It carries the pans, it holds the assembly together, and it is the only thing between a spill and the coils, boards and connectors underneath. That is why a crack is treated as a reason to stop rather than as a cosmetic problem, and why the repair includes looking at what is below before new glass goes over it. ### What we establish before anything is dismantled - Whether the part is available for your model, which on an older machine is the whole question - What it costs, in writing, before you decide - Whether anything has already reached the electronics - Whether the honest answer is that this machine is not worth the glass ### How to avoid the next one Deal with sugary boil-overs while the surface is still hot, using a scraper rather than waiting — sugar etches ceramic permanently. Keep pan bases flat, because a warped base concentrates heat on two points. And do not use the surface as a worktop for anything heavy, which is how most impact cracks actually happen. ### What the repair costs Glass replacement starts at $295 including labor, with the glass itself quoted for your specific model once availability is confirmed. If it cannot be had, you pay the diagnostic and nothing more. What this involves Stop using it and switch it off at the breaker until it is seen The seal and the frame checked as well as the glass Availability established before anything is dismantled Establish whether it is safe as it stands A hairline at the edge and a crack across a zone are not the same risk. What decides it is whether liquid can now reach the electronics and whether the glass is still supporting itself, and both of those are looked at before anything else. Confirm the part exists before opening anything Glass is model-specific and, on an older machine, it is the part most likely to be gone. We establish availability first, because a cooktop dismantled around a part that cannot be had is a worse position than a cracked cooktop. Check what is underneath If anything has already got past the crack, the boards, the connectors and the coils below need looking at while the surface is off. Replacing glass over corroded electronics buys a few weeks. Seal it back properly The bead around the edge is what keeps the next spill out, and on a stone counter the fit has to be right the first time. It is not a step to rush.

We would say no, and this is one of the few places on this site where we are not going to soften it. The glass is structural and it is the seal against liquid reaching live electronics beneath. A small crack is a path, and the failure it leads to is not a cooking failure. Switch it off at the breaker and have it looked at. ### What actually cracks these? Impact is the obvious one — a heavy pan set down hard, something dropped from a cabinet above. The less obvious one is thermal: a hot zone and cold liquid, or a pan whose base has warped so it sits on two points instead of across the zone. And a chip at the edge, from an installation that was a fraction tight, will propagate over years. ### Is it worth it, or should I replace the cooktop? It depends on the machine and we will tell you straight. On a recent induction cooktop with a healthy set of boards, glass is worth doing. On an older radiant top where the glass is scarce and the switches are aging, it often is not, and we would rather say that than take the job. What we do not do is dismantle first and discuss it afterwards. ### The surface is not cracked but the ring has gone rough. That is usually sugar. Anything sugary that boils over onto a hot ceramic surface etches it, and once etched it is permanent — it does not come off with cleaning because there is nothing sitting on top. It is cosmetic rather than dangerous, and worth knowing about because the way to avoid it is to deal with a sugar spill while it is hot rather than afterwards. --- **[Read full article: Cooktop glass replacement](https://bertazzonimiami.support/services/cooktop-glass-replacement/)**
