The LG Dryer d80 Error Code Meaning

LG dryers come with smart sensors that make them intelligent appliances. These sensors can detect and diagnose various problems, which helps users troubleshoot issues effectively.

One diagnostic error is the d80 code, which describes potential blockages in the dryer’s exhaust system, vent, or wall duct. The “d” in the code signals a blockage, and the “80” indicates it’s approximately 80% blocked.

The most common triggers of the error code d80 are,

  1. Lint clogging in the exhaust duct: When lint builds up, the dryer displays the d80 error to remind you to clean it, which happens after drying clothes.
  2. Blocked outside vent hood: If things like leaves or nests obstruct the vent hood, the dryer can’t remove moisture properly, leading to the d80 error.
  3. Crushed or damaged air duct: A damaged duct slows airflow, making the dryer less effective and causing the d80 error.
  4. Poor ventilation design: If your ventilation system has a small duct or too many twists and turns, it’s challenging for the dryer to vent moist air, resulting in the d80 error. This suggests improving ventilation.
  5. Extra-long duct with many bends: A lengthy duct with numerous turns can delay drying and trigger the d80 error, indicating the need to change the duct for better dryer performance.

LG Dryer d80 Error Code but with No Blockage [Explained]

Usually, a blockage is the primary cause of the d80 error code. However, there are instances when no obvious blockage is present. In such cases, consider these alternative reasons:

1. Broken Sensor

The d80 error might occur because the moisture and temperature sensors in the dryer may not be working.

These sensors measure how wet your clothes are and how hot it is inside the dryer.

When they’re gone rogue, they give wrong information, making the dryer think there’s a vent problem, even if there isn’t.

To fix this,

Check the Sensor: Check if the sensors are working correctly. You need to look inside the dryer and the control panel. Use a thermometer to measure the dryer’s temperature and telly it with the sensor reading.

Replace the Sensor: If you find the sensors are not working right, you should replace them. You can usually get replacement sensors that match your LG dryer from appliance stores or authorized service providers. Make sure to get the right sensor for your dryer model.

Get Professional Help: If you’re uncomfortable replacing the sensor yourself or your dryer is still under warranty, it’s best to contact LG customer support or a certified technician.

2. Excessive Laundry Load

Overloading the dryer with a big laundry load can strain its system. When the dryer is packed, it has to work extra hard to dry everything properly.

This added stress on the dryer’s parts can slow the drying process and make it think there’s a vent issue, even when there isn’t.

To fix this,

Reduce Laundry Load: Begin by putting less laundry in the dryer. Check your dryer’s user manual for the manufacturer’s recommended load capacity.

Load Clothes Evenly: Don’t pack the dryer too tightly. Arrange the clothes so there’s room for air to move around. This helps with better drying.

Use Sensor Drying: If your dryer has a sensor drying feature, use it. This technology senses how wet the clothes are and adjusts the drying time. It prevents over-drying and helps save energy.

3. Malfunctioning Control Board

The control board is like the brain of the dryer. It manages temperature settings, timing, and sensor information. When it’s not working right, its malfunctioning can lead to the d80 error, even if there’s no vent issue.

To fix this,

Check the Control Board: First, look at the control board for any visible damage or burn marks. This can show if there’s a clear problem with it.

Test the Control Board: If there’s no obvious damage, you can run tests to check if the control board works correctly. How to do this can depend on your dryer model, so look in the user manual for guidance.

Replace the Control Board: If it is not working, you should replace it. You can usually buy a new control board that matches your dryer model from authorized service providers or appliance parts stores.

Get Professional Help: If you’re unsure about testing or replacing the control board yourself or if your dryer is still under warranty, it’s a good idea to call LG customer support or a certified technician for help.

4. Dirty Lint Filter

The lint filter in your dryer affects how air flows through the machine. When it’s clogged with lint and debris, it blocks the airflow.

This blockage makes drying less efficient and can lead to the dryer showing the d80 error code.

The error happens because the dryer thinks there’s a vent problem due to poor airflow, even though the vent itself is clear.

To fix this,

Regular Lint Filter Cleaning: Get into the habit of cleaning the lint filter before or after every drying cycle. Remove it from the dryer and use your hand or a lint brush to clear away the lint.

Thorough Cleaning: Sometimes, giving the lint filter a deeper cleaning is a good idea. You can wash it with warm, soapy water and let it dry completely before putting it back in the dryer. This helps get rid of any residue from fabric softeners or dryer sheets.

