How To Fix My LG Dryer That Shows Code D80?


LG dryers can display error codes that need to be addressed. A common fault is the D80 error code. The D80 error signifies there is an 80% blockage in the air venting system.

What is the D80 Error Code?

The D80 error code in LG dryers indicates an issue with the dryer’s venting system. This error code appears when the dryer’s exhaust duct is 80% blocked or restricted, resulting in poor airflow. The restricted airflow can cause the dryer to overheat or take longer than necessary to dry the clothes.

How to Fix D80 Error Code LG Dryers

Step 1: Check and Clean the Lint Filter

One of the primary causes of the D80 error code is lint buildup in the dryer’s venting system. Over time, lint can accumulate in the exhaust duct, lint filter, or even the dryer’s internal components, restricting airflow and triggering the D80 error code.

  1. Turn off the dryer and unplug it from the power source.
  2. Locate the lint filter, typically found at the front of the dryer or inside the door.
  3. Remove the lint filter and clean it thoroughly by using a soft brush or vacuum cleaner.
  4. Reinstall the lint filter and plug the dryer back in.

Step 2: Inspect and Clean the Exhaust Duct

A crushed or kinked exhaust duct can also lead to the D80 error code. If the duct is not properly installed or gets bent, it can restrict the airflow, causing the dryer to overheat and display the error code.

  1. Disconnect the dryer from the power source.
  2. Carefully disconnect the exhaust duct from the dryer and the vent outside.
  3. Inspect the duct for any signs of lint buildup, kinks, or damage. Clean the duct by using a long, flexible brush or a vacuum cleaner with a hose attachment.
  4. Reconnect the exhaust duct to the dryer and the vent.

Step 3: Examine the Venting System

The issue lies with the venting components themselves. Damaged or faulty venting parts, such as the exhaust duct, lint filter, or blower wheel, can restrict airflow and result in the D80 error code.

  1. Inspect the vent outside your home to ensure it is not blocked or damaged.
  2. Check the blower wheel inside the dryer for any signs of damage or lint buildup. If necessary, clean it or replace it with a new one.
  3. Test the dryer’s airflow by running a vent blockage test, if your model has this feature. Consult your dryer’s owner manual for instructions on how to perform this test.

LG D80 Questions

Q: How often should I clean the lint filter and venting system in my LG dryer?
A: It is recommended to clean the lint filter after every load and inspect the venting system at least once a year for optimal performance.

Q: Can I use a flexible exhaust duct for my LG dryer?
A: While flexible ducts can be used, rigid or semi-rigid metal exhaust ducts are recommended for better airflow and reduced chances of kinks or damage.

Q: How do I know if my dryer’s venting system is working correctly?
A: Your dryer should have good airflow, dry clothes efficiently, and not overheat. If you notice longer drying times or excessive heat, it’s time to inspect and clean the venting system.

Q: Can the D80 error code damage my LG dryer?
A: If left unaddressed, the D80 error code can cause the dryer to overheat, leading to potential damage to the appliance or even a fire hazard.

Q: What other error codes are related to venting issues in LG dryers?
A: The D90 and D95 error codes also indicate venting issues with 90% and 95% blockage, respectively, and should be addressed similarly to the D80 error code.

Ensure that your LG dryer runs efficiently and safely. Regular maintenance and cleaning of the lint filter and venting system are crucial to prevent future occurrences of the D80 error code and keep your dryer in optimal condition
