by

LG dryers can experience problems. LG dryers can show the D90 error code. The D90 error code means there is an issue with airflow. This will show how to fix it.

What is LG Dryer Error Code D90?

The D90 error code in LG dryers indicates that there is restricted airflow in the dryer’s exhaust system. This typically occurs when the dryer vent or lint filter is clogged, causing the dryer to overheat and potentially leading to more severe problems, such as a broken thermostat or even a fire hazard.

Causes of Error Code D90 in LG Dryers

  1. Clogged Lint Filter A common cause of the D90 error code is a clogged lint filter. The lint filter should be cleaned after every use to prevent buildup and maintain proper airflow.
  2. Blocked or Kinked Dryer Vent The dryer vent can become blocked or kinked over time, causing restricted airflow and triggering the D90 error code.
  3. Damaged or Disconnected Vent Hose A damaged or disconnected vent hose can also cause restricted airflow, leading to the D90 error code.
  4. Faulty Exhaust Thermistor In some cases, the D90 error code may be caused by a faulty exhaust thermistor. This component monitors the temperature of the exhaust air and sends this information to the dryer’s control board. If it’s not functioning correctly, it can cause the D90 error code to appear.

How to Fix LG Dryer Error Code D90

  1. Clean the Lint Filter The first step in fixing the D90 error code is to clean the lint filter. Remove the lint filter from the dryer and use a brush or vacuum to remove any lint buildup. Be sure to clean the filter after each use to prevent future issues.
  2. Inspect and Clean the Dryer Vent Next, inspect the dryer vent for any blockages or kinks. Disconnect the vent hose from the dryer and use a vent brush or vacuum to clean out any lint or debris. Additionally, check the vent on the outside of your home to ensure it’s not blocked by leaves, snow, or other debris.
  3. Check and Replace the Vent Hose If the vent hose is damaged or disconnected, it will need to be replaced. Ensure that the new hose is properly connected and free from kinks or damage.
