If you own an LG dryer and suddenly see a d80 error flashing on the display, you’re not alone. This common error code is your dryer’s way of alerting you to a restricted airflow problem—and ignoring it could lead to longer drying times, overheating, or even permanent damage to your appliance.
At Express Repair, we specialize in diagnosing and fixing dryer issues fast—so let’s walk through what this error means, what you can do about it, and when to call in the pros.
The d80 error code indicates that your dryer is experiencing 80% airflow blockage in the venting system. While your dryer may still work, it’s operating under stress. This code helps prevent overheating and encourages you to fix the airflow before it causes more serious issues.
Several issues can trigger this error:
Lint buildup in the lint trap or filter
Clogged vent hose or wall duct
Crushed or kinked exhaust hose
Blocked external vent cap (often from debris, bird nests, or snow)
Too long or poorly designed vent system with too many turns
In short, anything that prevents air from escaping freely can result in the d80 error.
Here are a few steps you can take before calling in a technician:
Clean the lint filter thoroughly. Even if you clean it after every load, occasional deep cleaning is essential.
Inspect the vent hose. Disconnect it from the back of the dryer and check for lint clogs or obstructions.
Check the outdoor vent. Make sure it opens properly and isn’t blocked by leaves, snow, or animal nests.
Reduce sharp bends in the ductwork and shorten the hose if possible.
Run a test dry cycle after each fix to see if the error clears.
If the error persists even after these checks, it may be time to contact a professional.
Operating your dryer with restricted airflow can lead to:
Increased drying times
Overheating
Higher energy bills
Potential fire hazards
Premature wear on the heating element and motor
