Cracked or Scratched KitchenAid Glass Cooktop: Keep Cooking or Stop?

A dropped pot, a heavy cast iron skillet, or sugar that cooked onto the surface can leave a mark on a glass-ceramic cooktop. Some marks are only cosmetic. Others are a real safety concern.

Marks that are usually cosmetic

• Light scratches that you can feel only barely with a fingernail
• Gray metallic streaks from pan bottoms
• Faint discoloration that wipes away with a cooktop cleaner

Marks that mean stop

• Any crack, even a thin line, that runs through the glass
• A chip or pit that exposes a rough or open edge
• A spot where the glass looks shattered but still holds together
• Glass that has lifted or no longer sits flat in its frame

A broken panel no longer seals the cooktop. Spilled liquid can run down to the wiring below, which risks a short or a shock when you touch the surface, and heating a damaged panel makes the crack grow.

What to do right away

1. Turn every zone off and wait for the glass to cool.
2. Shut the cooktop breaker at the panel if you can reach it safely.
3. Keep wet cloths away from the damaged area.
4. Take a photo and note the brand label under the edge or in the paperwork.

Repair or replace the glass

Cracks cannot be patched or sealed. The whole glass panel must be replaced, and on an older cooktop we will help you weigh that cost against a new unit. If the impact also bent the frame or hurt an element underneath, you will hear it from us before work starts.

Prevent the next one

Lift pans rather than sliding them, keep pan bottoms clean and flat, and remove sugary spills while warm with a razor scraper held at a shallow angle.

If you are unsure how bad a mark is, send us a photo and we will help you decide. Our cooktop repair page explains what we handle, and our coverage list shows the Houston neighborhoods we reach.
