Direct answer: If your Whirlpool cooktop glass is truly cracked, stop using that burner and usually stop using the whole cooktop until the glass top is replaced. A real crack can spread with heat, let spills reach live parts, and turn a small problem into a shock or shatter risk.
Most likely: Most often this is impact damage from a dropped pan, a hard edge strike, or heat stress around an already weakened spot. On a glass-ceramic top, there is no safe patch that restores normal use.
First make sure you are looking at an actual crack and not a metal mark, baked-on residue, or a scratch in the surface. If you can catch a fingernail in the line, see branching lines, or notice a chip at the edge, treat it as failed glass. Reality check: even a small crack usually means the top is done. Common wrong move: running it 'just one more time' to see if it still heats.
Don’t start with: Do not start with glue, epoxy, tape, or continued test cooking. Those are common time-wasters and they do not make a cracked cooktop safe.
A thin line runs across the top and may be easiest to see in side light. Your fingernail often catches on it.
Start here: Clean the area first, then check whether the line is raised residue, a shallow scratch, or a true crack you can feel.
A corner or edge has a nick, flake, or small missing section, sometimes after a pan strike.
Start here: Treat edge chips seriously. Edge damage is where heat cycling often turns a chip into a spreading crack.
You see a center impact point with several lines running outward.
Start here: Stop using the cooktop. That pattern is classic impact damage and the glass top needs replacement.
The burner works, but the glass has a visible crack or chipped area.
Start here: Do not assume it is safe because it still heats. Function does not cancel the shock and shatter risk.
A pan edge, spice jar, or heavy lid can chip or crack glass-ceramic instantly, especially if the damage has a clear strike point.
Quick check: Look for a small pit, chip, or star pattern where the damage started.
A small chip or scratch can spread after repeated heating and cooling, especially near a burner zone.
Quick check: Look for a crack that starts at an edge, corner, or older nick and runs inward.
Metal transfer, burned-on residue, and some scratches can look like a crack until you clean and inspect closely.
Quick check: With the cooktop cool, clean the line and see whether it changes, fades, or disappears.
Sometimes the top was stressed earlier and the crack becomes obvious later during normal use or cleaning.
Quick check: Check for older scuffs, a known pan drop, or a line that has slowly lengthened over time.
A lot of homeowners are looking at pan marks, baked-on residue, or a scratch. You want to separate cosmetic surface damage from failed glass before doing anything else.
Next move: If the mark wipes away or turns out to be only a faint surface scuff, the glass is not cracked. Keep monitoring it and avoid abrasive cleaning. If the line stays put, catches a fingernail, or starts from a chip, treat it as cracked glass.
What to conclude: You have separated harmless surface marking from a failed cooktop top.
Once the glass is cracked, the main job is preventing heat, spills, and pressure from making it worse or reaching live components below.
Next move: The area is stabilized and you have reduced the chance of a bigger break or an electrical short from a spill. If the glass is actively separating, sparking, or crumbling, leave power off and arrange service right away.
What to conclude: A cracked cooktop top is now a safety issue first, not just a cosmetic issue.
A tiny edge nick and a long burner-area crack are not the same. This tells you whether there is any short-term gray area or whether replacement is the only sensible path.
Next move: If you find only a superficial edge nick with no crack line, you may have time to schedule repair before it worsens, but it is still not something to ignore. If the crack crosses a burner zone, branches, or reaches the control area, replacement of the cooktop glass top is the practical fix.
Replacing a cooktop glass top can be straightforward on some units, but it still involves lifting the unit, disconnecting power, and transferring cooktop components without damaging them.
Next move: If the damage appears limited to the top and the rest of the cooktop looks intact, replacement of the cooktop glass top is the supported repair path. If there is internal damage, wiring damage, or you cannot safely remove the unit, stop here and book service.
There is no durable field repair for cracked glass-ceramic cooktop tops. Once confirmed, the fix is replacement of the cooktop glass top assembly or replacement of the cooktop if parts or labor do not make sense.
A good result: The cooktop has an intact top again and can be tested for normal heating and control response.
If not: If the new top is installed and a burner, control, or indicator does not work correctly, stop and have the cooktop checked for hidden impact or spill damage.
What to conclude: A confirmed crack ends with replacement, not patching.

Usually no. Even if the burner still works, a true crack can spread with heat and let spills reach live parts below. The safe move is to stop using it until the top is replaced.
Clean the area first. A burn mark or metal transfer may fade or wipe away. A true crack usually catches a fingernail, reflects light differently, and may start from a chip or branch outward.
No practical patch restores normal safe use on a cooktop surface. Heat cycling and cookware weight make those fixes unreliable. A confirmed crack means replacing the cooktop glass top assembly.
The most common causes are impact from dropped cookware or another hard object, or heat stress that spreads from an older chip or weak spot.
A crack across a burner is more urgent, but an edge chip still matters because that is where cracks often start and spread. If the chip has any line running from it, treat it as failed glass.
If the damage is limited to the top and the components below are intact, the cooktop glass top assembly is usually the direct repair. If the impact also damaged supports, wiring, or controls, full replacement may make more sense.
