Is your gas LG range showing an F6 error code? Don’t worry — you can likely resolve this issue yourself with some guidance. Here’s a straightforward guide to help you fix it.
What Does the F6 Error Code Mean?
The F6 error code indicates that the oven’s temperature has exceeded 650°F for more than two minutes during baking or broiling. This does not apply to self-cleaning cycles, which are designed to reach higher temperatures.
This code is a safety measure, signaling a potential issue with the oven’s temperature sensor. Consistently high temperatures can pose safety risks and may damage internal components.
Common Causes of the F6 Error Code
Understanding the possible reasons behind the F6 error can help you identify the root of the problem more effectively. Here are the most common causes:
- Faulty Temperature Sensor (RTD): The temperature sensor, also known as the Resistance Temperature Detector (RTD), monitors the oven’s heat levels. If it malfunctions, it may send inaccurate readings to the control board, triggering the F6 error.
- Damaged Wiring or Connections: Loose, frayed, or damaged wiring between the temperature sensor and the control board can result in poor communication, leading to errors.
- Control Board Issues: If the sensor and wiring are intact, the control board itself may be defective. It might misinterpret temperature readings or fail to regulate the oven’s heat.
- Obstructions in the Oven: Items like aluminum foil or debris can obstruct heat distribution, causing localized overheating and triggering the error.
- User Error or Settings Misconfiguration: Accidental selection of extremely high temperatures or prolonged baking cycles could cause the oven to overheat.
Tools You’ll Need
- Phillips screwdriver
- Multimeter
Safety Precautions
When working on appliances, safety is key. Follow these guidelines to minimize risks:
- Disconnect Power: Always unplug the appliance or turn off the circuit breaker before performing any maintenance. This eliminates the risk of electric shock.
- Let It Cool Down: If the oven was recently used, allow ample time for it to cool completely before starting work.
- Shut Off Gas Supply: Turn off the gas to prevent leaks during repairs.
- Organize Your Workspace: Work in a well-lit, clutter-free area. Keep children and pets away from the space.
- Dry Work Area and Hands: Ensure both your hands and workspace are dry before handling internal components.
- Use Proper Tools: Always use insulated gloves to protect against sharp parts and debris. Handle wires and terminals with non-conductive tools or insulated gloves to avoid electrical shock.
- Take Notes: Before disconnecting wires or removing components, take photos or document their connections to simplify reassembly.
- Avoid Rushing: Work methodically and carefully to prevent errors or accidents.
- Follow the Manual: Refer to your appliance’s user manual for specific instructions related to parts or repairs.
- No Live Voltage Testing: If using a multimeter, avoid testing live voltage unless you are experienced in safe handling practices.
Once you’ve gathered your tools and ensured safety measures are in place, you can start troubleshooting the issue. If needed, consult your appliance manual for specific guidance on replacing or testing the temperature sensor and related parts.
If you’re unsure or encounter complications, it’s always wise to contact a professional technician to avoid further damage or safety concerns.
How to Resolve the F6 Error Code on an LG Gas Range
Disconnect Power and Gas Supply
- Unplug the range from the power outlet.
- Shut off the gas supply to the range.
Access the Rear Panel
- Pull the range away from the wall.
- Remove the two wire covers by unscrewing them.
- Unscrew the three screws from the rear control cover and remove the cover.
- Unscrew the 16 screws from the rear back cover and remove it.
Inspect Wiring
- Ensure the range is unplugged.
- Check all wiring connections for looseness, burn marks, frays, or damage.
- Reseat any loose connections.
- Replace damaged wiring if necessary.
- Set a multimeter to continuity mode and test the wiring.
- If no continuity is detected, replace the faulty wiring.
Test the Temperature Sensor
- Verify the range is still unplugged.
- Locate the CN05 wiring connector on the main control board.
- Set a multimeter to resistance mode (Ω).
- Measure resistance between pins 1 and 2 of the CN05 connector.
- Confirm the resistance is approximately 1.09kΩ at 77°F, adjusting by 2 Ohms per degree of temperature difference.
- If resistance is out of range, replace the oven sensor.
- If resistance is within range, replace the relay control board.
Replace the Temperature Sensor (If Necessary)
- Disconnect the power and gas supply.
- Open the oven door and remove all racks.
- Locate the oven sensor on the back wall of the oven cavity.
- Remove the two mounting screws securing the sensor.
- Disconnect the sensor by pulling the wire through the oven cavity.
- Install the new sensor by attaching the wiring harness and securing it with the mounting screws.
Reassemble and Restore Connections
- Reattach the rear covers and screws.
- Push the range back into position.
- Reconnect the power and gas supply to the range.
