Smell gas? Get everyone out first. No gas: switch the breaker off

A cracked top is urgent in the sense that it must not be used at all. Leave every zone off, keep liquids away, and switch off the breaker if anything got in or sparked. Replacement glass is ordered by model number, so find the label before you book.

What it
usually means.

The top of a radiant or induction cooktop is a single sheet of glass-ceramic resting in a frame over the counter cutout, with the elements or coils directly beneath it and the wiring below those. A crack breaks the seal that keeps spills away from all of that, and a cracked sheet can split further as it heats. Glass is never patched; it is replaced as a part matched to the model, and on many cooktops it comes as a top assembly with its frame. Some edge chips start at the counter itself: an opening cut too tight or a top forced into place can stress the glass at its corners.

Answer these first

01

Is it a crack you can feel with a fingernail, or a scratch, a ring or a stain?
02

Does the line cross a cooking zone, or stay at an edge or corner?
03

Did it show up after something was dropped, a pan boiled dry, or the counter was worked on?
04

Has any liquid run into the crack?
05

Is it a radiant top with glowing rings, or an induction top that stays dark?

Glass cooktop cracked: 5 checks, and none of them costs anything.

01

Stop using the cooktop now, including the zones far from the crack.

02

If liquid has reached the crack or anything sparks, hums or smells, turn off the cooktop's breaker.

03

Keep water and spray cleaners away from the glass until it is replaced.

Also worth checking

  • When the top is cold, draw a fingernail across the line; a crack catches it, a surface mark does not.
  • Photograph the crack and the model label, which is often under the burner box or on a card in the cabinet below.

The causes,
cheapest first.

6 things glass cooktop cracked turns out to be, from scratch or mineral ring that only looks like a crack to pressure from a tight counter cutout.

The cost guide
  1. 01 no repair

    Scratch or mineral ring that only looks like a crack

    Marks from aluminum pans, hard-water rings and fine scratches look like lines but do not catch a fingernail. A glass-top cleaner lifts most of them.

    No repair: check it yourself
  2. 02 low

    Sugar or melted plastic pulling out a flake

    Sugar and plastic bond to hot glass and can tear a flake away as they cool. A small pit outside the zones may only need watching; one inside a zone is inspected before the top is used again.

    Fixed by glass top replacement
  3. 03 low to moderate

    Element under the glass shorted by liquid

    Liquid that reaches a radiant element through the crack can short it. Once new glass is fitted, the parts underneath are tested before the top goes back in service.

    Fixed by radiant element repair See cooktop element not heating
  4. 04 moderate to highest

    Impact from a dropped pot, lid or jar

    A heavy lid, or a jar knocked from a cabinet above, can crack the sheet in one blow, often in a star spreading out from the point of impact.

    Fixed by glass top replacement
  5. 05 moderate to highest

    Thermal shock from a pan boiled dry

    An empty pan left on high heats one patch far past the rest of the sheet, and the stress can split the glass straight across that zone.

    Fixed by glass top replacement
  6. 06 varies

    Pressure from a tight counter cutout

    If the countertop opening is undersized or out of square, the frame presses on the glass as it expands with heat. A crack that starts at a corner with no impact mark points here, and the cutout is checked before new glass goes in.

Questions about
glass cooktop cracked.

Can a cracked glass cooktop be repaired instead of replaced?
No. Sealants and patch kits cannot restore the strength or the seal of glass-ceramic, and a patched top can still split under heat. The sheet, or the whole top assembly, is replaced.
Does a small chip on the rim matter as much as a crack across a zone?
An edge chip that stays at the rim carries less risk, but it still breaks the seal and can grow into a crack. Keep it dry, stop cooking on it, and have it judged in person.
Does the cooktop have to come out of the counter to change the glass?
Often, at least partly, because the glass sits in a frame over the cutout. Power is disconnected first, the top is lifted, and everything is reconnected afterward.
Could the countertop itself have caused the crack?
Occasionally. A cutout that is too tight lets the frame squeeze the glass as it heats. A crack that begins at a corner with no sign of impact is the usual clue.
