The Ultimate Guide: How to Test LG Washer Control Board Like a Pro!

Your LG washer is a reliable workhorse, but even the best appliances can encounter issues. One common culprit? The control board, the brains of your washing machine. If your washer is displaying strange error codes, refusing to start, or behaving erratically, the control board might be the culprit. Knowing how to test LG washer control board can save you a trip to the repairman and potentially a hefty repair bill. Let’s dive into the world of LG washer control board troubleshooting!

Understanding the LG Washer Control Board

The control board is the electronic heart of your LG washer. It’s responsible for receiving input from the control panel, interpreting commands, and sending signals to various components like the motor, water valves, and heating elements. A faulty control board can lead to a range of problems, including:

• Failure to start: The washer might not power on at all.
• Erratic operation: The washer might start but then stop abruptly, cycle through functions randomly, or display error codes.
• Incorrect water levels: The washer might fill with too much or too little water.
• Heating problems: The washer might not heat water properly.
• Spin issues: The washer might not spin or spin too slowly.

Visual Inspection: The First Step

Before diving into electrical testing, always start with a visual inspection. This can help you identify any obvious problems:

• Burnt components: Look for any burnt or charred areas on the control board. This indicates a serious issue.
• Loose connections: Check the wiring harness for loose or disconnected wires.
• Physical damage: Look for any signs of physical damage, like cracks or broken components.

Testing the Control Board: A Step-by-Step Guide

If the visual inspection doesn‘t reveal any issues, you’ll need to test the control board itself. Here’s how:
1. Disconnect Power: Before you begin, always unplug the washing machine from the power outlet. Safety first!
2. Locate the Control Board: The control board is typically located behind the control panel. You might need to remove screws or clips to access it.
3. Identify the Components: The control board will have a variety of components, including:

• Relay: A relay is an electrically controlled switch that opens and closes circuits.
• Capacitor: A capacitor stores electrical energy.
• Resistor: A resistor limits the flow of electricity.
• Diode: A diode allows electricity to flow in one direction only.

4. Use a Multimeter: A multimeter is an essential tool for testing electronic components. It can measure voltage, current, and resistance.
5. Test the Relay: To test a relay, set your multimeter to the continuity setting. Touch the probes to the terminals of the relay. If the relay is working, the multimeter should show continuity (a closed circuit) when the relay is energized.
6. Test the Capacitor: To test a capacitor, set your multimeter to the capacitance setting. Touch the probes to the terminals of the capacitor. The multimeter should display the capacitance value of the capacitor.
7. Test the Resistor: To test a resistor, set your multimeter to the resistance setting. Touch the probes to the terminals of the resistor. The multimeter should display the resistance value of the resistor.
8. Test the Diode: To test a diode, set your multimeter to the diode setting. Touch the probes to the terminals of the diode. The multimeter should display a reading when the probes are connected in the forward direction.

Interpreting the Results

If you find any components that are not working properly, you’ll need to replace them. You can usually find replacement components online or at an appliance parts store.

Replacing the Control Board

If you’ve tested all the components and they’re working properly, the control board itself is likely faulty. Replacing the control board is a more complex task, and you’ll need to follow the instructions provided with the new control board.

Troubleshooting Tips: Avoiding Common Pitfalls

• Don’t rush: Take your time and be careful when working with electrical components.
• Use the right tools: A multimeter is essential for testing the control board.
• Refer to the service manual: The service manual for your LG washer will provide detailed instructions on how to test and replace components.
• Safety first: Always disconnect the washer from the power outlet before working on it.

When to Call a Professional

If you’re not comfortable working with electrical components or if you’re unable to diagnose the problem, it’s best to call a qualified appliance technician. They have the experience and tools to properly diagnose and repair your LG washer.

Final Thoughts: A Fresh Start for Your Laundry

Learning how to test LG washer control board empowers you to troubleshoot common washer issues. Remember, a visual inspection and multimeter are your best friends when tackling this task. If you’re unsure, don’t hesitate to call a professional for help. With a little knowledge and a few tools, you can keep your LG washer running smoothly for years to come!
