What Causes the LG Dryer D80 Error Code?

The D80 error code on your LG dryer is typically caused by restricted airflow. Several factors can contribute to this issue, all of which lead to your dryer overheating and triggering the D80 error code.

  1. Clogged or Blocked Ductwork: One of the most common causes of the D80 error code is clogged ductwork or a blocked dryer vent. When the airflow through these parts is obstructed, it prevents the hot air from being vented properly, causing the dryer to overheat.
  2. Poor Ventilation: If your dryer is located in a cramped or poorly ventilated area, it will struggle to release heat, resulting in overheating. Additionally, if the ductwork is improperly placed or even crushed, it can cause the dryer to overheat and trigger the D80 error code.
  3. Malfunctioning Components: If the duct sensors or heat removal system in your dryer are malfunctioning, they might falsely detect a blockage, causing the D80 error code to appear even if there is no physical obstruction.
  4. Lint Buildup: Lint buildup in the lint filter or dryer exhaust is another frequent culprit. If left unchecked, lint can accumulate and obstruct the airflow, leading to overheating and the appearance of the D80 error code.
  5. Improper Vent Installation or Design: In some cases, the vent installation or design may be flawed, making it difficult for your dryer to vent air properly. This can cause heat buildup and trigger the D80 error code.

By identifying and addressing these issues, you can clear the D80 error code and restore your dryer to optimal performance.

What is LG Flow Sense and Why Does It Exist?

LG’s Flow Sense technology is a built-in feature found in certain LG dryers that helps monitor and manage airflow within the appliance. The system works using a pressure switch to measure the air being blown through the dryer’s vents and a heat sensor that detects if the dryer is reaching dangerous heat levels. This dryer’s ventilation system ensures that airflow remains consistent, and if there is any restriction, it triggers an alert.

When the airflow is restricted, often due to buildup like lint in the dryer’s vent, the Flow Sense system is designed to warn the user with an indicator on the user-interface panel. The more restricted the airflow, the less air is being blown through the system, which leads to inefficient drying and potentially dangerous overheating.

This technology is crucial because it notifies users before a fire hazard becomes a serious issue. Without Flow Sense, a dryer could operate for a longer period with poor ventilation, increasing the risk of overheating and even catching fire. The Flow Sense feature helps prevent these hazards by providing an early warning system, encouraging users to clean their dryer before a more severe issue arises.

If your dryer shows a ‘D80’ code with several bars on the gauge, this indicates that airflow is significantly restricted. This warning is not only about improving drying performance but also about ensuring the appliance operates safely. By addressing the ventilation issues early, you can avoid the more severe blockages and keep your dryer running efficiently and safely.

Why You Should and Shouldn’t Bypass a D80 Error Code?

Bypassing a D80 error code might seem like a quick fix if you need to use your dryer right away, but it can lead to serious problems.
