Gas burner flame goes out when knob is released, especially on low setting, on a Brandt gas cooktop or range.

Safety first: Work with gas components only if you are competent. Turn off gas supply before removing parts.

Steps:

• Correct lighting procedure: Press and hold the knob for 5–10 seconds after ignition to allow the thermocouple to heat.
• Check flame contact: Ensure the flame directly heats the thermocouple tip. If not, clean the burner and adjust the cap so the flame pattern is correct.
• Inspect thermocouple: Look for kinks, cracks, or loose mounting. The tip should be firmly positioned near the burner.
• Replace thermocouple: If the flame still goes out when you release the knob, replace the thermocouple for that burner. If the problem persists, the gas safety valve may also need replacement by a gas technician.
