What Does D90 Error Mean on LG Dryer? Troubleshooting Tips Included

What Does D90 Mean on Lg Dryer?

The code “D90” on an LG dryer indicates a 90% blockage in the exhaust duct.

This means that there is a potential blockage in the duct work of the dryer, which can be caused by lint buildup and debris in the exhaust system.

To resolve this issue, you can try cleaning the lint filter, checking the outside dryer air vent for strong airflow, and removing any visible obstructions.

However, if the blockage is not visible or if the ductwork has many bends, it may be necessary to hire a professional for duct cleaning.

It is important to address this issue promptly, as using a dryer with a severely restricted exhaust is unsafe and should be avoided until the system is cleaned and repaired.

Key Points:

  • “D90” on an LG dryer means a 90% blockage in the exhaust duct
  • Lint buildup and debris can cause this blockage
  • Solutions include cleaning the lint filter and checking the outside dryer air vent for airflow
  • If the blockage is not visible or if the ductwork has many bends, professional help may be needed
  • Using a dryer with a severely restricted exhaust is unsafe and should be avoided
  • Promptly addressing the issue is important for safety.

Did You Know?

1. The term “D90” on an LG dryer stands for “Degree of Dryness” and refers to the highest level of dryness that can be selected for a specific load of laundry.

2. LG dryers with the D90 feature utilize advanced sensor technology to detect the moisture content in the clothes, allowing them to automatically adjust the drying time to achieve the selected level of dryness.

3. The D90 setting on an LG dryer is particularly useful for delicate or sensitive garments that require a shorter drying time to prevent damage or shrinking.

4. LG dryers often offer a range of drying levels, including Damp Dry, Less Dry, Normal Dry, More Dry, and Very Dry. The D90 level is typically selected for heavy fabrics or items that need to be completely dry, such as towels or jeans.

5. In some models, the D90 setting on an LG dryer can also be customized to suit individual preferences by adjusting the selected level of dryness using the control panel or smartphone app, allowing for even more control over the drying process.

LG Dryer Duct Blockage Sensor

LG dryers feature a duct blockage sensor that is specifically designed to identify potential obstructions in the exhaust ducts. This sensor plays a critical role in ensuring the safety and efficiency of the dryer.

In the event of a blockage detection, the dryer’s display panel will prompt an error code. Two error codes associated with duct blockage are D90 and D95, which indicate a blockage of 90% or 95% respectively in the ductwork. These error codes serve as a warning, emphasizing the need for immediate action to address the blockage issue.

Understanding D90 and D95 Error Codes

When you encounter the D90 or D95 error codes on your LG dryer, it means that there is a significant blockage in the exhaust system. These codes are a clear indication that the airflow in the ductwork is severely restricted, potentially compromising the dryer’s performance and safety.

The numbers in the error codes correspond to the percentage of blockage in the ductwork. For instance, a D90 code signifies a 90% blockage, while a D95 code indicates a 95% blockage. These precise measurements highlight the severity of the obstruction and emphasize the urgency in resolving the issue.

Causes Of Blockages In LG Dryer Exhaust System

A variety of factors can contribute to blockages in the exhaust system of an LG dryer. One common cause is lint buildup. Over time, lint can accumulate within the dryer’s exhaust system, impeding the flow of air and leading to obstructions.

In addition to lint, other forms of debris such as dirt, dust, and even small objects can find their way into the exhaust system, contributing to blockages. Furthermore, damaged or crushed exhaust ducts can restrict the airflow, causing blockages as well.

Another factor to consider is the structure of the ductwork. If the duct runs are unusually long or have multiple bends, it can create an environment prone to blockages. These bends and extended runs provide more opportunities for lint and debris to get trapped, making it essential to take proactive measures to prevent obstructions.

Possible Solutions For Clearing Duct Blockages

Here are some troubleshooting tips to address and clear duct blockages in your LG dryer:

  • Clean the lint filter: Regularly removing lint from the filter is a simple yet effective way to prevent potential obstructions and ensure proper airflow.
  • Check the outside dryer air vent: Inspect the vent for strong airflow. A lack of sufficient airflow could indicate a blockage within the exhaust system. Clear the vent hood of any lint or debris and ensure it is not damaged or clogged.
  • Inspect the surrounding area: Look for any visible obstructions around the vent hood that might hinder the airflow. Clear away debris or objects that may have accumulated near the vent hood.

Note: Some blockages may not be apparent or easily accessible. If the ductwork has many bends or is exceptionally long, consider seeking the assistance of a professional duct cleaning service. These experts have the tools and expertise to thoroughly clean the ducts, removing any hidden blockages that may be causing the issue.

Hidden Blockages And Professional Duct Cleaning

Certain blockages may not be visible to the naked eye, especially in cases where there are long duct runs with numerous bends. These obstructions can be challenging to identify and clear. In such situations, the expertise of a professional duct cleaning service becomes invaluable.

Professionals use specialized equipment to effectively clean the inner surfaces of ducts and remove any accumulated lint, debris, or obstructions. By thoroughly cleaning the entire ductwork, they ensure that the airflow is restored and any further issues with blockages are prevented.

It is worth noting that professional duct cleaning services are not always required. If the blockage is easily accessible and not deeply embedded within the system, you may be able to resolve the issue yourself using the tips mentioned earlier. However, for stubborn or hidden blockages, seeking professional assistance is a wise decision.

Safety Precautions For Restricted Exhaust Systems

Using a dryer with a severely restricted exhaust system is not only inefficient but also hazardous. It is crucial to prioritize safety and take necessary precautions when dealing with blocked exhaust ducts.

A restricted exhaust system can cause the dryer to overheat, potentially leading to a fire. Therefore, if your LG dryer displays the D90 or D95 error codes, it is recommended that you refrain from using the appliance until the blockage is cleared and the system is cleaned and repaired.

By following the troubleshooting steps outlined earlier and addressing the blockage promptly, you can effectively ensure the safe and efficient operation of your LG dryer.

  • D90 error code indicates a 90% blockage in the exhaust ducts
  • Causes of blockage may include lint buildup, debris, damaged ducts, and long duct runs with multiple bends

Essential steps to address the issue:

  • Clean the lint filter
  • Check airflow through the vent
  • Remove any visible obstructions

Always prioritize safety and avoid using the dryer until the system is cleared and repaired.
