A gas odor near your stove means natural gas may be escaping, and it should never be ignored. The smell is a deliberately added scent, often described as rotten eggs or sulfur, that warns you of a possible leak. If you smell gas near your stove in San Mateo, your safety comes first; SanMateo FixHub can help diagnose the stove itself once the situation is confirmed safe.
A brief, faint whiff of gas as a burner lights is common and usually clears quickly. What warrants concern is an odor that lingers, grows stronger, or appears when no burner is on. In those cases, follow the safety steps below before anything else.
Safety First
- Stop using the stove immediately and turn off all burner knobs if you can do so safely.
- Do NOT operate light switches, appliances, or anything electrical, and do not use any flame, lighter, or match.
- Do not use your phone while inside the area where you smell gas.
- If the smell is strong, leave the area right away and take others with you, leaving a door open as you go.
- From a safe location away from the odor, call PG&E's gas emergency line at 1-800-743-5000, or call 911.
- Do not turn the gas or appliances back on yourself; wait for the utility or a qualified professional to confirm it is safe.
- Once the leak source is confirmed and the area is safe, contact a qualified stove technician such as SanMateo FixHub for any needed stove repair.
Likely Causes
These are common possibilities — an on-site check is the only way to confirm what's happening with your stove.
A burner left slightly open
A knob turned partway on, or bumped without igniting, can release unburned gas. This is one of the most common and easily overlooked sources of odor.
Slow-lighting burner
A burner that takes several seconds to catch releases a small amount of gas before ignition, which can produce a brief smell each time.
Worn burner valve or seal
A valve or seal that no longer closes fully can allow a small, steady release of gas even when the burner is off.
Loose gas connection
A fitting or connection behind or beneath the stove that has loosened over time can let gas escape and needs professional inspection.
Incomplete combustion
A burner producing a weak or yellow flame may not be burning gas fully, which can create odor and warrants a closer look at the burner.
What Should You Do Next?
- 1Treat safety first: follow the steps above before troubleshooting anything.
- 2Check that all knobs are fully in the off position once it is safe to do so.
- 3Note when the smell occurs, such as only while lighting a burner or constantly.
- 4After the utility confirms the area is safe, contact SanMateo FixHub to inspect the stove.
