LG dryers are premium-quality appliances equipped with advanced safety features. A key aspect of their design is their ability to display specific error codes when there are issues with the appliance or its ventilation system. Here, we’ll walk you through how to quickly fix the most common error codes: D80, D90, and D95.

Understanding the Most Common Error Codes

If your LG appliance dryer’s control board displays error codes D80, D90, or D95, it means there is an issue with airflow, usually caused by lint buildup. The higher the error code, the more severe the obstruction. These codes are designed to shut down the appliance to prevent overheating, ensuring the safety of your home.

Step-by-Step: Fixing the D80 Error Code

When the D80 code appears, it means 80% of the airflow is obstructed. Lint buildup in the exhaust pipe or other ventilation components commonly causes this.

Here’s how to fix it:

1. Clean the lint filter thoroughly before replacing it.
2. Unplug the exhaust hose located at the back of the dryer.
3. Inspect the hose for clogs and remove any lint or debris.
4. Examine the wall duct for blockages and clean thoroughly if necessary. For deeper cleaning, consider using a vent cleaning kit.
5. Check the exterior vent, ensuring any blockages are cleared and the vent flaps open fully.

If these steps don’t resolve the issue, or the error persists after restarting the dryer, contact a professional appliance repair company.

Step-by-Step: Fixing the D90 Error Code

When your LG dryer displays the D90 code, it means 90% of the airflow is blocked, causing a severe restriction in the ventilation system. Here’s how to fix it:

1. Clean the lint filter: Ensure the filter is thoroughly cleaned before replacing it.
2. Unplug the exhaust hose: Disconnect the hose from the back of the dryer and check for blockages.
3. Inspect and clean the wall duct: Use a vent cleaning kit to reach deep into the wall duct and remove any obstructions.
4. Clear the exterior vent: Check the outdoor vent for blockages or debris, ensuring the vent flaps open fully.
5. Restart the dryer: After clearing all blockages, restart the dryer to see if the error persists.

If the error remains, contact a professional technician for further diagnosis.

Step-by-Step: Fixing the D95 Error Code

The D95 code indicates that 95% of the airflow is blocked, making it the most severe ventilation issue. To fix it:

1. Vacuum the exhaust hose: Use a vacuum cleaner to remove lint, debris, and dirt from the exhaust hose.
2. Clean the wall duct: Use a vent brush or cleaning kit to clean the wall duct of any obstructions thoroughly.
3. Inspect and clean the exterior vent: Ensure the outside vent is free of any blockages and that the flaps can open without restriction.
4. Restart the dryer: After cleaning, restart the appliance to clear the error code.

If the D95 error persists, it’s crucial to contact a professional, as this level of blockage may require specialized tools or a more thorough inspection of the dryer’s ventilation system.

When to Call a Professional

Call an authorized professional if LG dryer error codes (D80, D90, D95) persist after cleaning, if blockages are hard to reach, or if you encounter damaged parts, electrical issues, or frequent overheating. Also, seek help for strange noises, odours, or unclear error codes. A pro ensures safe, effective repairs and can diagnose complex problems that DIY solutions may miss.

As a homeowner, regular dryer maintenance is key to ensuring safety and efficiency. By cleaning vents and lint filters on time, you not only prevent costly breakdowns but also reduce the risk of fire hazards caused by blocked airflow. Staying proactive with maintenance is essential for keeping your appliance running smoothly and extending its lifespan.
