None Gas Cooktop: not extinguishing
What is this symptom?
If your gas cooktop burner flame remains lit even after turning off the control knob, it indicates that gas flow is not stopping. This can pose a serious safety risk. Common causes include a stuck gas control valve or a malfunctioning safety shutoff mechanism. Immediate attention is required to prevent potential hazards.
Possible Causes
Stuck or defective gas control valve / knob assembly
How to Identify: Knob feels loose, too easy to turn, or does not click into the off position; gas continues to flow after knob off.
Part: Gas control valve / burner knob assembly
Internal valve mechanism failure (thermocouple/safety shutoff failure)
How to Identify: Flame persists regardless of control knob position; safety mechanisms not shutting gas flow.
Part: Safety shutoff valve / thermocouple
Gas supply regulator or external malfunctions
How to Identify: Gas continues to flow after knob off; unrelated to cooktop internal components (e.g., regulator stuck open.
Part: Gas supply regulator / line
