LG dryers are known for being superior appliances. Not only are they nice to look at, but they are smart dryers.
In fact, they are so smart that they will tell you exactly what type of malfunction they’re having through the use of error codes.
While no one wants an error code to pop up, they are convenient because all you have to do is decipher what it means and make the repair.
Today we will discuss LG dryer codes d80, d90, and 95. We’ll explain what each code means, and how to fix them.
What Does Flow Sense or d80, d90, or d95 Error Codes Mean?
The Control panel on your LG dryer displays 4 bars illuminated by Flow Sense.
D80, D90, D95 error codes on LG dryer indicate poor airflow caused by lint restriction in the vent line or flexible vent hose. A higher number, let’s say D90 – higher restriction.
This can result in your dryer shutting down to avoid overheating which can pose a fire risk.
Flow Sense: How it Works and What Causes the Errors
Approximately 80% of residential home fires in North America begin inside a dryer. The main cause of dryer fires can be one of several things:
- The exhaust vent for the dryer duct is too long, has too many elbows, or is simply too clogged with lint.
- The hose is crushed, constricted, or clogged with moisture and lint which is preventing proper airflow from the dryer.
- The vent cap located outside your home is clogged with lint. This means an accumulation of lint is backing up through the dryer vent and is collecting inside your dryer.
Troubleshooting Flow Sense Errors on Your LG Dryer
When the Flow Sense indicator begins to show a problem with or without the error codes d80, d90, or d95, it’s important to not only check your dryer vent, but completely clean it as well.
The cleaning process includes the vent beginning on the back of your machine, and goes all the way to the cap or hood vent outside your home.
You’ll want to be sure to check outside to see exactly how little or how much airflow there actually is.
When your home is equipped with a louvered vent cap, good airflow is signified by the flaps being nearly parallel to the ground below.
You’ll also want to remove the lint trap, and use a flashlight to see how much lint is stuck under. Lint that becomes stuck in your LG dryer’s lint trap can cause an increase in drying times.
This is because the lint acts as a plug, thus restricting proper airflow.
Troubleshooting Steps to Take for the Error Codes
- First, disconnect the dryer exhaust vent hose from the back of your dryer.
- Next, add a load of wet clothes to the dryer and begin a drying cycle.
- If your clothes dry within a normal timeframe, then your issue is definitely inside the exhaust system.
- If the clothes are still wet, the issue may be a bad thermal fuse or heating element.
LG Dryer Error Code d80
The error code d80 on your LG dryer means that there is an air blockage of 80%.
This means your dryer’s air exhaust is not pushing enough air out of your dryer through your home’s outdoor venting.
So, in other words, your dryer is 80% clogged either inside the air exhaust hose on the back of your dryer, inside the wall ducts, or the outdoor vent.
Here’s how to fix this issue:
- Check the lint filter to ensure it is clean and free of lint
- Disconnect the exhaust hose from the back of your unit and check if it’s blocked or clogged by lint.
- Check inside the wall duct for visible lint blockages
- Move outside your home, and check the outdoor vent to see if you see lint build up in there
Please note that some outdoor air vents are located on the side of your home, and may possibly even be on your roof.
LG Dryer Error Code d90
D90 is much like LG error code d80, except your system is more restricted.
The error code d90 displayed on your LG dryer means there is an air blockage of 90% in your system.
Basically, the air exhaust system attached to your dryer is not pushing an adequate supply of air through to the exterior exhaust system.
The d90 error code shows that your dryer is clogged by 90% between the air exhaust hose on the rear of your machine, inside wall ducts, or in the outdoor vent.
Here are the steps you should take:
- Check the lint filter to ensure it’s clean and free of lint debris
- Disconnect the exhaust hose from the back of your dryer and see if there is a build up of lint inside
- Disconnect the exhaust hose from the wall in your home and see if there is a build up of lint inside
- Move outdoors, and check the outdoor vent to see if there is a build of lint inside
If you find a build up of lint in one or more of these places, it’s imperative that it’s all removed. Do your best to not leave even a small amount of lint through this system.
LG Dryer Error Code d95
The error code d95 indicates your dryer’s exhaust system has an air blockage of 95%. This means the dryer is not pushing an adequate amount of air from the dryer through the venting system to outside.
The error code d95 basically means your dryer’s air flow is restricted by 95% somewhere inside the exhaust system.
The issue may be in the exhaust hose on the back of your dryer, inside your wall ducts, or even at the outdoor vent.
Here is how to check for a clog:
- Check your dryer’s lint trap to ensure it’s clean and free of lint
- Remove the exhaust hose from the back of your dryer and look for a blockage
- Remove the exhaust hose from the wall inside your home and look for a lint blockage
- Check the outdoor vent to ensure there’s build of lint inside
There’s no doubt you will find a build up of lint in one or more of these places. If so, be sure to use the proper brushes and tools to clear the blockage.
Once the blockage is cleared, the error message will go away and you’ll no longer be at risk of your home catching fire. Have you experienced any of these LG error codes? Where was your issue and what steps did you follow to fix it? Comment now, and let us know!
