Answer to continue safely
Is it safe to keep using?
No. Never use a gas appliance when a gas odor is present. This is a life-safety situation. The rangetop must not be used until a licensed professional has inspected and cleared all gas connections and internal valves.
Can I reset the code?
No. A gas leak cannot be resolved through a reset. Physical inspection and repair of the leak source by a licensed professional is required before the rangetop can be used safely.
When to stop immediately?
Stop if you notice: Stop using the rangetop immediately if you smell gas at any time during operation., Do not relight any burner if you smell gas after a flame-out — ventilate first..
Symptoms You May Notice
Sulfur or rotten egg odor near the rangetop
Natural gas and LP are odorized with mercaptan — a compound that smells like sulfur or rotten eggs — specifically so leaks can be detected. Any such odor near the HRTP rangetop is a potential gas leak requiring immediate response.
Odor persists after all burners are confirmed off
If the gas smell remains after all knobs are visually confirmed in the off position, gas may be leaking from a supply connection, valve, or internal fitting rather than from the burners themselves.
Faint gas smell when burner knob is near off position
A small amount of gas odor is normal when a burner knob is turned to ignite — but odor that persists for more than a few seconds after the knob reaches the off position indicates a valve that is not fully sealing.
Hissing sound from under the rangetop or gas line connection
An audible hiss from the gas supply line, shutoff valve, or from beneath the rangetop suggests gas is escaping under pressure from a fitting, connection, or valve.
Possible Causes
Loose or degraded supply line connection
The flexible gas supply line connecting the rangetop to the wall shutoff can develop leaks at the fittings over time, especially if the rangetop has been moved for cleaning or installation.
Requires ProfessionalBurner valve not sealing fully
A burner control valve that is worn, damaged, or contaminated with grease may not fully close when the knob is in the off position, allowing a small amount of gas to pass.
Requires ProfessionalInternal gas fitting or manifold leak
Connections inside the rangetop body — at the manifold, orifice holders, or burner valve fittings — can develop leaks from vibration, corrosion, or improper installation.
Requires ProfessionalSafe Checks You Can Do
-
1
Evacuate and ventilate immediately
If you smell gas, do not operate any electrical switches, lights, or appliances. Open windows and doors to ventilate. Evacuate the kitchen and the home if the smell is strong. Call 911 or your gas utility emergency line from outside the building.
Do not attempt to locate the leak yourself — gas in air concentrations between 5-15% can ignite from a single spark.
-
2
Shut off the gas supply if safe to do so
If the smell is faint and localized, and you can safely reach the rangetop's wall shutoff valve without operating any switches, turn the shutoff valve to the closed position (perpendicular to the pipe). Do not turn the valve if doing so requires passing through a gas-concentrated area.
The shutoff valve is typically located behind or beside the rangetop on the gas supply line.
-
3
Do not use the rangetop until cleared by a professional
Have a licensed gas plumber or Dacor-authorized technician inspect all supply connections, fittings, and internal valves before using the rangetop again. Do not attempt to locate or repair a gas leak yourself.
A licensed technician will use a gas leak detector to locate even very small leaks that are not detectable by smell alone.
When to Call a Professional
Contact a qualified technician if:
- Any confirmed gas leak requires immediate licensed gas technician or plumber repair — this is not a DIY repair.
- Internal valve or manifold leak requires a Dacor-authorized technician with proper gas service certification.
- Gas utility emergency line (1-800 number on your bill) should be called if the odor is strong or spreading.
