Glass-ceramic cooktop cracked or chipped (radiant or induction): shut it down and quote the top

A cracked glass-ceramic top is a stop-use condition: spills can reach live elements and wiring, and heating can make the crack run and the surface break. The repair is a replacement top (usually the glass assembly, sometimes with elements) by a technician. Do not seal or glue the crack. Scratches, by contrast, are cosmetic and do not affect operation.

Before you start

Stop using the cooktop and turn off its breaker (or unplug it) as soon as a crack is found
Do not wipe liquid into a crack or use the surface as a work area until it is replaced
Do not fill the crack with epoxy or adhesive and return the cooktop to service
On a range, the oven may share the breaker; keep the whole appliance off until it is made safe

Ranges and wall ovens: reading F-codes and F#E# codes (GE, Whirlpool family) and when a reset is safe

Oven F-codes point to a circuit: temperature sensor, door lock, keypad or control. GE ovens show F plus a number; Whirlpool-family ovens show F#E#. Both makers tell owners to clear the display, cut power at the breaker for a short time and watch whether the code returns. A code that returns is a real fault. An over-temperature code is a safety stop: do not keep using the oven.

Oven door glass cracked or shattered: make it safe, document it, and quote the door glass

Oven doors use tempered glass, which breaks into small pebbles instead of shards. Earlier damage (a chip from a rack, a knock with a pan, a scratch) can weaken it so it fails later, even when the oven is cold. A cracked panel must not be heated again: the oven stays out of service until the glass or door is replaced. The job is to make the area safe, record model, serial and photos for a warranty or safety claim, and order the correct glass pack.

Grease or stains between the oven door glass panes: how to open the door and clean it

Grease and splatter work their way between the panes through the door's vent slots and edges. The only thorough fix is to take the door off and separate the panes; a cloth on a thin stick pushed through the bottom slots gives a partial result without disassembly. The risks are breaking or chipping tempered glass and losing track of screws and spacers.
