A ceramic surface is a substantial one and is model-specific. Both start here because from the kitchen they can look identical — a zone that is not working — and the difference is established by measurement on the visit. Availability of the glass is confirmed before anything is booked, because on an older cooktop it sometimes decides against the repair altogether. ### What goes wrong on a radiant surface - **The element**, which fails open or fails under load — and the second reads perfectly fine cold. - **The infinite switch**, which meters the heat and which imitates an element exactly. - **The control**, when a zone will not hold a setting rather than being simply on or off. - **The glass**, from impact or from thermal shock, and it is the end of using the appliance until it is dealt with. ### The one rule A cracked ceramic surface goes off at the breaker and stays off. Not because the appliance will refuse — it may not — but because the glass is what stands between a spill and the wiring under it. There is no version of this where using one more zone for one more week is a reasonable risk. ### What it costs From $195. A switch is the bottom, an element the middle, and a ceramic surface the top — quoted separately once the part is confirmed available for your model. What this involves Element and switch told apart, because they share a symptom Glass availability confirmed before anything is booked A cracked surface goes off at the breaker and stays off Which zone, and how wrong Dead, stuck on full, or unable to hold a setting. The first two are usually the switch or the element; the third points at the control. One zone against all of them separates a part from a supply problem in a sentence. Measure the element under load An element that has opened is straightforward. One that is failing under load reads fine cold, which is why this is measured hot rather than assumed. The infinite switch What actually meters the heat on a radiant zone, and a common failure that imitates an element exactly. It is cheaper than the element, so it is measured first. Glass, and honesty about it A cracked or chipped surface is a replacement, it is model-specific, and availability sometimes decides against the repair. That is established before a booking rather than on the day. Two jobs, one band An element or a switch is a modest repair. A ceramic surface is a substantial one and is model-specific.

Can I keep using the other zones? No. On a radiant or induction cooktop the glass is a structural part of the appliance and it is what keeps liquid out of the electronics underneath. A crack, a chip at an edge, or a ring that has gone milky and rough are all reasons to switch it off at the breaker and leave it off until it is replaced. ### One zone will not turn down. That is usually the infinite switch, which is what meters the heat, rather than the element. It is the cheaper of the two and it is measured first for exactly that reason. ### Can the glass be replaced, or is it a new cooktop? It can be replaced, and whether it is worth it depends entirely on availability and on the machine. The surface is model-specific and on older units it is sometimes the thing that ends the conversation. We confirm the part exists before you book rather than after. ### What is that scratch from? Usually a pan dragged rather than lifted, or grit under one. Scratches are cosmetic and do not affect the appliance. What matters is a crack, which goes through, and a chip at an edge, which becomes a crack. --- **[Read full article: Cooktop surface & element repair](https://jennairmiami.support/services/cooktop-surface-and-element-repair/)**
