Gas Cooktop Woes: Ignition Woes and Flame Extinction

The heart of any kitchen is undoubtedly the cooktop, and when it comes to gas cooktops, a seamless ignition and steady flame are key. However, if you find that pressing the knob lights the fire only to see it extinguish when you let go, frustration sets in. In this guide, we'll explore the potential causes behind this issue and provide practical steps to troubleshoot. Additionally, we'll discuss the importance of proper pressing time and the role of the thermocouple in ensuring safety.

Quick Fixes for Gas Cooktop Ignition Woes

1. Press and Hold:

  • Sometimes, a brief press might not provide enough time for the electromagnetic valve to open fully. After igniting, continue to hold the knob for at least 5 seconds before releasing. This ensures sufficient time for the valve to allow a steady flow of gas.

2. Dirty Thermocouple:

  • The thermocouple, or flame failure safety device, is a critical safety feature. If it's dirty, it might not function correctly. Clean the head of the thermocouple carefully using a soft brush or compressed air. This can enhance its performance and reliability.

3. Extended Press for Safety:

  • To prevent flame extinction due to a premature release of the knob, it's advisable to extend the pressing time. Hold the knob for at least 5 seconds after ignition before letting go. This ensures that the flame is stable before the safety device allows the gas flow to continue.

When to Seek Professional Help:

If the issue persists despite the above measures, there might be underlying problems with the thermocouple or the electromagnetic valve. In such cases:

  • Contact the Manufacturer:

    • Reach out to the manufacturer's customer support. They can provide guidance, troubleshoot the issue remotely, or advise on the next steps.
  • Professional Inspection:

    • If the thermocouple or electromagnetic valve is suspected to be damaged, it's crucial to seek professional assistance. A certified technician can diagnose the problem accurately and perform any necessary repairs or replacements.


A gas cooktop that momentarily ignites but extinguishes upon release can be perplexing, but with the right approach, it's a challenge that can be overcome. Always prioritize safety by following recommended pressing times and cleaning the thermocouple regularly. If issues persist, don't hesitate to contact the manufacturer or a qualified technician for a thorough inspection and resolution. A well-maintained gas cooktop ensures not only convenience but also safety in your kitchen.
