LG E1 Error: Indoor Room Temperature Sensor Error
Understanding the E1 Error
The E1 error code on your LG inverter air conditioner indicates a problem with the indoor room temperature sensor. This sensor plays a crucial role in monitoring the room’s temperature and ensuring the AC operates efficiently. When the sensor malfunctions, it can lead to incorrect temperature readings, causing your AC to operate inefficiently or stop working altogether.
Causes of the E1 Error
- Faulty Sensor: The sensor itself may be defective or damaged.
- Loose or Damaged Wiring: The wiring connecting the sensor to the control board may be loose, damaged, or disconnected.
- Control Board Issues: Problems with the control board can affect the sensor’s performance.
- Environmental Factors: Dirt, dust, or other environmental factors can interfere with the sensor’s operation.

1. Check the Sensor Wiring
- Step 1: Turn off the power to the air conditioner to ensure safety.
- Step 2: Access the indoor unit and locate the room temperature sensor. Refer to your unit’s manual if needed.
- Step 3: Inspect the wiring for any signs of damage, disconnection, or loose connections.
- Step 4: If the wiring is loose, securely reconnect it. If the wiring is damaged, replace it with new wiring of the same specifications.
2. Test and Replace the Sensor
- Step 1: Use a multimeter to test the sensor’s resistance. Compare the readings with the expected values in your unit’s manual.
- Step 2: If the sensor readings are outside the normal range, the sensor is likely defective and needs to be replaced.
- Step 3: Purchase a compatible replacement sensor and install it, ensuring all connections are secure.
3. Inspect the Control Board
