Lg Dryer’S Relentless Running: The Root Causes Revealed

If your LG dryer keeps running without stopping, it can be a frustrating and puzzling issue. There are several potential reasons why this may occur, from minor glitches to more serious problems. In this comprehensive guide, we will delve into the possible causes and provide step-by-step instructions on how to troubleshoot and resolve the issue.

Common Causes and Solutions

1. Clogged Lint Trap

One of the most common causes of a dryer running continuously is a clogged lint trap. Lint buildup can block airflow, causing the dryer to overheat and continue running indefinitely. To resolve this issue:

• Unplug the dryer.
• Remove the lint trap and clean it thoroughly.
• Vacuum any lint that may have accumulated around the lint trap housing.

2. Faulty Door Switch

The door switch is responsible for detecting when the dryer door is closed. If the switch is faulty, the dryer may continue to run even when the door is open. To check the door switch:

• Unplug the dryer.
• Open the dryer door and locate the door switch.
• Test the switch with a multimeter to ensure continuity.
• Replace the switch if it is faulty.

3. Overheating Thermistor

The thermistor is a temperature sensor that monitors the heat inside the dryer. If the thermistor fails, it may send incorrect temperature readings, causing the dryer to overheat and continue running. To check the thermistor:

• Unplug the dryer.
• Locate the thermistor, which is typically near the heating element.
• Test the thermistor with a multimeter to ensure proper resistance.
• Replace the thermistor if it is faulty.

4. Defective Timer

The timer controls the drying cycle. If the timer is defective, it may fail to advance, causing the dryer to run indefinitely. To check the timer:

• Unplug the dryer.
• Locate the timer and turn the dial manually.
• If the timer does not advance or if there is any resistance, it may be defective.
• Replace the timer if necessary.

5. Worn Drive Belt

The drive belt connects the motor to the dryer drum. If the belt is worn or broken, it may slip, causing the drum to stop rotating and the dryer to continue running. To check the drive belt:

• Unplug the dryer.
• Open the dryer door and locate the drive belt.
• Inspect the belt for signs of wear or breakage.
• Replace the belt if necessary.

6. Faulty Motor

The motor is the heart of the dryer. If the motor fails, the dryer will not be able to rotate the drum. To check the motor:

• Unplug the dryer.
• Locate the motor and check for any signs of damage or burning.
• Test the motor with a multimeter to ensure continuity.
• Replace the motor if it is faulty.

7. Electrical Issues

In some cases, electrical issues can cause the dryer to run continuously. These issues can include:

• Faulty wiring
• Loose connections
• Power surges
• Circuit breaker trips

If you suspect an electrical issue, it is recommended to consult a qualified electrician.

Troubleshooting Tips

Before attempting any repairs, always unplug the dryer for safety. If you are not comfortable with any of the troubleshooting steps, it is best to contact a qualified appliance repair technician.
