Understanding the D90 Error on LG Dryers

What is the D90 Error?

The D90 error code on an LG dryer indicates that the dryer’s ductwork is clogged or obstructed. It means that there is poor airflow in your dryer, which can cause longer drying times, overheating, and damage to your clothes and the appliance.

Why does the D90 Error Occur?

The most common reason for a D90 error on an LG dryer is a blocked or restricted vent system. The exhaust vent must be clear of any obstructions such as lint buildup, debris, or even bird nests. Other reasons include a faulty blower wheel or motor, or a malfunctioning thermistor sensor.

Troubleshooting Tips for the D90 Error on Your LG Dryer

Check the Vent System

One of the first things you should do when you get a D90 error code is to check your dryer vent system. Make sure it’s not kinked or damaged in any way and inspect for any blockages such as lint buildup or debris. You should also check for proper airflow outside by feeling for air coming out of the vent when running.

Clean Lint Filter and Exhaust Hose

Another common cause of restricted airflow in LG dryers is a clogged lint filter. Clean it thoroughly before running another load to see if this solves the problem. Also, inspect and clean out your exhaust hose regularly to ensure proper ventilation.


– Use a vacuum cleaner with crevice tool attachment to clean inside of exhaust hose
– Avoid using plastic vents as they can accumulate static electricity charge leading to more lint accumulation

Common Solutions for Fixing the D90 Error on an LG Dryer

Replace the Blower Wheel or Motor

If you’ve checked everything, including the vent system and lint filter, and you’re still getting a D90 error code on your LG dryer, then it could be an issue with the blower wheel or motor. If either of these components is faulty, they will not be able to move air through the dryer efficiently.

Replace the Thermistor Sensor

The thermistor sensor is responsible for monitoring the temperature inside the dryer. If it’s not functioning correctly, it may cause overheating leading to poor airflow, resulting in a D90 error code. Replacing this sensor can solve this problem.


– Always make sure that your dryer is unplugged before attempting any repairs.
– Refer to your user manual for instructions on how to replace parts.
