How to Troubleshoot LG Washer Motor Sensor Error

LG washers are equipped with advanced motor sensor technology that helps in detecting any potential issues and ensuring efficient performance. However, at times, you may face motor sensor error on your LG washer, leading to malfunctions or even complete shut down. In this step-by-step guide, we will walk you through the troubleshooting process to resolve the LG washer motor sensor error.

Step 1: Identify the Error Code

When your LG washer encounters a motor sensor error, it will display an error code on the control panel. Before proceeding with the troubleshooting, it is crucial to identify the specific error code as it will help in narrowing down the root cause and determining the appropriate solution.

Step 2: Power Cycle the Washer

Many times, a simple power cycle can resolve minor issues with the motor sensor. To power cycle your LG washer, follow the steps below:

1. Unplug your washer from the power outlet and wait for approximately 1 minute.
2. Plug the washer back into the power outlet.
3. Turn on the washer and check if the motor sensor error has been fixed.

Step 3: Check the Motor Sensor Wiring

Improper or loose wiring connections can trigger motor sensor errors. Ensure that all the connections to the motor sensor are secure and properly seated. Inspect the wiring harness for any signs of damage or fraying. If any issues are found, repair or replace the wiring accordingly.

Step 4: Examine the Rotor Position Sensor (RPS)

The Rotor Position Sensor (RPS) is responsible for detecting the position of the motor rotor. If the RPS is faulty or misaligned, it can cause motor sensor errors. Follow these steps to examine the RPS:

1. Locate the RPS, usually positioned near the motor.
2. Inspect the RPS for any signs of damage, such as corrosion or loose connections.
3. Clean the RPS contacts using a soft brush to remove any dirt or debris.
4. Ensure that the RPS is properly aligned and securely installed.
5. If the RPS is damaged or misaligned, consider replacing it with a new one.

Step 5: Reset the Control Board

Resetting the control board can often resolve electronic glitches that cause motor sensor errors. Please note that the steps to reset the control board may vary depending on the specific LG washer model. Refer to the user manual or contact LG customer support for instructions on how to reset the control board.

Step 6: Consult Professional Service

If none of the above troubleshooting steps resolve the motor sensor error on your LG washer, it is advisable to seek professional assistance. Contact a certified LG technician or schedule a service appointment to diagnose and repair the issue accurately.

By following these steps carefully, you should be able to troubleshoot and resolve the motor sensor error on your LG washer. Regular maintenance and proper care of your washer can help prevent future errors and ensure smooth performance. Always refer to the user manual and follow safety precautions while performing any troubleshooting or repair tasks.
