Error Codes

Oven Not Heating

Are you facing LG oven not heating problem? Here are the few things you have to do.


You have to inspect whether the LG oven ignitor is working in fine condition or not. If the ignitor gets red lights for about 30 to 60 seconds, consider that the light is reflected inside your oven cavity. You have to look at the ignitor when the oven is ON as the unit doesn't heat if the ignitor is not running. If it glows for more than 1.5 minutes without igniting the gas flame, it indicates the failure of the ignitor. So, you need to replace the defective ignitor.

Bake Element

You have to remember that the baking element glows if it heats properly. When this baking element is not glowing as red, you need to check for holes or blisters to see if the element is burned. If there are no damage signs, test it with a multimeter for continuity. It needs to be replaced if it has no continuity.

Spark Electrode

The spark electrode is used in the oven to ignite the gas on the burner. If it does not have a spark, then your gas doesn't ignite. So, check the spark electrode to ensure that there are no defectives or cracks to the tip in the porcelain housing. Make sure to replace it if the electrode is damaged.

Oven Temperature Not Accurate

If you feel food is not baking evenly, check some causes below.

Ignitor draws current through the gas safety valve to open it. Overtime usage, the ignitor weakens that results in it will take more time to open the gas valve.  Consequently, the oven temperature can drop too low before the burner reignites resulting in your oven temperature might be accurate.

Check the temperature sensor as it works with the control board of the oven to regulate the temperature. If your LG oven is not maintaining the correct temperature, you can recalibrate it up to 35 degrees F. You will need to refer to the guidelines on how to calibrate your oven in the owner's manual.

Stove Burner Won't Light

Spark electrode - When the spark electrode is worn out or defective, it may be too weak to ignite the gas. If it got damaged, it will make a click sound when the burner is turned on, but the burner is won't light. If you observe this situation, it is signed as defective. So, replace the spark electrode.

Ensure that the spark wire is not loose or disconnected. It prevents the spark electrode from igniting the gas effectively. You have to replace the spark wire if it is burned or broken.
