Cooktop glass surface cracked (crack is visible)

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

1. Check 1

   Turn every cooktop control off, remove hands and cookware from the damaged area only when it is safe to do so, and keep children, pets, and loose objects away from the surface while it cools.

   Expected result: Confirm that no cooking zone remains visibly active, the surface is no longer being heated, and no person needs to cross the damaged area to reach a control.

   Next step: Leave the cooktop unused and proceed only with a no-touch visual record after it is cool; arrange appliance service for the repair decision.

   Stop if: Do not touch the crack, move a pan across it, or keep cooking on an apparently unaffected zone.

   Why this matters

   Why: A visible crack is not an ordinary operating issue. Continued heat or cookware contact can stress the damaged surface, while a hot cracked surface adds burn and fragment risk.

2. Check 2

   After the cooktop has cooled completely, inspect the surface from above and from a shallow angle without wiping, scraping, pressing, or running a finger over the damaged area; photograph the visible line, chip, pit, or branching pattern.

   Expected result: Record whether the mark is a continuous crack through the surface, a chip or pit, a raised or sharp fragment, or a mark that cannot be distinguished safely from a crack.

   Next step: Treat an uncertain or damaged mark as a crack until the manufacturer or technician confirms otherwise; keep the appliance off and include the photographs with the service request.

   Stop if: Do not clean a broken or cracked surface, use a razor or scraper to test it, press on the glass, or pick up fragments with bare hands.

   Why this matters

   Why: A true crack or pit keeps the appliance in the stop-use and service category. An uncertain mark cannot be safely cleared by forceful cleaning, and a sharp or loose fragment adds an immediate cut hazard.

3. Check 3

   From a safe position, document whether the crack extends toward a heating zone, control area, edge, seal, or vent, and whether there are visible wet spots, residue, fragments, or an opening through which a spill could enter; do not move the appliance or remove trim.

   Expected result: Note a stable hairline, a spreading or branching crack, a separated edge, liquid or cleaner near the break, a loose shard, or damage crossing a control or burner area.

   Next step: Keep the appliance isolated from use and tell the technician exactly where the damage and any liquid entry are located; do not attempt to dry an opening by operating a burner or oven.

   Stop if: Do not pour water or cleaner on the surface, touch fragments, open the appliance cabinet, or continue if there is smoke, smell, arcing, or an active electrical symptom.

   Why this matters

   Why: A crack that is spreading, open, wet, sharp, or near controls or heating components raises the urgency and cannot be managed with a cosmetic repair. Manufacturer safety guidance specifically warns that spillovers or cleaning solution can penetrate broken glass.

4. Check 4

   Record the appliance model and serial information, whether it is a standalone cooktop or a range, and whether it is radiant, induction, or gas-on-glass; photograph the entire surface and the rating label without removing panels.

   Expected result: Confirm whether the oven is part of the same range, whether the crack is near a control or vent, and whether the model information is complete and legible.

   Next step: Provide the model, configuration, photographs, and damage location to the manufacturer or qualified appliance technician and wait for repair guidance; do not order a generic glass panel.

   Stop if: Do not lift the cooktop, remove screws, disconnect wiring or gas, or use the oven to avoid the cracked surface unless the exact manufacturer and technician instructions explicitly address the repair.

   Why this matters

   Why: The replacement glass or cooktop assembly and the safe isolation method are model-specific. On a range, oven heat may vent toward the damaged cooktop, so the oven cannot be assumed safe to use while the crack remains.

5. Check 5

   If a control remains active, liquid has entered the break, or another electrical symptom appears, use the appliance owner's documented disconnect method only when the switch or disconnect is safely accessible without touching the damaged surface, hot parts, water, or exposed wiring.

   Expected result: Record whether all heat and indicator activity stops, whether the disconnect is accessible and dry, and whether smoke, odor, arcing, or a tripped protective device is present.

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

   Stop if: Do not reach behind the appliance, handle wet controls, open an electrical panel, remove covers, or restore power to test the cracked surface.

   Why this matters

   Why: Disconnecting a damaged appliance can reduce ongoing electrical exposure, but an inaccessible, wet, hot, or abnormal disconnect point is not a homeowner repair task. A persistent electrical symptom requires urgent professional assessment.

6. Check 6

   After a qualified technician has repaired or replaced 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 repaired surface is intact, seated, and free of sharp edges or visible gaps, and that the technician has addressed any liquid-entry, control, heating, or vent concerns.

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

   Stop if: Do not cook on a surface with a new crack, sharp edge, loose trim, visible gap, or unresolved electrical or gas symptom.

   Why this matters

   Why: A replacement surface is not verified merely because the crack is no longer visible; the assembly, seals, controls, and appliance-specific safety functions must be returned to the manufacturer's intended condition.
