Lg Dryer D90 Code Meaning
The LG Dryer D90 code signals a specific issue with your dryer. Understanding this code helps you identify problems early. This saves time and avoids bigger repairs.
The D90 code often relates to airflow or sensor problems. It stops the dryer from working properly until fixed. Knowing what causes this error and its signs is important.
Common Causes
One common cause is a clogged lint filter. This blocks air and triggers the error. Another cause is a dirty or faulty moisture sensor. It may send wrong signals to the dryer.
Blocked or kinked vent hoses also cause the D90 code. Poor airflow makes the dryer overheat or stop. Sometimes, electrical issues in the control board create this error.
Symptoms Of The Error
The dryer might stop mid-cycle with the D90 code showing. Clothes stay damp even after a full drying run. You may hear unusual noises from the dryer drum.
The dryer’s display panel may flash or lock up. It might not start at all if the error persists. These signs indicate a need for cleaning or repair to fix the issue.
Resetting The Dryer
Resetting your LG dryer is a simple way to fix many common issues, including the D90 error code. This process helps clear minor electronic glitches and refreshes the dryer’s system. Follow the steps below to reset your dryer safely and effectively.
Power Reset Steps
- Turn off the dryer using the power button.
- Unplug the dryer from the wall outlet or switch off the circuit breaker.
- Wait at least five minutes to let the control board fully discharge.
- Plug the dryer back in or turn the circuit breaker back on.
- Press the power button to turn the dryer on again.
Diagnostic Test Mode
- Turn the dryer off by pressing the power button.
- Plug the dryer back in or restore power at the circuit breaker.
- Press and hold the two specific buttons for your model (check your manual, often “Temp” and “Wrinkle Care”).
- While holding these buttons, press the “Start” button to begin the test cycle.
- The display may show “lnS” or a similar code during the test.
- When the test cycle finishes, the dryer should reset and clear error codes.
Manual Reset Procedure
- Turn off the dryer and unplug it from the power source.
- Locate the thermal fuse, usually behind a small plastic plate on the lower right side.
- Remove the plate carefully to access the reset button near the burner tube.
- Press the reset button until you hear a click.

Cleaning And Maintenance
Proper cleaning and maintenance keep your LG dryer running smoothly. Regular care prevents errors like the D90 code. It also extends the dryer’s life and boosts efficiency.
Focus on three key areas: the lint filter, moisture sensors, and exhaust vent. Each part needs attention to avoid common problems. Simple steps can save time and costly repairs.
Lint Filter Cleaning
Clean the lint filter before every drying cycle. Remove lint buildup to improve airflow and drying speed. Use your hand or a soft brush to clear the screen. Avoid water or harsh cleaners that can damage the filter. A clean filter reduces fire risk and energy use.
Moisture Sensor Care
The moisture sensors detect dryness and stop the dryer when clothes are dry. Over time, residue can cover these sensors. Wipe them gently with a soft cloth and mild detergent. Do this every few weeks to keep sensors accurate. Clean sensors help prevent over-drying and save energy.
Exhaust Vent Inspection
Check the exhaust vent for blockages every few months. Remove the vent hose and look for lint or debris inside. Use a vent brush to clean the duct from the dryer to the outside vent. Make sure the hose is not kinked or crushed. Clear vents improve drying times and prevent overheating.

Vent System Troubleshooting
Troubles with the vent system often cause the LG dryer D90 code to appear. This error signals airflow issues. Proper airflow is vital for drying clothes efficiently and safely. Checking and maintaining the vent system can solve many problems.
Blocked vents reduce dryer performance and increase fire risk. Vent system troubleshooting helps restore proper function. Follow simple steps to inspect and clean the vent parts.
Checking For Blockages
Start by examining the vent outlet outside your home. Look for lint buildup or debris covering the vent. Use a flashlight to see inside the vent hose for obstructions. Blockages stop air from moving freely. Remove any visible lint or debris carefully. Check the vent hose for bends or kinks that limit airflow. Straighten or replace damaged hoses to improve ventilation.
Cleaning Vent Hose And Duct
Detach the vent hose from the dryer and wall connection. Use a vacuum cleaner with a hose attachment to suck out lint inside. A long vent brush can help scrub the duct walls. Clean both ends thoroughly to ensure no lint remains. Reattach the hose securely to avoid air leaks. Regular cleaning prevents buildup that causes the D90 code.
Professional Vent Cleaning
Some vent ducts are hard to reach or heavily clogged. Professionals use specialized tools to clean deep inside the vents. They also inspect for damage or improper installation. Hiring experts ensures a thorough cleaning and reduces fire hazards. Schedule professional vent cleaning yearly for best dryer performance and safety.
Additional Fixes
Dealing with the LG Dryer D90 code often requires more than simple steps. Additional fixes target less obvious causes that can stop your dryer from working properly. These solutions help ensure your appliance runs safely and efficiently.
Thermal Fuse Reset
The thermal fuse protects your dryer from overheating. If it blows, the dryer may stop running or show an error code. Locate the fuse near the heating element or blower housing. Some models have a reset button on the fuse. Press it firmly until you hear a click. This can restore power to the dryer. If your model lacks a reset button, the fuse may need replacement. Always unplug the dryer before inspecting or resetting the fuse. Resetting the thermal fuse can clear errors and prevent future shutdowns.
Inspecting Dryer Components
Check all key parts for damage or wear. The drum belt might be broken or loose. The drum rollers can wear out and cause noise or drum issues. The heating element should be clean and intact. Sensors inside the dryer must be free from dirt and corrosion. Clean the moisture sensor bars with a soft cloth and mild soap. Inspect the vent hose for blockages or kinks. Proper airflow is critical for drying and safety. Replacing worn parts helps your dryer work smoothly and avoids error codes.

Preventing Future Errors
Preventing future errors like the LG dryer D90 code starts with good care and smart use. Small habits help keep your dryer running smoothly. Avoiding errors reduces repair costs and extends the dryer’s life.
Regular Maintenance Tips
Clean the lint filter before and after every load. This stops lint build-up and improves airflow.
Check the moisture sensor bars inside the drum. Wipe them gently with a soft cloth and mild soap.
Inspect the exhaust vent regularly. Remove any blockages and ensure the vent hose is straight and secure.
Use a vent brush to clean the entire vent system from the dryer to the outside vent. This prevents overheating and errors.
Proper Dryer Usage
Do not overload the dryer. Clothes need space to tumble freely for even drying.
Use the correct cycle for the type of fabric you are drying. This avoids unnecessary stress on the dryer.
Turn off the dryer and unplug it during storms or power surges. This protects the electronics inside.
Run the dryer only when home. This helps you stop the machine if an error or problem happens.
