LG ovens are known for their reliability and precise cooking performance, but even the best appliances can sometimes display error codes. One common issue is the F2 error code, which indicates a problem with the oven’s temperature sensor. This sensor monitors and regulates the oven’s internal temperature, ensuring your dishes cook evenly. When it malfunctions, the oven may fail to reach the correct temperature, overheat, or display inaccurate readings.

What the F2 Error Means

The F2 code is triggered when the oven detects that the temperature sensor is not providing accurate feedback. Without correct temperature readings, the oven cannot maintain precise cooking, which can affect everything from baked goods to roasted meals. Symptoms of an F2 error may include:

• Oven stops heating or fails to maintain temperature.
• Display shows F2 error code repeatedly.
• Cooking times are inconsistent, or the oven overheats.

Common Causes of F2

Several issues can trigger this error:

• Faulty Temperature Sensor: Over time, the sensor can fail due to age or internal damage.
• Loose or Damaged Wiring: Wires connecting the sensor to the control board may become frayed, detached, or corroded.
• Control Board Glitch: In rare cases, the oven’s main control board may misinterpret sensor signals, leading to an F2 code.
• Improper Sensor Placement: If the sensor is knocked out of position or not secured properly, it may send inaccurate readings.

DIY Solutions to Fix F2

If your LG oven shows the F2 code, you can attempt these steps to resolve it before calling a technician.

Step 1: Reset the Oven

• Turn off power at the circuit breaker or unplug the oven.
• Wait for a few minutes to let the control board reset.
• Restore power and see if the error persists.

Step 2: Inspect the Temperature Sensor

• Locate the sensor at the back of the oven, usually secured with screws.
• Remove the back panel carefully to access the sensor and wiring.
• Check for any visible damage, such as frayed wires, loose connectors, or corrosion.
• If any issues are found, repair the connection or prepare for sensor replacement.

Step 3: Replace the Sensor

• If the sensor is faulty or damaged, obtain a replacement from LG or a trusted appliance parts supplier.
• Remove the old sensor, install the new one, and reconnect the wiring securely.
• Test the oven to ensure it reaches and maintains the correct temperature without displaying F2.

Replacing a faulty sensor usually resolves the issue quickly and restores accurate temperature control.

Preventive Measures

Preventing future F2 errors is mostly about proper maintenance and careful handling:

• Avoid hitting or pressing against the sensor when loading racks or cleaning the oven.
• Periodically inspect the wiring and sensor connections for wear or damage.
• Keep the oven interior clean to prevent residue from affecting sensor readings.
• Avoid DIY electrical modifications that could disturb sensor wiring.

Quick Troubleshooting Checklist

• Reset the oven by cutting power for a few minutes.
• Inspect the temperature sensor for damage or loose wiring.
• Replace the sensor if readings are inconsistent or it appears defective.
• Ensure proper installation and secure connections for the new sensor.

LG ovens rely on the temperature sensor to maintain precise cooking conditions. Addressing an F2 error promptly ensures your oven works reliably, providing perfect results for every meal.
