go back to
an electric coil cooktop for about the same amount. Anyone have
experience with this?
