D90 Error Code Explained
The LG Dryer D90 error code can be confusing. It shows up on your dryer, but there may be no clear blockage. Understanding this code helps you fix the problem faster. This section explains what the D90 code means and what causes it. It also clears up common misunderstandings about blockages. Keep reading to learn more about this error code and how to handle it.
What Triggers The D90 Code
The D90 error code usually points to a sensor or airflow problem. The dryer senses that air is not flowing correctly. This can happen even if the vent looks clear. Sometimes, the lint filter is dirty or the vent pipe is kinked. Other times, the internal sensors may fail or get dirty. The dryer stops and shows the D90 code to prevent overheating.
Common Misconceptions About Blockages
Many people think the D90 code always means a blockage. This is not true. The vent may seem fine but still cause the error. Small lint buildup inside the vent or dryer can block airflow. The problem can also come from a faulty sensor or electrical issue. Checking only the vent may not solve the problem. A full inspection of the dryer’s airflow system is needed.

Checking The Dryer’s Sensor
Checking the dryer’s sensor is a key step when the LG dryer shows the D90 error code without any blockage. The sensor tells the dryer how wet the clothes are. It helps the machine decide how long to dry the clothes. If the sensor is dirty or faulty, the dryer may stop or show errors.
Cleaning or inspecting the sensor can fix many drying problems. It is a simple task that anyone can do. This section explains how sensors affect dryer performance and how to inspect and clean them.
How Sensors Affect Dryer Performance
The sensor detects moisture in clothes during the drying cycle. It sends signals to the dryer’s control board. This helps the dryer adjust the time and heat.
If the sensor is dirty, it might send wrong signals. The dryer may stop early or run too long. It can cause the D90 error code to appear. A clean sensor keeps the dryer working well and saves energy.
Steps To Inspect And Clean Sensors
First, unplug the dryer to stay safe. Open the dryer door and locate the sensor bars. They are usually inside the drum near the door.
Look for any dirt, lint, or residue on the sensor bars. Use a soft cloth dampened with rubbing alcohol to clean them gently. Avoid harsh chemicals or scrubbing hard.
Let the sensor dry completely before closing the door. Plug the dryer back in and run a test cycle. The error code should clear if the sensor was the problem.
Power Reset And System Reboot
The LG dryer D90 error code can sometimes appear even when there is no blockage. A simple power reset and system reboot often fix this issue. This process clears minor electronic glitches and refreshes the dryer’s system. It is an easy step anyone can try before calling for repair.
Power reset and system reboot can restore the dryer’s normal function. It helps the machine to start fresh. This simple method saves time and avoids unnecessary service costs. Knowing when and how to do it is important for every user.
When To Perform A Power Reset
Try a power reset if the error code shows without any blockage. When the dryer stops working or runs slowly, reset first. If the error repeats after a cycle, a reset can help. Also, use this step if the dryer behaves strangely or freezes. Avoid resetting too often; only do it when needed.
Safe Reboot Procedures
First, unplug the dryer from the power outlet. Wait for at least five minutes before plugging it back in. This pause lets the dryer’s system clear all stored energy. After reconnecting, press the start button to reboot the machine. Do not open the dryer door during this process. Follow these steps carefully to avoid damage.

Inspecting The Dryer Vent System
Inspecting the dryer vent system is important when the LG Dryer shows a D90 error code but no blockage is found. This error can occur due to problems in the venting system that are not obvious. Checking the vent helps ensure the dryer works safely and efficiently.
Dryer vents carry hot air and moisture outside. If the vent is not clear or has issues, the dryer may overheat or stop working properly. Sometimes, the vent looks clear but still causes problems. Careful inspection can find hidden issues that affect dryer performance.
Why Venting Issues May Not Show Blockages
Venting problems do not always mean a full blockage. Lint can stick inside the vent walls, reducing airflow. Small gaps or bends in the vent pipe can trap lint. This buildup may not block the vent completely but still slows air movement.
Crushed or damaged vent pipes can also cause airflow problems. Poor vent installation or long vent runs may reduce airflow. These issues do not look like blockages but affect dryer function. Checking for these hidden problems is key.
Tools For Vent Inspection
Use a flashlight to look inside the vent pipe. A flexible vent brush helps remove lint stuck in corners. A vacuum cleaner with a hose attachment can clear lint from the vent and vent hood.
A vent inspection camera shows the inside of long or hard-to-reach vent pipes. This tool helps find damage or lint buildup not visible from the outside. Using the right tools makes vent inspection easier and more effective.
Firmware And Software Updates
Firmware and software updates help your LG dryer work better. These updates fix bugs and improve performance. Errors like the D90 code can sometimes occur due to outdated software. Keeping your dryer’s firmware up to date can solve these issues. It ensures your machine runs smoothly without blockages or other problems.
Checking For Available Updates
Start by checking if your dryer has new software updates. Visit the LG website or use the LG app on your phone. Enter your dryer model number to find updates. Some models allow you to check updates directly from the control panel. Always use a stable internet connection during the check. This step helps identify if an update can fix the D90 error.
Installing Updates To Fix Errors
Follow the instructions to download and install updates safely. Your dryer might need to be connected to Wi-Fi or a USB device. Avoid turning off the dryer while updating. The process usually takes a few minutes. After updating, restart your dryer to see if the error disappears. Installing updates often resolves software-related problems quickly.