Check for Damage: Look at the lint filter for any damage or wear. If it’s damaged, consider replacing it to keep the dryer working efficiently.

5. Faulty Heating Element

The heating element in a dryer is what makes the warm air that dries your laundry. It can’t provide consistent and efficient heating when it doesn’t work well or its terminals get damaged.

As a result, it takes longer to dry clothes, and this extended drying time can make the dryer mistakenly think there’s a vent problem, triggering the d80 error.

To fix this,

Test Continuity: Start by checking the heating element’s continuity using a multimeter to see if the heating element can carry an electrical current. If it fails this test, it’s a sign of a problem.

Replace the Heating Element: If the heating element doesn’t pass the continuity test or if you can see visible damage, it’s a good idea to replace it.

Get Professional Help: If you’re unsure how to do the continuity test, replace the heating element, or if your dryer is still under warranty, contact LG customer support or a certified technician for help.

6. Electrical Issues

Electrical problems, like damaged wiring, short circuits, or loose connections, can disrupt communication between different dryer parts.

These parts include sensors, control boards, and heating elements. When the electrical system has issues, it can cause incorrect readings and error codes.

To fix this,

Inspect the Wiring: Look at the wiring and electrical connections inside the dryer. Check for any signs of damage, fraying, or loose connections.

Repair or Replace: If you find damaged wiring or loose connections, fix or replace the parts causing the problem. Make sure the connections are secure and well-insulated to prevent more issues.

Get Professional Help: If you’re uncomfortable working with electrical components or the problem is complex, it’s best to call a certified technician or the manufacturer’s customer support for professional help.

7. Blown Fuse

When a fuse blows, it interrupts the power supply to the dryer, keeping it safe from electric surges and further damage.

However, when a fuse blows, it also disrupts this circuit, causing a loss of power to these important components.

To fix this,

See what has blown the Fuse: Before replacing the fuse, check for any short circuits, electric surges, or water damage.

Check the Fuse: Once the problem is sorted, check the dryer’s fuse to see if it’s blown. You can usually find the fuse in the dryer’s electrical panel or control area. Your dryer’s user manual will help you locate it.

Replace the Fuse: If the fuse is blown, replace it with a new one with the same amperage rating. You can often get replacement fuses from hardware stores or authorized service providers.

Get Professional Help: If you’re not comfortable working with electrical components or if the problem is complicated, it’s best to contact a certified technician or the manufacturer’s customer support for professional help.

8. Tripped Breaker

Like a fuse, a tripped circuit breaker stops the electrical power to the dryer. Circuit breakers protect electrical circuits from overloads or short circuits.

When a circuit gets overloaded or experiences a short circuit, the breaker trips, cutting off power to that circuit, including the one powering the dryer.

To fix this,

See what has tripped the Breaker: Before resting the breaker, check for any short circuits, electric surges, or water damage.

Check the Breaker: Look at your circuit breaker panel to see if the breaker supplying power to the dryer has tripped.

A tripped breaker will be in the “off” position, usually moved away from the “on” position.

Reset the Breaker: If you see that the breaker has tripped, reset it by moving it to the “on” position. Reset it firmly because a loose connection can lead to more trips.

9. Lack of Gas Supply

When there’s no gas supply, the gas burner inside the dryer can’t work, making drying less effective.

Without heat, drying takes longer, which can trigger the d80 error code. The dryer thinks there’s a vent problem because it’s taking too long to dry.

To fix this,

Check the Gas Supply: First, ensure the gas supply to the dryer is connected and working correctly. Confirm that the gas line is open. If your dryer uses propane, check that the propane tank is not empty.

Inspect for Blockages: If there’s gas in the supply line, but it’s not reaching the dryer, look for blockages or obstructions in the gas line. This might involve checking the gas line, fittings, and shut-off valves for potential issues.

The Flow Sense Warning and LG Dryer d80 Code: A Safety Feature

Dryers can sometimes cause home fires in the U.S., so dryer makers add safety features to prevent this.

One is the Flow Sense Warning, which looks for things like too much lint that could start a fire.

When the sensors in your dryer notice a sudden increase in heat, it stops working and show an error code, like d80 or d90.

If you ever see one of these error codes, it’s important to turn off your dryer and find out what’s causing it.

It could be things like lint blocking the vent, a bent or broken exhaust pipe, or even a vent not set up properly.

By fixing these problems, you keep your dryer safe and reduce the fire risk.
