Why Does My Gas Oven Smell Like Gas When I Turn It On?

What to do first: stop using the oven

If you smell gas near your oven, the first and most important step is to stop using it and call a licensed technician. This isn't a repair to troubleshoot yourself or wait on — a persistent gas smell means something in the gas delivery or ignition system isn't sealing or combusting properly, and that needs a professional inspection before the oven is used again.

Common causes of a gas smell

A brief smell right when the oven ignites is sometimes normal, since a small amount of gas releases in the moment before the igniter lights it. But a smell that lingers, that happens every time you use the oven, or that's noticeable even when the oven is off, usually points to something that needs attention — a burner that isn't igniting quickly enough (letting gas build up before lighting), a valve that isn't sealing fully, or a connection issue.

What a licensed technician checks

• Igniter timing and how quickly it lights the burner
• Gas valve seal and function
• Burner condition and flame color (blue vs. yellow)
• Gas line connections at the oven
