[LG gas range] It turns off immediately the knob is released. It won't ignite effectively at once

Troubleshooting

Causes and Symptoms

  • Releasing the ignition knob immediately after it ignites
  • If there is a foreign object on the burner or the burner is assembled incorrectly

If it turns off when the ignition knob is released, it may be related to how the ignition knob was turned, foreign objects on the burner, improper assembly of the burner, and whether or not the battery is discharged.
It turns off if ignition is not detected by the sensor accurately; this is a safety device.

Try this

To ensure correct ignition, turn the ignition knob all the way, press and hold it for 2 to 3 seconds, and release your hand slightly to see if the flame is maintained.
It turns off immediately if you release the ignition knob too quickly after ignition.
If the ignition knob is not turned all the way, the flame will ignite and turn off as soon as you release the knob.

‘Turn it all the way to the 'ignition' position. Hold it for about 3 seconds in the ‘ignition’ position.

Clean the burner cap, burner head and heat sensing rod. Wash the burner cap (black cap) and burner head (silver support) with water and dry them, and rub the heat sensing rod with a dry toothbrush for about 3 minutes to remove any foreign objects. After cleaning, reassemble the burner cap and burner head without tilting, and check if the product ignites normally.

Reassemble the burner cap and burner head without tilting, and check if ignition is normal.

For a product using batteries, replace discharged batteries.
Check if a buzzer sounds once when the knob is turned.
A single buzzer operation is a function that informs you of a dead battery.
(Depending on the remaining battery level, it may or may not ignite after a 'beep’ sound.)
