What F9
actually means.
LG groups several codes around oven heating: F9 means the upper oven is not heating properly, F6 is an upper oven heating error and F19 is an oven heating error. On a gas LG that usually means the igniter or valve; on an electric one, an element or its relay.

What to do when F9 shows on the stoveKind of codeOven heating
The oven part of the stove was set to bake or broil and did not warm the way the controls expected, or took far too long to get there. On an electric stove a bake or broil element that has burned through is the everyday reason; on a gas stove the oven igniter and the valve it opens are looked at first. The wiring and the relay on the board are checked before the board itself is blamed.
Usually leads toStove oven heating repair
The oven part of a stove that stays cold, heats slowly or bakes too hot or too cool, fixed at the bake and broil elements, the oven igniter, the gas valve or the temperature sensor.

Before you book,
in this order.
Each step comes from LG's own guidance for F9 on its stoves. Follow it to the end: the last card says whether this is a visit.
Press CLEAR/OFF and start the bake again.
Take out any foil on the oven floor and make sure the racks and door are closed normally.
If the code comes back, switch the breaker off for 30 seconds and back on.
Book a visit if the oven still will not heat, and if you smell gas, leave and call the gas utility from outside.
Still there?
It usually turns into stove oven heating repair. Book with the code and the model number.
What not to do
F9 is not LG's sensor code. The sensor has its own numbers, F1 and F2; F9 says the heat itself did not come.
