If you own an LG double oven, you may have encountered the F19 error code, which can be frustrating when it interrupts your cooking plans. This specific code indicates that your oven is failing to reach the minimum required temperature within a set timeframe, often due to ignition problems. In this guide, we’ll break down what causes this error, how you can troubleshoot it yourself, and ways to prevent it in the future.

What Does the F19 Error Code Mean?

The F19 error code is a safety feature built into LG ovens to alert you that the heating system isn’t working correctly. When this error occurs:

• The oven fails to heat to the desired temperature within a certain period.
• Cooking times may be inaccurate, or the oven may not ignite at all.
• For double ovens, the code could be triggered by issues in either the upper or lower oven, so both ignitors may need inspection.

Essentially, the F19 code points to a problem with the ignitor or the burner assembly, which are critical components for starting and maintaining the oven flame.

Common Causes of the F19 Error

Several factors can trigger the F19 code in LG ovens. The most common include:

• Worn or faulty ignitor – Ignitors degrade over time and may fail to produce sufficient heat to ignite the gas.
• Loose or damaged wiring – Electrical connections to the ignitor or burner can become loose or corroded.
• Burner issues – Blockages, dirt, or misalignment in the burner assembly can prevent ignition.
• Mechanical wear – Screws, panels, or brackets that secure the ignitor may strip or loosen, affecting performance.

In most cases, replacing the ignitor resolves the issue completely, especially if the old one shows visible wear.

How to Fix the F19 Error Yourself

If you feel comfortable with basic appliance repairs, you can attempt a DIY fix. Here’s a step-by-step overview:

1. Turn off the oven and unplug it – Safety is the first priority.
2. Access the ignitor – For the lower oven, remove the bottom metal panel by unscrewing two black screws. Slide out the panel to reveal the silver sheet metal covering the burner.
3. Remove the burner assembly – Unscrew the sheet metal panel to access the burner and ignitor. Carefully disconnect the old ignitor.
4. Install the new ignitor – Fasten it securely to the burner assembly, making sure all screws are tight.
5. Reassemble – Return all panels and screws in the reverse order of disassembly.
6. Test the oven – Power it on. The new ignitor should glow orange, and the oven should ignite within seconds.

Tips for a smooth replacement:

• Keep extra screws or nuts handy in case some threads are stripped.
• Use a Phillips screwdriver and a hacksaw if a screw needs trimming.
• Inspect the burner assembly for dirt or corrosion while it’s exposed.

Preventative Measures to Avoid the F19 Error

After successfully fixing the F19 error, you can take steps to reduce the risk of future issues:

• Regularly clean the burner area – Dust, grease, and food particles can accumulate and block ignition.
• Inspect ignitors periodically – Replace them before they fail completely if they appear brittle or cracked.
• Check wiring connections – Ensure all electrical contacts remain secure and free of corrosion.
• Avoid physical damage – Be careful when cleaning or moving the oven panels to prevent stripped screws or bent components.

Following these simple maintenance steps can help your LG oven run reliably and extend the lifespan of the ignitor and other critical parts.

Final Thoughts

The LG F19 error code is a common but fixable problem, usually linked to the ignitor or burner assembly. With careful inspection, proper replacement, and routine maintenance, you can restore your oven to full functionality. For complex or recurring issues, professional service is recommended, but many homeowners find this repair manageable with basic tools and safety precautions.
