Common Reasons Why Your LG Dryer Keeps Stopping Unexpectedly: Causes and Fixes

Experiencing issues with your LG dryer, such as it stopping unexpectedly, can be frustrating. However, understanding the common causes behind this issue can help you troubleshoot and find a solution. 

In this article, we’ll explore the most frequent reasons why an LG dryer stops prematurely and provide tips on how to fix the problem. Whether your LG dryer keeps shutting off early, or you’re dealing with a unit that turns off in the middle of a cycle, we have the insights you need.

Key Takeaways

• Overheating due to clogged vents or restricted airflow is a primary cause of dryers shutting off unexpectedly.
• Thermal fuses and moisture sensors are common components that can malfunction, leading to early shutdowns.
• Professional service is recommended if troubleshooting steps don’t resolve the issue or if you’re dealing with more complex problems, like a defective control board.
• Regular maintenance, such as cleaning the lint filter and vent system, can prevent many of the issues that cause your dryer to stop unexpectedly.

Common Causes of an LG Dryer Stopping Unexpectedly

If your LG dryer keeps stopping unexpectedly, there are several possible causes that you should check. Understanding LG dryer issues can help you pinpoint the specific problem affecting your appliance.

1. Overheating and Thermal Fuse Activation

Dryers are equipped with thermal fuses designed to prevent overheating. If the dryer becomes too hot, the thermal fuse will blow, causing the dryer to stop to prevent further damage or potential fire hazards. This is often due to restricted airflow. One common sign of airflow issues is the appearance of LG Dryer Code D80. This error code indicates a significant reduction in airflow, usually caused by a clogged vent or duct. When this occurs, the dryer automatically shuts off to avoid overheating. 

Fix: Inspect and clean the lint filter, vent hose, and exhaust vent to ensure proper airflow. If the thermal fuse is blown, it will need to be replaced. 

2. Faulty Door Switch

The door switch ensures the dryer operates only when the door is securely closed. If the switch is malfunctioning, it may cause the dryer to stop unexpectedly. 

Fix: Test the door switch for continuity using a multimeter. If defective, replace the door switch. 

3. Clogged Vent System

A clogged vent system can lead to overheating, causing the dryer to shut off prematurely. This is a common issue and can be a fire hazard if not addressed. 

Fix: Regularly clean the lint filter after each use and have the vent system professionally cleaned at least once a year. 

4. Malfunctioning Moisture Sensor

Modern dryers use moisture sensors to detect the dryness of clothes. If these sensors are dirty or malfunctioning, they may cause the dryer to stop prematurely. 

Fix: Clean the moisture sensors with a soft cloth and mild detergent. If cleaning doesn’t help, the sensor may need to be replaced.

5. Overloaded Dryer

Overloading the dryer can cause it to overheat and shut off to prevent damage. It also reduces drying efficiency. 

Fix: Avoid overloading the dryer. Follow the manufacturer’s guidelines for load sizes.

6. Electrical Issues

Power supply problems, such as a tripped circuit breaker or faulty power cord, can cause the dryer to stop unexpectedly. 

Fix: Check the circuit breaker and reset if necessary. Inspect the power cord for any visible damage. 

7. Defective Control Board

The control board manages the dryer’s functions. A malfunctioning control board can cause the dryer to stop unexpectedly.

Fix: If other solutions don’t resolve the issue, the control board may need to be replaced.

Troubleshooting Steps

To resolve the issue of an LG dryer turning off unexpectedly, you can follow some easy troubleshooting steps.

1. Unplug the Dryer: Always disconnect the power before inspecting or repairing the dryer. 
2. Inspect the Lint Filter and Vent System: Ensure they are clean and free from obstructions.
3. Test the Door Switch: Use a multimeter to check for continuity. 
4. Clean the Moisture Sensors: Gently wipe them with a soft cloth.
5. Check for Overloading: Ensure the load size is appropriate. 
6. Examine the Power Supply: Inspect the power cord and check the circuit breaker.
7. Consult a Professional: If the issue persists, seek professional assistance.
