How to fix error D90?
To resolve the D90 error code and restore your dryer’s functionality, you need to clear the blockage in the dryer’s ventilation system. Follow these steps to remove the error code:
1. Clean the lint filter
A clogged lint filter is the most common cause of this error code. When the lint filter is not cleaned regularly, it can cause a buildup of lint, restricting the airflow and leading to inefficient drying. Locate the lint filter, remove it, and clean it thoroughly. Make sure to remove all lint before placing it back into the dryer.
2. Disconnect the exhaust hose
The exhaust hose connected to the back of the dryer can become blocked with lint or debris, causing a restriction in the airflow. Pull the dryer away from the wall and disconnect the exhaust hose from the back of the dryer. Check for any blockages and remove any lint or debris present in the hose. You can use a vacuum cleaner to remove lint effectively.
3. Inspect the wall duct
The ductwork within the walls of your home can also accumulate lint, leading to blockages. Check the wall duct for any blockages and remove them if present.
4. Examine the exterior vent
The exterior vent, which expels the hot air from the dryer, can become blocked with lint or other debris, impeding proper airflow. If you have access to the exterior vent, check for any blockages and remove them.
Reassemble and test
Once all components of the ventilation system have been cleaned, reattach the exhaust hose, and position the dryer back in place. Plug the LG dryer back into the power outlet, then check if the error code has cleared or has been reset. If the error code keeps showing on the display, try resetting the dryer.
