You turn the oven dial, wait, and nothing lights. What happens next depends on one thing: whether you smell gas. If you do, this is no longer an appliance problem. If you don't, it's usually an ignition fault for an appliance technician, and sometimes a connection problem for a licensed gas professional. Here's how to tell which situation you're in and who handles each part.
I smelled gas near the oven — what now?
Get everyone out of the building now, and call 911 once you're outside. Don't touch the oven controls, flip switches, use a phone indoors, open windows or try the gas shutoff on your way out. Stay outside until the fire department or gas utility says the house is safe.
Do the same for a carbon monoxide alarm, even with no gas smell. Carbon monoxide has no odor, and an alarm can point to a combustion or venting problem anywhere in the house, not only at the range. CPSC's carbon monoxide guidance covers the response to an alarm; test and replace your alarms as their manufacturer directs.
Don't go back in because the smell fades, and don't try the oven again to see whether gas is still flowing. Once responders clear the house, their report or shutoff tag tells you what they found and which professional comes next.
No smell and no alarm: what a failed light can mean
If the oven won't light and there's no gas odor or alarm, turn the dial off, leave the oven unused and book an appliance technician. Don't keep retrying, and don't remove panels to look.
Gas ovens light in different ways. Many use a hot-surface igniter, a glow bar that heats up before the oven's gas valve opens. Others use a spark igniter, and older ranges may have a standing pilot. In many glow-bar ovens the valve opens only when the igniter draws enough current, so a worn igniter can glow and still leave the oven unlit. A click, a glow or silence doesn't identify the failed part on its own. Depending on the model, the cause could be the igniter, the ignition control, the oven's safety valve, wiring or power, or the burner assembly. Finding which one is the technician's job, following the manufacturer's service instructions.
If the oven lights on a later try, the fault is still there. Write down the model number and what happened rather than trying to recreate it for the technician.
Who fixes what
| Part of the problem | Who handles it |
|---|---|
| Igniter, ignition control, oven safety valve, burner, wiring, controls | A qualified appliance technician |
| Gas piping, the appliance shutoff, the connector and the connection | A licensed gas professional; in Massachusetts, that's our part |
| A new circuit, receptacle or panel work | An electrician |
A plumbing visit isn't an oven diagnosis, and an appliance repair doesn't cover fuel piping. If a problem touches both, the written scope should say who does which step.
Can I still use the stovetop?
Ask the technician first. The burners and the oven may use separate parts, but they share one appliance and one gas supply, and a burner that lights doesn't prove the oven fault is isolated. After a gas-odor call, use no part of the range until the responsible professional has evaluated it. If you smell gas at any point, leave and call 911 from outside.
Repair, replace or switch to electric
Whether to repair the oven is the appliance technician's call, based on the model, the confirmed fault, parts availability and the cost of the repair. Age alone doesn't settle it.
If you replace it with another gas range, the connection still needs a look: the new model's input, the connection location, line capacity, an accessible shutoff and an approved connector. Delivery crews generally don't make the gas connection. We do, and new or extended piping goes through our gas line installation service.
Switching to electric isn't a cord swap. We disconnect and cap the gas piping under the permit that applies, and an electrician checks the panel and installs the circuit the new range needs. Each trade prices its own part.
After clearance, when the problem is on the gas side
Sometimes the report points to the supply: the piping, the shutoff, the connector or the connection itself. That's where Jeneral Plumbing comes in. We start with the fire department or utility report and the shutoff status, then review the accessible piping, the shutoff, the connector's condition and routing, and any permit, pressure test or inspection the repair needs. We won't ask you to restart the oven or recreate a smell, and gas service and appliance relighting follow the utility's and manufacturer's requirements. Our gas line repair service explains that sequence.
If responders trace an alarm or odor to a water heater or boiler instead, the cleared follow-up may fit our gas water heater service or boiler repair.
