Is your LG fridge displaying an RT error code? Don’t panic! This common issue is usually related to a simple problem that can be easily resolved.
Understanding the LG Fridge RT Error Code
The RT error code on your LG fridge signifies a room temperature sensor error. This means there’s a problem with the sensor that measures the temperature inside your refrigerator.
The Most Common Cause: Disconnected Sensor
The most likely cause of an RT error code is a disconnected room temperature sensor. This sensor is essential for the fridge’s temperature control system to function properly.
How to Fix the RT Error Code
- Check the Sensor Wiring:
- Locate the sensor: It’s usually located near the main control board or at the top of the refrigerator.
- Inspect the wiring: Ensure that the wires connecting the sensor to the main control board are securely attached. If you find any loose or damaged wires, reconnect them properly or replace them if necessary.
- Check the wiring at the main PCB:
- Access the main control board: This board is typically located behind a panel on the back or side of your fridge.
- Inspect the wiring: Verify that the wires connecting the room temperature sensor to the main control board are secure and not damaged. If there are any issues, reconnect or replace the wires as needed.
Important Note: An RT error code will only appear if 0 or 5 volts DC is detected at the main control board. If you’re not comfortable with electrical work, it’s best to consult a professional technician to diagnose and repair the issue.
By following these steps, you should be able to resolve the RT error code on your LG fridge and restore its normal operation.
