Diy Motor Mastery: How To Test An Lg Dryer Motor Like A Pro

A faulty dryer motor can be a major inconvenience, hindering your ability to complete laundry tasks. If your LG dryer is exhibiting unusual noises or failing to tumble properly, it’s essential to diagnose the problem and determine if the motor is the culprit. Here’s a step-by-step guide to help you test the LG dryer motor:

Safety Precautions

Before beginning any testing, ensure that the dryer is unplugged from the power source. Electrical work can be dangerous, so it’s crucial to exercise caution and follow safety protocols.

Gather Necessary Tools

• Multimeter
• Screwdriver (Phillips head)

Step 1: Access the Motor

1. Disconnect the dryer from the electrical outlet.
2. Remove the screws securing the rear panel of the dryer.
3. Gently pull the rear panel away from the dryer, exposing the motor and other components.

Step 2: Test for Continuity

1. Set the multimeter to the “Ohms” setting.
2. Touch one probe to the motor’s “L1” terminal and the other probe to the “L2” terminal.
3. The multimeter should read a low resistance value, typically below 10 ohms. This indicates that the motor’s windings are intact and continuous.
4. Repeat the test between the “L1” terminal and the “N” terminal, and then between the “L2” terminal and the “N” terminal.

Step 3: Test for Ground Faults

1. Set the multimeter to the “Ohms” setting.
2. Touch one probe to the motor’s frame and the other probe to each of the three motor terminals (“L1,” “L2,” and “N”).
3. The multimeter should read an infinite resistance value (open circuit) for all three tests. This indicates that the motor is not grounded and is safe to operate.

Step 4: Test the Capacitor

1. Discharge the capacitor by touching a screwdriver across its terminals.
2. Set the multimeter to the “Capacitance” setting.
3. Touch one probe to each of the capacitor’s terminals.
4. The multimeter should read a capacitance value within the range specified on the capacitor.

Step 5: Inspect the Motor

1. Visually inspect the motor for any signs of damage, such as burns, loose wires, or broken components.
2. Check the motor’s mounting bolts to ensure they are securely tightened.

Troubleshooting Common Motor Issues

• Motor not running: Check the power supply, wiring connections, and thermal fuse.
• Motor runs but doesn’t tumble: Inspect the drive belt for wear or breakage.
• Motor makes excessive noise: Check the motor bearings for wear or lubrication issues.
• Motor overheats: Inspect the air vent for obstructions and ensure the dryer is not overloaded.

Conclusion: Resolving Motor Problems

If your LG dryer motor fails any of these tests, it’s likely that the motor needs to be replaced. It’s recommended to seek professional assistance for motor replacement as it involves electrical work. By following these steps, you can accurately diagnose and troubleshoot your LG dryer motor, ensuring that your laundry appliance functions efficiently and reliably.
