Overloading your dryer can also lead to damage to your clothing items, by causing them to become twisted or tangled. This can result in stretched out or misshapen clothes that may need to be replaced. By using a smaller load size, you can help preserve the quality and longevity of your clothing.

3. Blocked lint filter

Blocked lint filter is one of the most common causes of LG dryer d80 no blockage problem. The lint filter is designed to catch lint and debris that accumulates during the drying cycle.

When the filter becomes blocked, it restricts the airflow, which can cause the dryer to overheat and shut down. In this section, we will explore the points to consider when dealing with blocked lint filter issue.

One of the first things to consider when you are experiencing LG dryer d80 no blockage problem is the lint filter. To check if the filter is blocked, you can remove it from the dryer and inspect it.

If you notice any lint or debris on the filter, you will need to clean it.

To clean the lint filter, you can use a soft-bristled brush or a vacuum cleaner. Make sure to remove all the lint and debris from the filter to improve airflow.

It is important to clean the lint filter after every drying cycle. Neglecting to do so can lead to a build-up of lint and debris, which can cause the filter to become clogged. When the filter is clogged, it restricts the airflow, which can cause the dryer to overheat and shut down. Cleaning the filter regularly can prevent this issue from occurring.

4. Sensor malfunction

Sensor malfunctions in an LG dryer can be frustrating, as they often result in poor drying performance or machine failure. These problems can stem from various reasons, including faulty sensors, improper installation, or old age. 

One of the primary causes of sensor malfunctions in LG dryers is a dirty or obstructed sensor. The sensor primarily works by detecting the humidity level inside the drum, which initiates the drying process.

If this sensor is covered with lint or other debris, it will not function correctly, resulting in poor drying performance. Moreover, the sensor can get damaged if it is not cleaned routinely, leading to complete machine failure.

Another crucial point to consider is the location of the sensor. If the sensor is not placed correctly during installation, it will result in inaccurate readings, leading to either under-drying or over-drying of clothes. The sensor must be placed in a spot where it can detect the humidity level accurately, such as in the middle of the drum or near the inlet vent.

An old or faulty sensor can also cause problems in an LG dryer. Sensors can wear out over time, reducing their ability to detect the humidity level accurately. If this is the case, the sensor needs replacement, as it is no longer useful in detecting the humidity level. A technician should perform this task to ensure that the new sensor is installed correctly.

Finally, if the machine’s control board is damaged or malfunctioning, it can also lead to problems with the sensors. The control board works as the motherboard of the dryer, controlling all the machine’s functions, including the sensors. If the control board is not functioning correctly, the sensors will not work correctly, leading to poor drying performance or machine failure.

5. Dryer Vent Hose is Constricted

Dryer vent hose plays a crucial role in ensuring that your clothes come out completely dry. It is the part that directs hot, humid air out of your dryer and into the outside environment. However, one of the most common problems that dryer owners experience is constricted dryer vent hoses.

When your dryer vent hose is constricted, the airflow in your dryer is restricted, and this could lead to several problems, including LG dryer d80 no blockage errors. In this section, we will examine why dryer vent hose constrictions happen and what you need to do to fix the problem.

One of the main reasons why dryer vent hoses could get constricted is due to a buildup of lint. Dryers generate lint during drying, and this lint is supposed to be directed through the vent hose and out of the dryer. However, over time, this lint could accumulate along the vent hose, leading to a blockage. A blockage can cause hot, humid air to become trapped within the dryer instead of being vented out, thus leading to LG dryer d80 no blockage errors.

Another reason why your dryer vent hose may be constricted is due to poor installation. If your dryer vent hose is not installed correctly, it could become twisted or kinked, thus restricting the airflow in the dryer. This could also cause LG dryer d80 no blockage errors as the vent hose is not properly directing air out of the dryer.

Other causes of dryer vent hose constrictions include using a vent hose that is too long, using a vent hose with too many bends, a damaged or clogged vent cap, or a vent hood that is not suitable for your dryer.

To fix a constricted dryer vent hose, you need to first locate the blockage and remove it. If you cannot locate the blockage, you may need to call a professional to do it for you. You can also consider replacing a badly damaged or old vent hose to improve the airflow in your dryer.
