LG Dryer Flow Sense – What It Is And How It Works?

The market for clothes dryers is very competitive. So, manufacturers tend to highlight different features to stand out from their competitors, like LG and its Flow Sense dryer feature. But is Flow Sense just hype, or is it a feature that offers value?

Flow Sense on LG dryers is a crucial safety feature that monitors the dryer vent for any airflow restrictions. That feature enables your dryer to warn you if the ducting is clogging up, so you can clean your dryer vent in time.

Keep reading to discover what Flow Sense is, how it works, and how you can troubleshoot it when its indicator turns on.

Flow Sense is a safety feature that you can find on LG dryers. It helps monitor the dryer vent and ensure that there’s no blockage. Doing so enables you to keep your dryer running efficiently and prevent fires.

LG’s Flow Sense works by monitoring the dryer vent for any restrictions in airflow. Typically, problems in that area happen because of lint buildups and pinched or kinked ducting.

Whatever the case might be, restricted airflow is very dangerous for a dryer. So when your LG dryer’s Flow Sense detects that exhaust air isn’t moving as fast as it should, it will trigger a warning to let you know that there’s an issue.

Then, you can intervene by cleaning or adjusting your dryer exhaust vent to restore proper airflow. You will also clear the Flow Sense error code and indicator as you do that.

You can find the Flow Sense indicator on your LG dryer’s display panel. The indicator has the words ‘Flow Sense’ printed underneath an icon of a box with four horizontal lines.

When your dryer exhaust works without any problems, the Flow Sense indicator will not light up, and none of the Flow Sense error codes will appear. 

However, when the dryer senses a problem with its vent, it’ll illuminate the Flow Sense. The appliance will also show an error code that tells you how severe the problem is.

LG dryers with Flow Sense will also display error codes related to how bad the vent blockage is. Here are the LG dryer error codes associated with Flow Sense and what they mean.

• No error code: There are no airflow restrictions in the dryer vent.
• D80: A blockage is restricting airflow by 80% to 90%. The dryer will still work, but less efficiently, so your clothes might take longer to dry.
• D90: Something is restricting airflow by 90%. The dryer will automatically enter a cool-down mode and then stop working. That happens to protect the dryer from damage and prevent fires.
• D95: The dryer’s airflow is restricted by 95% or more. This level of airflow restriction is a severe fire hazard, so the dryer will also enter cool down mode and stop working.

When the Flow Sense indicator lights up and any of the error codes above appear on display, that means your dryer is not venting correctly. You should resolve the problem as soon as possible to prevent fires and allow your dryer to work efficiently again.

After you’ve removed the blockage in your dryer ducting, the Flow Sense error code should clear by itself. However, you can also clear the code by resetting the dryer following these steps:

• Firstly, disconnect the dryer’s plug from the wall socket.
• Next, leave the dryer alone for five minutes.
• Lastly, reconnect the dryer to its power supply.

Following these steps will also clear the dryer’s memory and the error code. As long as there are no airflow restrictions in the dryer’s vent, the Flow Sense indicator should not light up, and the code won’t return.

When the Flow Sense indicator turns on and a related error code is displayed, that means the dryer is not venting correctly. A lack of venting causes problems for the dryer and your household.

Firstly, restricted airflow through the dryer vent causes the appliance to work much longer than usual to dry your clothes. Not only will that waste your time, but it’ll also use a lot more energy to dry a standard load.

Secondly, when hot air can’t escape through the vent, the dryer and its vent will eventually overheat. That can cause the dryer to malfunction and pose a severe fire risk to your home. 

Remember: a buildup of lint and dirt clogging the vent can ignite very quickly, which is why dryer fires cause damage, injuries, and death in the US every year.
