What Does f19 Mean on LG Oven? How to Troubleshoot f19 Error?

LG ovens are pretty popular worldwide. These ovens have two parts: a lower oven and an upper oven, to make sure these ovens are functioning perfectly. There are several error codes to let you know if something is wrong. Error code f19 informs about the temperature that it did not go up to 150 degrees Fahrenheit in 5 minutes while the door was closed. It could be due to a faulty oven relay board, faulty oven sensor, or any other heating issues. 

In my own experience, I discovered that tackling this problem might involve replacing the ignitor, a vital component in your oven’s heating system. So let’s dive into the article to understand it better.

Troubleshooting the F19 Error Code on Your LG Oven

The F19 error code on your LG oven indicates that the oven has failed to reach the desired temperature This issue can stem from various factors, including problems with the igniter, relay board, temperature sensor, heating element, gas line, or gas valve. Here’s a step-by-step guide on how to address this error code:

1. Unplug and Reset:

• Start by unplugging your oven from the power source for 3-5 minutes. This step may help reset the oven’s control board and clear the error code. Once the time has passed, plug the oven back in.

2. Check the Igniter:

• If the igniter is not glowing red when the oven is turned on, it’s a sign that it may be faulty and needs replacement. Igniters are typically found near the burner assembly.

3. Inspect the Temperature Sensor:

• The temperature sensor is vital for maintaining the correct cooking temperature. If it’s malfunctioning, the oven won’t heat properly. Check the sensor for any visible damage or loose connections. It’s often located at the back of the oven’s interior.

4. Examine the Heating Element:

• A short-circuited heating element can impede your oven’s performance. Look for visible damage or signs of short-circuiting. If necessary, the heating element will need to be replaced.

5. Verify the Gas Line:

• Make sure the gas line is not clogged or obstructed. A blocked gas line can prevent the oven from heating properly. If you suspect a blockage, contact a qualified technician to clean it.

6. Check the Gas Valve:

• The gas valve is responsible for regulating the flow of gas to the oven. If it’s not opening properly, it can lead to heating issues. Inspect the gas valve for any visible problems, and if needed, have it repaired or replaced by a professional.

Double Oven Consideration

If you have a double oven and are experiencing errors in both ovens, keep in mind that there are two igniters. One is located at the bottom, below the metal panel, and the other at the top, above the metal panel. It’s important to identify which igniter needs replacement if you’re encountering errors in only one oven.

Igniter Replacement (for the lower oven, as an example)

• To replace the igniter, first remove the blue metal panel held in place with two black screws. Slide the panel out. You’ll then encounter a silver-colored sheet metal panel, which needs to be removed using several sheet metal screws.
• After removing the panels, you’ll reach the burner assembly where the igniter is attached. Unplug the old igniter and securely attach the new one.
• Reassemble all the parts in reverse order, making sure to tighten the screws.
• Turn on the oven, and you should see the orange glow from the igniter. The oven should ignite and begin heating up in less than 30 seconds.

Safety Note: It’s crucial to emphasize that you should not attempt these repairs unless you are a qualified technician. Repairing an oven involves a risk of electric shock and gas leaks if not done properly. If you’ve tried these troubleshooting steps and the F19 error code persists, it’s best to contact a professional LG oven repair technician.

By following these steps, you can effectively troubleshoot and address the F19 error code on your LG oven, ensuring it continues to serve you perfectly cooked meals.

Different Types of Error Codes in an LG Oven | f19, f1, f4, and More

F1, F2/F4, F3, F4/F10, F5, F6/F8, F6, F7/F9/F11/F19 are the main error code on every LG oven model. However, it can mean a little bit differently in different models. Code F1 means the stuck button or the temperature sensor is on. F2/F4 refers to the temperature sensor being short-circuited; in contrast, F3 refers to the touch button being short-circuited.

Furthermore, F4/F10 indicates the door lock malfunction, while F5 pops up for the control board failure. F6/F8 sends messages about the main power problem and, in some cases, while the oven is overheating. F7/F9/F11/F19 refers to oven heating issues, and it may not be heating up properly. 

F7/F9/F11/F19 Error Code

This number covers a wide variety of heating issues, making it difficult to determine what is producing it. Despite the door being closed for five minutes, the temperature did not increase to 150 degrees Fahrenheit. Or it could be caused by a faulty oven relay board, a faulty oven sensor, or any other heating issue. Before attempting to repair the oven, make sure you restart it because this error code is sometimes all that is required. 

To begin testing the oven detector, Cut the power and detach the sensor. Then perform an Ohms test; an effective sensor should have around 1,080 Ohms while at room temperature. If it is significantly higher or lower, the sensor must be replaced.

F1 Error Code

This code indicates a problem with a jammed switch on a control center or touchpad. It could also indicate a faulty connection between the oven’s touchpad and the control board. There is no easy way out of this. You can, however, try disconnecting the touchpad ribbon connection from the mainboard and cleaning it with an eraser. If that doesn’t work, get a replacement.

F2/F4 Error Code

An F2 error refers to the oven’s temperature sensor being broken or short-circuited. So, the Lg oven will not function effectively, and you will require the services of a technician to inspect the problem. The component may need a replacement or need to be repaired.

F3 Error Code

F3 indicates that a wire connected to the touch button is short-circuited. This problem could be caused by the control center buttons or wiring. If the problem persists after restarting your oven, you will have to call a repair service.

F4/F10 Error Code

This message means that the oven lock system is not working as it should be. You have the option of replacing the item yourself or hiring a specialist. When you want to start replacing it, make sure the oven is turned off.
Now, unscrew the rear panel and photograph the cabling on your smartphone; you may use it as a guideline to reconnect them correctly after you’re through. Then unplug all of the cables that are connected to the locking mechanism motor. It should be simple to remove the old door lock and replace it from there. If you don’t reconnect the cables correctly, you’ll have further issues with the oven.

F5 Error Code

It indicates an oven relay board problem. You should reset the oven by disconnecting it or removing power from it. Stay at least 40 seconds, then turn it back on.

F6/F8 Error Code

Code F6/F8 indicates that the circuit panel is not receiving enough power or is defective. You can tell which one it is by disconnecting the oven and waiting 10 minutes before turning it back on. Inspect the double breaker and ensure that both breakers are turned on; none are tripped. However, if the code displays again, it implies that the circuit panel has to be repaired or replaced.

How can I gain access to my LG stove?

The oven uses a temperature sensor to determine when it is cooled enough to open the door. If this sensor fails, the lock can become stuck indefinitely. The oven can be unlocked by resetting the sensor. To do this, turn off the oven and wait 5 minutes without reactivating it.

If it doesn’t help, start a fresh self-cleaning cycle and then terminate it after a few minutes. If the oven displays an error code, do not try to begin a new self-cleaning cycle. You can reach its door’s locking mechanism via the back access panel to manually release it. It will unlock the door and allow you to look inside the oven for further repairs.
