Cooktop glass surface cracked (unit is powered)

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Turn every cooking-zone control to Off, stop adding cookware or food, and keep everyone away from the cracked surface while the unit remains hot or powered.

   Expected result: Confirm that no zone is visibly active, no cookware or liquid is resting on the crack, and the crack is not being touched to move a pan or test the surface.

   Next step: Leave the cooktop and, if applicable, the range oven unused; wait for a safe cool-down before making a no-contact record and arranging service.

   Stop if: Do not turn another zone on, slide cookware across the crack, or use a cover as permission to keep cooking.

   Why this matters

   Why: A broken or cracked surface must not be operated. Continuing heat or contact can worsen the damage and can expose people to burns, cuts, or electrical hazards.

2. Check 2

   From a safe position, observe whether the controls respond normally after being turned Off and whether there is smoke, arcing, burning odor, unusual sound, liquid entry, or a protective device that trips; do not touch the crack, wiring, or hot surface.

   Expected result: Record normal control shutoff versus a control that remains active, a wet or open break, smoke or sparks, an odor, repeated power interruption, or an unusual gas symptom.

   Next step: For an abnormal symptom, move away and use only a safely accessible documented disconnect or fuel shutoff if the owner's instructions permit it; otherwise call qualified or emergency help without approaching the appliance.

   Stop if: Do not restore power, handle wet controls, open panels, reach behind the unit, or investigate gas or electrical symptoms yourself.

   Why this matters

   Why: A control or electrical symptom means the problem may extend beyond the glass. Liquid or cleaner can penetrate broken glass, and abnormal heat, smoke, or arcing raises the urgency above a routine replacement appointment.

3. Check 3

   Let the cooktop cool completely after all controls are Off, using only the model's residual-heat indication as a guide and keeping hands and objects away from the damaged area.

   Expected result: Note whether the hot-surface or residual-heat indication clears, whether the glass is still radiating heat, and whether any fragment or edge has shifted without being touched.

   Next step: Once cool, continue with a no-contact visual record only; if heat remains unexpectedly or the crack changes, stop and tell the technician.

   Stop if: Do not pour water on the surface, wipe it while hot, place a cold pan over the break, or touch a sharp or loose fragment.

   Why this matters

   Why: Controls being Off does not mean the glass is immediately cool. Touching or moving cookware on a hot cracked surface can cause burns or disturb fragile fragments.

4. Check 4

   After cooling, photograph the entire cooktop and the crack from above and a shallow angle without cleaning, pressing, scraping, lifting, or removing trim; record the complete model and serial information from an accessible label or owner documentation.

   Expected result: Record whether the damage is a line, branching split, chip, pit, loose edge, or visible opening, and whether it reaches a cooking zone, control area, perimeter seal, or vent.

   Next step: Send the photos, model, appliance type, and control behavior to qualified appliance service; do not order a generic panel or attempt to make the crack look cosmetic.

   Stop if: Do not clean a broken surface, use abrasive products or a scraper, remove the glass, or handle fragments with bare hands.

   Why this matters

   Why: A crack, chip, pit, or indentation keeps the appliance in the service category. The model and appliance configuration determine whether the repair uses a glass surface or a larger cooktop assembly and what disconnect procedure is appropriate.

5. Check 5

   If the controls cannot turn the unit off or the crack has liquid entry or an electrical symptom, use the owner's documented power-disconnect method only when the disconnect is safely accessible, dry, cool, and away from the damaged surface.

   Expected result: Confirm whether all indicators and heating activity stop, whether the disconnect point was reachable without moving the appliance, and whether any smoke, arcing, heat, or odor continues.

   Next step: Keep the appliance out of use and arrange qualified service; leave the area and contact emergency help if smoke, fire, active arcing, or immediate danger persists.

   Stop if: Do not reach behind the appliance, open an electrical panel, pull wet plugs, remove covers, or restore power to test the crack.

   Why this matters

   Why: Removing power can stop an active appliance, but an inaccessible, wet, hot, or abnormal disconnect point is not a safe homeowner task. Continued symptoms require professional or emergency response.

6. Check 6

   After a qualified technician repairs or replaces the model-specific glass surface or cooktop assembly, inspect the finished surface visually and follow the technician's and owner's instructions for any controlled function check.

   Expected result: Confirm that the surface is intact and seated, no sharp edges or gaps remain, all controls are normal, and any liquid-entry or electrical concern has been addressed before operation is released.

   Next step: Use the cooktop only after the technician or manufacturer clears it and the owner's instructions permit operation; report any new crack, gap, heat, smell, or control fault immediately.

   Stop if: Do not cook on a repaired surface with a new crack, loose trim, visible gap, unresolved heat or control issue, or any electrical or gas symptom.

   Why this matters

   Why: Removing the visible crack is not enough to verify a safe repair if the assembly, seals, controls, heating components, or wiring were affected.
