    I presume when you title says "glass top oven" and description says "glass top stove" you mean a standard glass top range - with the burners (usually 4) embedded in the glass top ?


    First, google the following search phrase combined with your full model number (including any letters) to see if there have been any recalls on your model - Frigidaire glass top range recalls - there has been at least one FRigidaire/Kenmore glasstop range recall for the glasstops.


    If not, make sure not covered under original or any supplemental warranty you may have bought - if so call for warranty service.


    As far as causing it - yes there are quite a few things that can cause this, including a significant scratch from dragging something with rough or sharp bottom across it (especially over one of the burners), using knives to cut on it like a cutting board, letting the burner run hot without a pan on it or letting pan go dry, using pots or pans that are not flat on the bottom so there are only a couple of small contact points with the glasstop, using abrasive cleaner on it rather than the special cooktop/acrylic type cleaner provided with it, letting food spillage accumulate and carbonize on it which cause a hot spot and eventually cracking, and obviously dropping something on it which cracks it - maybe only a microcrack at first but then travels with temperature variations. Dropping cold water/ice on hot surface will also do it, as will a really out of alignment range body so the glass top is crimped in the framing (has to be pretty bad to affect this). From my limited experience, dropping heavy pot or pan on it and letting food carbonize on the burner are primary causes of cracking.

    The food burnt onto it takes a bit of explaining - it concentrates the heat at that spot because the carbonized food acts as an insulator so the heat from the embedded burner cannot transfer to the pot (same issue as food burned onto an oven element causing it to burn through), and also the carbon forms a high spot, so the pan no longer sits across the whole burner but only at a couple of very small points, so burner element can overheat, thereby overstressing the glass.
