A gas stove burner that won't turn off with the knob is a safety emergency. Act immediately.
Immediate Steps
- Turn off the gas supply valve behind or under the stove — it's a small valve on the gas supply line
- If you can't find or reach the valve, turn off gas at the main shutoff (typically near the gas meter)
- Ventilate the room
- Do not use the stove until repaired
- Call a technician — do not attempt to repair gas valve components yourself
What Causes a Burner to Stay On
Stuck gas valve: The internal gas valve that the control knob operates can stick in the open position. This is typically caused by corrosion or debris inside the valve. The knob turns but doesn't close the gas flow. Requires valve replacement — not a DIY repair.
Control knob damage: Rarely, the knob mechanism itself breaks in a way that holds the valve open. Less dangerous than a stuck valve — the gas supply can be closed separately.
Valve stem debris: Food spills that work their way into the knob housing can jam the valve stem. This can sometimes be freed by a technician without full valve replacement.
Repair Cost
Gas valve replacement on residential ranges: $150–300 depending on brand and access difficulty. This requires a licensed gas appliance technician in Texas.
Do Not
- •Do not attempt to disassemble the gas valve yourself
- •Do not leave the stove unattended while troubleshooting
- •Do not use the burner while it's malfunctioning

Stove Burner Not Turning Off in Houston: Safety Guide and Repair
A stove burner that will not turn off — whether it is a gas burner that stays lit or an electric burner that remains hot — is a safety emergency that should be addressed immediately. In Houston, where natural gas cooking is standard in most homes, a gas burner that will not extinguish is particularly serious. Here is what to do and what causes this problem.
Immediate Steps: Gas Burner Won't Turn Off
If a gas burner will not turn off when you rotate the knob to the off position, take these steps immediately: (1) Turn the knob past the off position to see if the valve closes at a slightly different position — sometimes the valve seat is worn and the "off" detent does not fully close the gas flow. (2) If the burner cannot be controlled by the knob, locate the gas shut-off valve behind the range (usually a ball valve with a lever handle) and turn it perpendicular to the gas line to shut off supply to the range. (3) If you cannot access the range shut-off valve, use the main gas supply shut-off for your home. (4) Call for service before using the range again.
Causes of a Gas Burner That Won't Shut Off
The most common cause is a failed gas valve or valve stem — the valve that controls gas flow for a specific burner wears out and will not fully close. This is a gas appliance repair that requires a certified technician. The second common cause is a debris-packed valve stem where food or grease has entered the valve mechanism and is physically preventing full closure. We disassemble and clean valve stems on range service calls before recommending valve replacement.
Electric Burner Won't Turn Off
On electric ranges, a burner that stays energized when set to off is caused by a failed infinite switch (the control switch behind the burner knob) with a fused or stuck contact. Unplug the range immediately and call for service. Infinite switch replacement costs $20 to $60 for the part.
