Troubleshooting Your Lg Dryer’S Knocking Nightmare: Causes And Solutions Revealed

If you’re experiencing a persistent knocking sound from your LG dryer, it can be a frustrating and concerning issue. To effectively troubleshoot the problem, it’s crucial to understand the potential causes and identify the best solution. This comprehensive guide will delve into various reasons why your LG dryer may be knocking and provide detailed steps to resolve the issue.

Common Causes of Knocking in LG Dryers

1. Loose or Worn Drum Support Rollers

The drum support rollers are responsible for supporting the dryer drum during rotation. Over time, these rollers can become loose or worn, leading to excessive movement and knocking noises.

2. Malfunctioning Belt

The belt drives the dryer drum. If the belt becomes loose, worn, or damaged, it can slip or jump, causing a knocking sound.

3. Loose or Damaged Drum Baffles

Drum baffles are designed to reduce noise and vibrations during the drying cycle. However, loose or damaged baffles can become dislodged and cause knocking noises.

4. Worn or Damaged Motor Coupling

The motor coupling connects the motor to the drum. If the coupling becomes worn or damaged, it can cause the drum to wobble and produce knocking noises.

5. Foreign Objects

Foreign objects, such as coins, keys, or clothing, can become trapped in the dryer drum or other components, causing knocking noises.

6. Uneven Floor

If the dryer is installed on an uneven floor, it can cause the drum to wobble and knock.

7. Overloading

Overloading the dryer can put excessive strain on the components, leading to knocking noises and potential damage.

Troubleshooting and Repair Steps

1. Check for Foreign Objects

Open the dryer door and remove any loose items from the drum and surrounding areas.

2. Inspect Drum Support Rollers

With the dryer unplugged, gently move the drum back and forth. If you feel excessive play or hear a grinding noise, the rollers may need to be replaced.

3. Examine the Belt

Disconnect the dryer from power and remove the back panel. Check for any signs of wear, fraying, or damage on the belt. If necessary, replace the belt.

4. Tighten Drum Baffles

Open the dryer door and locate the drum baffles. If they are loose, use a screwdriver to tighten the screws that secure them in place.

5. Inspect Motor Coupling

Locate the motor coupling and check for any signs of wear or damage. If necessary, replace the coupling.

6. Level the Dryer

Place a level on top of the dryer to check if it’s level. If not, adjust the leveling feet accordingly.

7. Reduce Load Size

Avoid overloading the dryer and follow the manufacturer’s recommended load sizes.
