What is the D80 Error Code on LG Dryers?

First things first, let’s understand what the D80 error code means.

Here’s a simple breakdown:

  • D stands for clogging or blockage.
  • 80 indicates an 80% blockage.

So when you see the D80 error, it’s telling you that there’s an 80% blockage in the vent, duct, or exhaust of your LG dryer.

This can happen due to several reasons, such as:

  • Lint buildup in the exhaust
  • A crushed or damaged air duct
  • Lengthy or bent ducts that restrict airflow

LG Dryer D80 No Blockage: Issues and Fixes

Now, here’s where things get tricky. Sometimes, you might see the D80 error even when there’s no actual blockage. This is known as the “D80 No Blockage” error. It can be triggered by various factors, such as:

Issue Fix
Smaller load size Expand the load size to ¾ full
Dirty lint filters Clean out the filters
Burnt heating element Replace the heating element if it shows no continuity on a multimeter
Blown thermal fuse Replace the thermal fuse
Tripped breaker Reset the breaker if it’s tripped
Lack of gas supply Ensure adequate gas supply and check for leaks (gas dryers only)

Let’s go through each of these issues and their solutions in more detail.

1. Smaller Load Size

LG dryers have highly sensitive sensors that can sometimes misinterpret a small load as a fire hazard, triggering the D80 error. To fix this:

  • Load enough clothes to fill the dryer ¾ full. This will ensure the sensors can accurately detect the load.
  • Avoid overloading, as this can leave clothes damp.

2. Dirty Lint Filters

Lint filters trap lint during the drying process. If they get clogged, drying times can increase, which the dryer may interpret as a fire risk. Here’s how to clean your lint filters:

  • Remove the lint filter and scrub it with a soft brush and warm, soapy water.
  • Rinse thoroughly and allow it to dry completely before reinserting.
  • Clean the lint filter after every drying cycle to prevent buildup.

3. Faulty Heating Element

The heating element is crucial for drying clothes. If it malfunctions, clothes may stay damp and drying times will increase, potentially triggering a D80 error. To check and replace the heating element:

  1. Unplug the dryer and locate the heating element (consult your manual if needed).
  2. Use a multimeter to test the heating element for continuity.
  3. If there’s no continuity, replace the heating element.

4. Blown Thermal Fuse

The thermal fuse is a safety device that protects your dryer from overheating. If it blows, the dryer will shut off and may display the D80 error. Here’s how to replace it:

  1. Unplug the dryer and locate the thermal fuse (refer to your manual).
  2. Test the fuse with a multimeter. If there’s no continuity, it needs replacing.
  3. Install a new thermal fuse and reassemble the dryer.

5. Tripped Breaker

A power overload can trip the circuit breaker, which the dryer’s sensors may misinterpret as a D80 error. To fix a tripped breaker:

  • Locate your home’s main electrical panel and find the switch for your dryer.
  • If it’s in the “Off” position, flip it back to “On”.
  • If the breaker trips again, there may be an electrical issue that needs professional attention.

6. Lack of Gas Supply (Gas Dryers Only)

For gas dryers, insufficient gas supply can trigger the D80 error. To troubleshoot:

  • Check that the gas valve is fully open and the supply line isn’t kinked.
  • If you smell gas, shut off the gas immediately and call your gas company or a professional.
  • Have a technician inspect your dryer’s gas components for proper function.

How Does the D80 No Blockage Error Occur?

The D80 No Blockage error can also be triggered by temperature changes detected by the dryer’s flow or heat sensors. LG dryers have two types of sensors:

  1. Safety thermostats
  2. High-temperature thermostats

These sensors are programmed to reach certain temperatures within a specific time frame. If they detect excessive heat, even without an actual blockage, they may trigger the D80 error. To prevent this, it’s important to identify and address the source of excess heat.

Flow Sense Warning

The Flow Sense Warning is a helpful feature in LG dryers that alerts you to potential fire hazards. When the flow sense sensors detect an unusual rise in the heating algorithm, they may display the D80 or D90 error codes. If you see these warnings, power off your dryer immediately and check for:

  • Lint blockages
  • A damaged exhaust pipe
  • Clogged lint filters
  • Excessively long or convoluted ductwork

Addressing these issues can help prevent dangerous situations and keep your dryer running smoothly.

LG Dryer D80 Code Troubleshooting

If you’ve checked for blockages and addressed potential issues but are still seeing the D80 error, try the following troubleshooting steps:

  1. Turn on your LG dryer.
  2. Press and hold the “Time Dry” and “Signal” buttons simultaneously for 3 seconds.
  3. When you see “Off” on the display, the troubleshooting is complete.

Note that the exact button combination may vary by model, so consult your user manual for specific instructions.

Some alternate button combos include:

  • Turbo Steam (Control Lock) + Less Time
  • Energy Saver + Less Time
  • Time Dry + Wrinkle Care
  • Wrinkle Care + Energy Saver

LG Dryer D80 Reset

If troubleshooting doesn’t resolve the D80 error, you may need to reset your dryer:

  1. Turn off the dryer and unplug it from the wall outlet.
  2. Flip the circuit breaker for the dryer to the “Off” position.
  3. Press and hold the Power and Start buttons together for 5 seconds.
  4. Plug the dryer back in and switch the circuit breaker to “On”.
  5. Press the Power button to restart your dryer.

If the error persists after resetting, it’s time to call in a professional appliance repair technician for a thorough diagnosis and repair.

Frequently Asked Questions

  • Q1: Why does my LG dryer keep saying “Flow Sense”?

If your LG dryer repeatedly displays the Flow Sense warning, it usually indicates a lint blockage in the air filter or ductwork. Turn off the dryer and thoroughly clean out any lint buildup to resolve the issue.

  • Q2: How do I fix the D80 error code?

To fix the D80 error, first check for and clear any blockages in the ductwork or exhaust vents. If the error persists, try resetting your dryer as described earlier. If the problem continues, call a professional for service.

  • Q3: How can I reset the Flow Sense warning?

To reset the Flow Sense warning:

  1. Turn off your LG dryer.
  2. Press and hold the Start button for about 5 seconds.
