Burner goes out when you release the knob
What you see
On full-safety models the flame holds only while the knob is pressed. Holding it a few seconds after lighting is normal.
Likely causes
The thermocouple, a heat sensor that holds the magnetic gas valve open, is dirty, out of the flame or failed, or the valve is weak.
Safe to try
Wipe the thermocouple tip dry, seat the burner cap and hold the knob 5–10 seconds. Never tie it down.
Technician
Tests the thermocouple and valve, and fits a matching part.
