Wiring Issues: Damaged or loose wiring can interrupt signals between the sensor and the control board, resulting in the error code.
Control Board Malfunction: Occasionally, a defective control board misreads sensor inputs, causing the F3 error.

Symptoms of F3 Error Code

When the F3 error code appears, you may notice:

Temperature inconsistencies during baking or cooking.
Touch controls becoming unresponsive or operating erratically.
Oven failing to reach set temperatures or overheating.

Troubleshooting Steps

To resolve the F3 error code, follow these steps:

Power Cycle the Stove: Turn off the stove, unplug it, and wait for at least five minutes. Plug it back in and check if the error persists.
Inspect the Temperature Sensor: Access the back of the stove and locate the temperature sensor. Ensure it’s securely connected and free from visible damage.
Examine Wiring Connections: Check for frayed wires or loose connections. Tighten any loose connectors.
Test the Control Board: If the error continues, the control board may need replacement. Consult a professional technician for assessment.

When to Seek Professional Help

If troubleshooting doesn’t resolve the issue, contact a certified LG technician. They can ensure proper diagnosis and repairs, preventing further complications.

Common Causes of F3 Error Code

The F3 error code on your LG stove usually indicates a problem with the temperature sensor. Understanding these common causes helps in troubleshooting effectively.

Faulty Temperature Sensor

A faulty temperature sensor often triggers the F3 error code. This component measures the oven’s temperature. If it malfunctions or provides inaccurate readings, your stove may not heat properly. To check the sensor, visually inspect it for damage or wear. If it appears damaged, replacing it is necessary.

Wiring Issues

Wiring issues can also lead to the F3 error code. Damaged or loose connections between the temperature sensor and the control board might cause this error. Inspect the wiring for frays, breaks, or corrosion. Ensure all connections are tight and secure. If any wiring appears faulty, replacing it can resolve the problem.

Control Board Malfunction

A malfunctioning control board can trigger the F3 error code, too. This board interprets signals from the temperature sensor and regulates the oven’s temperature. If there’s an issue, the control board may not communicate correctly with the sensor. If you’ve checked the sensor and wiring without finding a problem, consider testing or replacing the control board.

Troubleshooting LG Stove F3 Error Code

Encountering an F3 error code on your LG stove can be frustrating, but several steps can help you diagnose and resolve the issue.

Initial Steps for Diagnosis

Start by conducting a quick visual inspection. Check for any obvious signs of damage or loose connections at the temperature sensor. Power off the stove and unplug it from the wall. Wait for at least five minutes before plugging it back in. This power cycle can reset the system and clear temporary errors.

Inspect Temperature Sensor
Examine the temperature sensor for any physical damage. Look for cracks or corrosion. The sensor should be securely connected to the wiring harness without any frayed or broken wires.
Check Wiring Connections
Ensure all wiring connections between the temperature sensor and control board are intact. Tighten any loose connections. If you find any damaged wires, consider replacing them.
Test the Temperature Sensor
Use a multimeter to measure the resistance of the temperature sensor. At room temperature, it should read between 1,000 to 1,200 ohms. If the reading falls outside this range, replace the sensor.
Examine the Control Board
Inspect the control board for burnt components or burnt smell. If you notice anything unusual, the control board may need replacement.
Reassemble and Test
After completing these checks and repairs, reassemble everything. Plug the stove back in and power it on. Monitor the stove for the F3 error code. If the error persists, it’s wise to call a certified LG technician for professional assistance.

Taking these steps can help you effectively troubleshoot the F3 error code on your LG stove.

Repair Options for F3 Error Code

You can resolve the F3 error code on your LG stove through DIY repair solutions or by seeking professional help depending on the severity of the problem.

DIY Repair Solutions

Start by power cycling your stove. Unplug it for five minutes to reset the system. After that, check the temperature sensor and its wiring connections.

Inspect the Temperature Sensor: Look for physical damage like burns or cracks. Ensure that the sensor is securely mounted.
Test the Resistance: Use a multimeter to measure the sensor’s resistance. At room temperature, it should read between 1,000 to 1,200 ohms. If it’s outside this range, the sensor likely needs replacement.
Examine Wiring Connections: Check all wiring for loose connections or damage. Make sure the wires are intact and properly connected to the control board.
Inspect the Control Board: Look for burnt spots or corrosion. A malfunctioning control board could prevent the sensor from transmitting accurate data.

After these checks, reassemble your stove and monitor it for the F3 error code. If you don’t see the error again, the issue is likely resolved.

When to Call a Professional

If you’ve gone through the DIY steps and still experience the F3 error code, contacting a certified LG technician is the best course of action.

Signs that a professional is needed:

Persistent Error Code: If the F3 code reappears after your repairs, the problem may require specialized tools and knowledge to diagnose correctly.
Complex Wiring Issues: If you’re uncertain about the wiring connections or find extensive damage, a technician can provide the expertise needed to address these concerns.
Control Board Replacement: If the control board needs replacement, professionals can ensure the new board is installed safely and correctly.
