List Of Common LG Oven Error Codes


Do you experience issues with your LG oven? The fact that modern ovens are far more feature-rich than older models means that more things can go wrong with them.

We created this tutorial to assist you since we know that no one wants to spend all day attempting to fix an oven.

LG provides support on their page if you require additional assistance. The fault codes there for each specific model are not, however, listed.

You can look in the LG oven owner’s manuals to discover that information.

Steps to Take

If you don’t know what’s wrong with your LG oven and you want to figure out what it is, these are the first steps you should take.

Always start by looking at how the oven is set. We can sometimes set the temperature or timer to the wrong setting by mistake.

This would make it look like the oven is stuck in the preheating stage for a long time.

While you’re there, make sure the oven door is all the way shut. This could make your oven make a noise or never heat up all the way.

If neither of these easy fixes solves the problem, you’ll need to look for an error code on the oven.

These are codes that tell you what’s wrong and show you how to fix it.

If you still have your owner’s instructions, it will help you in this situation.

But we have a list of LG oven error numbers here for you. They may be different depending on the type, so keep that in mind as you try to figure out what’s wrong with your oven.


How to Understand LG Oven Error Codes

Error numbers are made up of the letter “F” and a number. In some types, the oven will also make a beeping sound or flash an error code.

If you can’t turn off the oven, this can be annoying, so you might want to unplug it.

You will need to clear the error code before you try to fix the oven. Before you try to use the oven again, press “CLEAR/OFF” first.

If the error code comes up again, turn off the circuit breaker that the oven is using and wait at least 30 seconds before turning it back on.

If the error code comes on again, you’ll probably need a professional to fix your oven.

You can do the repairs yourself if you feel fine doing so.

This will save you money because you will only have to pay for the new part and not have to hire a repair person.

Before you open the back panel, you should always make sure the oven is unplugged. You should also have someone help you move the oven, since they can be heavy.

Putting the oven on a piece of cardboard can also keep damage from happening to your kitchen floor.

Please remember that some error codes can mean different things for different LG models depending on when they were made.

We know that the different meanings of the error codes could be confusing, but if you don’t know what to do next, you can leave a message and ask us.


Error Code F1: Button Stuck

Temperature sensor is open (for model # LSE4613ST) (error code F1)

If you see this code, it means that a button on the control panel or mouse is probably stuck.

It could also mean that the link between the oven’s control board and the touchpad is broken.

No service calls to your house. There are no plans.

There is no easy answer to that. But you can try taking the touchpad ribbon wire off the control board and using an eraser to clean it.

If that doesn’t work, you should get a new keyboard.

Another meaning of the F1 error number is that a temperature sensor or thermistor is open, so the control board can’t get any information from it.


Error Code F2/F4: Shorted Temp Sensor

If you get an F2 error, it could mean that the oven’s temperature monitor is broken or that there is a short in the wiring.

This means that it won’t work right anymore, and you’ll need a professional to check it for you. It could be that the part needs to be fixed or changed.


Error Code F3: Touch Button Shorted

F3 means that a short circuit has happened in a wire that goes to a touch button. The problem could be with the buttons or wires on the control panel.

If it still shows up after you restart the oven, you will need to call a repair service for help.


Error code F4/F10 means that the door lock didn’t work.

This mistake means that the lock on the oven door is broken. You can try to replace the part on your own or call a technician.

Make sure the oven is stopped before you try to change it.

Next, take off the back of your phone and take a picture of the wires. This will help you put them back on the right way when you’re done.

Then you can unplug all the wires that go to the motor that opens the door.

From there, taking off the old lock and putting on the new one should be easy.

Make sure you connect the wires properly or the oven will give you more trouble.


Error code F5: The relay on the control board broke.

This means there was a problem with the switch board in the oven. You will need to unplug the oven or cut the power to it in some other way so that you can turn it back on. Wait at least 30 seconds before turning it on again.


Error Code F6/F8: Problem with Main Power
Error code F6 means that the oven is too hot (for model number LSE4613ST).

This means that the computer board is either broken or not getting enough power.

You can find out which one it is by stopping the oven and waiting 10 minutes before turning it back on.

Also, check the double switch to make sure that both breakers are on and none of them are tripped.

But if the code comes back, it means the board needs to be fixed or replaced.


Error Code F7/F9/F11: Oven Doesn’t Get Hot

This code covers a wide range of heating problems, which can make it hard to figure out what is wrong.

It means that with the door closed, the oven temperature did not rise above 150°F in 5 minutes.

It could be because the oven circuit board is broken, the oven sensor is broken, or there are other heating problems.

Make sure to turn the oven back on before you try to fix it. Sometimes that is all it takes.

To test the oven sensor, first turn the oven off and take the sensor out.

Then do an Ohms test. At room temperature, a good gauge will have about 1,080 Ohms. If it’s a lot higher or lower than normal, you’ll need to change the monitor.

Another problem could be that the oven’s relay board is broken. This happens when the relay contacts get dirty and stop giving continuity, which means that the broil or bake elements don’t get power.


Child Lock is another common oven code.

When “Child Lock” is shown on the control screen of your oven, you can’t use it.

If you have young children at home, you can use this safety function.

This is not an error code, but it can be confusing if it was turned on by accident.

To turn off the child lock, press and hold the “Oven Lock” button for three seconds.

This should get rid of the lock so you can use your oven’s control panel again.

If the “Child Lock” message doesn’t go away and you can’t turn your oven back on, you should call a repair service.

Make sure to turn off the oven as soon as you can, especially if food is stuck inside.



This is another code that will lock the control panel even though it is not a mistake.

This means that the self-cleaning mode is on and that you can’t use the oven until it’s done.

If you can’t get rid of the code, it means that your unit is broken and needs to be fixed.


Error Codes HS

When “HS” is shown, it means that there is a “hot surface” on the stovetop. It will stay on until the surface has cooled off.

Press the “CLEAR/OFF” button to clear this code by hand.


Error Code : PF

“PF” means that your oven lost power. You can clear the display by pressing the “CLEAR/OFF” button. This code is meant to let you know that the oven lost power at some point, which usually happens when there is a blackout in your area.


Error Code SB

This code means “Sabbath Mode” and is generally used on the Jewish Sabbath and Jewish holidays.

When this mode is on, the oven won’t turn off until this mode is turned off. The “CLEAR/OFF” button is the only one that doesn’t work on the control panel.

To get out of this setting, just hold down the “SETTING” button for three seconds. This should put you back in charge of how the oven is set.



These are all of the most common error numbers that your LG oven might show.

Remember that if the unit is giving you trouble, you should always start by restarting it. Most of the time, this is enough to fix any problems the oven was having.

But if the error code comes back, you’ll have to take more steps to fix it.

Using your oven’s owner’s manual can help you figure out what’s wrong. You just have to find the code in the directions.

If you think you can fix the oven yourself, always stop it before you start.

If you just cooked on it, wait at least an hour before touching it.

A professional can help you fix things if you can’t figure out what’s wrong.

Some models have error numbers that aren’t on this list. If you’re not sure what to do, check the owner’s instructions. LG has a list of them on its website, so if you’ve lost yours, you can download a copy to use as a guide.
