Here is how I properly check if there are no blockages triggering the error code.

It is certain that d80, d90 or d95 error codes are displayed due to issues with your dryer venting, obviously because it’s blocked.

Do this thoroughly in order to be certain that there is nothing blocking the vent before trying out our troubleshooting tips to clear the error message.

  • Turn off your dryer and detach the vent hose.

  • Reattach the dryer vent. 

Turn Off Your Dryer And Detach The Vent Hose.

Removing the vent hose

Before you even attempt to start cleaning your dryer vent, you need to disconnect the appliance from the power source.

Turn it off and unplug the power cord. Then you need to detach the dryer vent from the back of your appliance. 

You can do this with a screwdriver if you have one at home. It’s simple.

Go outside of your house where the air exhaust hose leads to, find the exterior vent and also get it detached also. 

Clean The Pipe All The Way Down With a Brush

Cleaning the Dryer vent

The next step is to clean the vent all the way down and make sure there’s no sign of lints or anything inside.

You can use a dryer vent cleaning kit or brush to do this. A vacuum cleaner is also good for doing this.

It makes your work a lot easier and faster. Ensure that the outdoor vent is also checked and cleaned properly.

You want to clean inside the dryer in case there is a blockage there also. Some homeowners don’t do this and it is also part of the steps.

Reattach The Dryer Vent

Lg dryer d80 no blockage – How To Fix

By now you should have carefully inspected the venting system and also be certain that there is no blockage.

What If d80 codes are still showing after you’ve cleaned the vent hose?

Below are the next procedures to carry out in order to finally clear the error message.

  • Reset the dryer.
  • The dryer might be oversensitive.
  • Check if the dryer vent hose is squeezed or constricted. 
  • The lint trap might be clogged.
  • Reduce the length of the exhaust venting duct.
  • Replace the exhaust vent duct.
  • Reach out to the manufacturer

#1. Try resetting the dryer

This is one of the first things you should do instantly. If the lg dryer d80 error code still persists, try resetting the appliance by removing it from the wall outlet.

Wait for at least 10 to 15 minutes before plugging it back and testing if the code is gone. If it still appears, try the next method.

#2. Check If the dryer vent hose is constricted

Another reason why your dryer keeps displaying d80, d90 or d95 error codes is probably because the vent hose is too tight and constricted.

A constricted dryer vent could start to overheat and lead to a spark or fire outbreak. 

Most of the time, the exhaust vent gets tight and constricted if it’s too long. 

If your dryer vent goes up in the attic and out through the roof, go into the attic and disconnect the duct from the vent in the roof.

What you might find out is a screen before the vent might have been blocked by lints which you probably don’t know. 

Once you remove these lints at the external vent interface, the error message will probably go away.

#3. The lint filter might be clogged

Inspecting the link trap

You might not notice that the lint filter is jammed with lint.

All that is required of you is to remove the lint screen and clean up all the lint that’s there before washing and attaching it back.

#4. Reduce the length of the exhaust venting duct.

Cutting the vent hose

This is exactly what I was talking about. An exhaust venting duct which is too long would not be of any benefit to your dryer. 

A constricted venting duct will always prevent the proper flow of air and other materials via the duct.

Try to reduce the length, it might be a reason why the appliance is still detecting a blockage in the vents.

#5. Replace the exhaust vent duct 

The exhaust vent hose might need to be replaced at a particular point if you keep

having issues with it.

It is also another reason why your lg dryer keeps showing the code.

But before you get a replacement, try removing the vent hose and running the machine for a few minutes to see if the error goes away.

#6. The dryer might be oversensitive

The dryer has been programmed to detect whenever there’s an issue with the venting system.

It gets shut down in order to prevent a fire outbreak in the household.

Sometimes it gets over sensitive that it detects even a slight object in the vent hose.

What you need to do in this case is to clear the lg dryer code d80 from the display panel.

To clear the persistent error code, you need to press some buttons on the dryer in a specific sequence.

  1. If you deactivate the d80 code will it reactivate so if functions? I would assume this is important.Please advise. Thank you for your information.

    1. Hi Linda.
      If you deactivate the D80 error code on an LG dryer, it may reactivate if the underlying issue that triggered the error code in the first place is not resolved.

      The D80 error code on an LG dryer typically indicates an issue with the dryer’s air flow or venting system.

      So if you simply deactivate the error code without addressing the underlying issue, it is likely that the error code will reactivate the next time the dryer is used. I hope this helps 🙂
