Exclusive Tips: How to Test LG Dryer Motor and Boost Your Laundry Game

Is your LG dryer humming but not heating? Or perhaps it’s making strange noises and struggling to spin? These could be signs of a faulty dryer motor. Knowing how to test an LG dryer motor can save you time and money. This comprehensive guide will walk you through the process, step-by-step, so you can diagnose the problem and determine if you need a replacement.

Why is My LG Dryer Motor Not Working?

Dryer motors are responsible for rotating the drum, which is essential for tumbling clothes and efficiently drying them. Over time, these motors can wear down due to regular use, leading to a variety of issues:

• Lack of power: The motor may not have enough power to spin the drum, resulting in slow or no rotation.
• Unusual noises: Grinding, clicking, or rattling sounds can indicate a worn-out motor bearing or a loose component.
• Overheating: A faulty motor can overheat, potentially leading to a fire hazard.
• Burning smell: A burnt smell emanating from the dryer could signal a motor winding problem.

Safety First: Power Down Your Dryer

Before starting any troubleshooting, it’s crucial to disconnect the dryer from the power source. This prevents electrical shock and ensures your safety.

How to Test an LG Dryer Motor: Visual Inspection

1. Locate the dryer motor: The motor is typically found at the back of the dryer, near the bottom. It might be covered by a panel or a removable access door.
2. Inspect for visible damage: Look for any signs of burning, fraying wires, or loose connections. If you notice any damage, it’s likely the motor needs replacement.
3. Check the motor belt: Ensure the belt is intact and not frayed or broken. A damaged belt can prevent the drum from spinning.

Testing the Motor with a Multimeter

If the visual inspection doesn‘t reveal any obvious issues, you can use a multimeter to test the motor’s continuity and resistance.
1. Set the multimeter to ohms: This setting allows you to measure resistance, which is a common way to test electrical components.
2. Identify the motor terminals: The motor will have two or more terminals, usually marked with letters or numbers.
3. Connect the multimeter probes: Touch the probes to the motor terminals and observe the reading on the multimeter. A reading of zero ohms indicates a short circuit, while an infinite reading suggests an open circuit. Both scenarios signify a faulty motor.

Checking the Motor with a Power Source

If the multimeter tests indicate a healthy motor, you can test it with a power source. This will help determine if the motor is receiving power or if the problem lies elsewhere.
1. Disconnect the dryer from the power source.
2. Locate the motor wires: Identify the wires connected to the motor terminals.
3. Connect a temporary power source: Using a 12-volt battery or a power supply, carefully connect the wires to the power source. Be extremely cautious with this step to avoid electrical shock.
4. Observe the motor: If the motor spins when connected to the power source, it indicates the motor itself is functional. However, if it doesn’t spin, the problem might be with the wiring or the control board.

Troubleshooting a Faulty Motor

If your tests indicate a faulty motor, you’ll need to replace it. Here’s what you need to do:
1. Order a replacement motor: Find a compatible motor for your LG dryer model. You can search online or visit a local appliance parts store.
2. Disassemble the dryer: Carefully remove the back panel or access door to reach the motor.
3. Disconnect the old motor: De-connect the wires from the old motor and remove it.
4. Install the new motor: Connect the wires to the new motor, making sure they are securely attached.
5. Reassemble the dryer: Put the back panel or access door back in place.
6. Test the dryer: Plug the dryer back in and run a test cycle to ensure the new motor is working properly.

Beyond the Motor: Other Possible Causes

While a faulty motor is a common culprit for dryer problems, other issues could be contributing to your dryer’s malfunction. Consider these possibilities:

• Broken belt: A broken belt can prevent the drum from spinning.
• Faulty control board: The control board sends signals to the motor, and a malfunctioning board can cause the motor to fail.
• Clogged vent: A clogged vent restricts airflow, leading to overheating and potential motor damage.
• Door switch: A faulty door switch can prevent the dryer from starting, even if the motor is working.

Call for Professional Help

If you’re unsure about testing the motor or if you’re uncomfortable working with electrical components, it’s best to call a qualified appliance technician. They have the expertise and tools to diagnose and repair your dryer efficiently and safely.
