Symptom guide / cooktop
The glass top of the cooktop is cracked or chipped
A cracked glass top is not a surface to live with until it is convenient: the glass carries the pans, the crack grows with every heat cycle, and the honest answer is that the whole assembly is the repair rather than the pane. The safety list on this page opens with an instruction rather than a part: the glass is cracked and the appliance is still being used: stop using it, because the surface carries the weight of the pans and a crack propagates with every heat cycle - a pan that slips into it can tip hot food onto whoever is standing there [S1]. That is what puts the glass top of the cooktop is cracked or chipped in the medium-risk column, and it is why the machine has to be unplugged before any diagnosis. Once the machine is safe to work on, heat trapped under a pan that is too big, or too small is where the search starts — no part needed [S1], about 5 minutes. It is reported as a pot was dropped on the glass top, there is a chip at the edge that has started to spread, the glass cracked while it was cooling down, one zone stopped heating after the crack or is it safe to keep using a small crack?.

a pot was dropped on the glass topis it safe to keep using a small crack?
The fact that decides this whole page, and the source states it in its first line: the glass top can be replaced, but not the glass alone - the surface, the frame and the mounting are one assembly, so a crack is quoted as a panel rather than as a pane. A dropped pan is the usual cause, and the price depends on which of the three surfaces the machine has, which is why the source publishes three bands rather than one.
S1 prices the glass as an assembly rather than a pane, and gives installed bands by type: tempered glass $200-600, ceramic glass $400-1,000 and induction tops $300-1,000, with the labour portion at $50-300 for the one to two hours a swap takes

the glass cracked while it was cooling downa pot was dropped on the glass top
The cause that produces a crack with no impact behind it: glass that has just been used is at several hundred degrees, and a spill of cold water, a frozen item set down on a still-hot zone or a wet cloth on a warm surface changes its temperature faster than it can absorb. The crack often appears minutes later, while it is cooling, which is why the memory of the event is usually the spill rather than the break.
the same assembly bands apply: $200-600 tempered, $400-1,000 ceramic, $300-1,000 induction, plus $50-300 of labour

there is a chip at the edge that has started to spreadis it safe to keep using a small crack?
The source's answer to the question people actually ask is that a cracked glass top is not a repair you defer: the surface is load-bearing as well as decorative, the crack propagates every time the zone heats and cools, and a pan that slips into it can tip. It treats a small crack as the same decision as a large one, taken earlier - which is the honest position when the repair is a panel either way.
no separate figure for a chip repair exists because there is none: S1 treats any breach of the surface as the assembly replacement, priced at $200-1,000 installed by surface type

one zone stopped heating after the crack
The question the source says decides whether the replacement is worth doing at all: if a zone stopped heating after the crack, the surface is not the only casualty - the element, the wiring or the switch under it can be too, and a swap that does not fix the zone is a panel bought for nothing. S2 is the page that prices that side of the appliance, and its own number is the useful one here: a cooktop repair medians $339 across 122 completed jobs, so the diagnosis is worth having before the glass is ordered.
S2 prices the repair side of this appliance from completed jobs: burner $381 across 79 jobs and element repairs that come to a $339 median with the middle half at $255-530 across 122 cooktop repairs; no part-only figures are published
Repair or replace?
The verdict
Find out what is under the glass before ordering a panel, because that is what decides the whole job: a top that cracked from an impact with everything below it working is a straightforward replacement, while a zone that stopped heating after the crack means the element or the wiring went with it and the panel may be money spent on the wrong fault. If the machine is mid-range or better, under about ten years old and otherwise sound, the replacement restores a $700-2,000 appliance for a few hundred dollars. If it is a budget machine at the end of its life, the source's advice is the same as this site's: put the $99 toward a new one. [S1]
Two published rows from the same publisher sit behind this page and neither is a cut of the other, so they are named separately and never added together or averaged into one figure. The headline band above, $255 to $530 around a $339 median, is the middle half of 122 completed cooktop repairs from the glass-top page, and that page says in its own words that the figure covers all completed cooktop repairs rather than glass swaps alone, with glass assembly work sitting toward the upper half of the band because the panel is the expensive half of the invoice. The symptom row this page turns on - cracked glass at a $644 median across 16 repairs, middle half $380 to $764 - is published on a second page from the same publisher that rests on a different and larger set, 317 completed cooktop repairs with its own $375 median and $295 to $487 middle half. The 16 cracked-glass jobs are therefore not a subset of the 122 and the two counts cannot be summed; the publisher's own minimum-sample rule is why the smaller set is not broken down by symptom at all. The $99 diagnostic is published on both pages as the same standard visit, applied to the repair. That symptom row is printed above as its own labelled band with its own 16-job count and its own middle half, so the reader sees the cracked-glass figure beside the all-cooktop band rather than inside it.
The comparison is a panel at $200-1,000 against a machine worth $700-2,000, and the deciding factor is not the crack but the age and the range: on a mid-range cooktop under ten years old the panel is a fraction of the replacement, and on a budget top with a second fault it is most of the way to a new appliance. Neither source prices installation and haul-away for a new cooktop separately, so that figure is left out rather than estimated.
the source's own framing of the decision: replacing the glass makes clear sense when the appliance is mid-range or better, under about ten years old and everything under the glass still works, because it restores a $700-2,000 appliance for a few hundred dollars. That $700-2,000 range is the machine value it uses, not a new-machine price list, and it is what the comparison on this page means

there is a chip at the edge that has started to spreadthe glass cracked while it was cooling down
The prevention the source puts at the end of the page, and the cause behind the cracks that have no single event behind them: heat that is trapped on one spot - by a pan wider than the zone, by an empty pan left to heat, or by a base that does not sit flat - stresses the surface unevenly every time the machine is used. The advice is to match the pan to the zone and to keep pot bottoms clean and dry, because both of those stop heat concentrating where the glass is weakest.
