Gas cooktop burner flame yellow, lopsided or noisy (inspection and cleaning only)

A normal burner flame is mostly blue, with small yellow tips allowed (more common on propane). A single bad burner is almost always a cap that is not seated, clogged or wet ports, or a mismatched cap and head. All burners yellow or abnormal points to the gas side (wrong orifices for the gas type, a poor conversion, supply pressure), and that goes to a licensed gas technician. The tech's work here is visual inspection, cleaning, drying and reseating only.

Before you start

If you smell gas: do not light anything or operate switches; shut the range off, ventilate, get people out and call the gas utility or 911 from outside
Do not adjust air shutters, orifices, the pressure regulator or the gas valve, and do not convert the range between natural gas and LP; those are licensed gas-tech jobs
Turn burners off and let the grates, caps and heads cool before handling them
Keep water out of the burner base and the orifice; dry everything before relighting

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.
