What F19 means

On LG electric and gas ranges with a numeric F-code display, F19 is listed as an oven heating error. The control expects the oven to heat when it is told to, and F19 means that is not happening as it should. The oven may be slow to warm, may not warm, or may stop and show the code. The list gives the label only, so electric and gas models can have different causes behind it.

Common causes of F19

On electric models: a bake or broil element not heating
On gas models: ignition or burner not lighting
A temperature sensor reading that does not match
A control that is not switching the heat on

✓ One safe check you can try

1. If you ever smell gas, leave the house and call the gas utility from outside. 2. Press CLEAR/OFF, then switch the circuit breaker off for 30 seconds and back on. 3. Try one short bake. If F19 shows again, stop using the oven.

! Why to stop there

Electric and gas ovens heat very differently, so we start by identifying which one you have and which heat path failed.
The code does not say whether a sensor or a heat part is the cause, so we test both before any part is replaced.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F19F19 questions

What does F19 mean?

The oven is not heating the way the control expects. It could be an element, an igniter, or a reading problem, depending on the range. That points to the heating path and not to the keypad.

Why does my oven preheat slowly?

A slow warm-up can come with F19. The control is not seeing the right temperature rise, and the heat path needs testing. Gas ranges use an igniter and burner instead of an element.

Is it safe to keep trying?

On a gas range, stop if you smell gas. Otherwise one trial is fine, but repeated attempts do not help. Let the oven cool fully between attempts.
