d80, d90, and d95 on an LG dryer are not a broken dryer — they're the dryer telling you the exhaust duct is badly restricted: 80%, 90%, or 95% blocked. LG built this warning in on purpose, because a clogged dryer vent is the #1 cause of dryer fires. The dryer is fine; the vent line running to the outside of your house needs to be cleared. Here's what it means and how to handle it.
Lint builds up over months and years inside the flexible duct behind the dryer and the rigid vent line running through the wall to the outside. As it narrows, airflow drops and the dryer throws d80 → d90 → d95 as it gets worse.
Check it: Clean the lint trap every load, then check and clear the flexible duct behind the dryer. The full vent run to the exterior usually needs a proper cleaning — this is our dryer-vent cleaning service, and it clears the code and removes the fire risk.
The flexible duct behind the dryer gets crushed when the dryer is pushed back against the wall, choking airflow even if the rest of the run is clean.
Check it: Pull the dryer out a few inches and make sure the duct behind it isn't crushed flat or kinked. Give it room.
The vent hood on the outside of the house can get clogged with lint, or its flap can stick shut or get blocked by a bird nest, trapping the air.
Check it: Go outside, find the dryer vent hood, and check that the flap opens freely and isn't packed with lint or debris.
A very long run with lots of elbows, or an undersized/ribbed line, restricts airflow enough to trigger the code even when reasonably clean.
Check it: If the code keeps returning after cleaning, the vent routing itself may need improving — a tech can assess and reroute or upgrade the line.
This is a vent-cleaning job, not a dryer repair — the dryer is working correctly by warning you. A professional dryer-vent cleaning clears the code, restores drying speed, and removes the fire risk. We do this as a dedicated service; ask about it when you book.

It's a warning that your dryer vent is 80–95% blocked, which is a genuine fire risk — clogged vents are the leading cause of dryer fires. It also means clothes take forever to dry. Clear the vent promptly, especially at d90 or d95.
The code clears once the exhaust vent is cleaned. Clean the lint trap, pull the dryer out and check the duct behind it, check the exterior vent flap, and have the full vent run professionally cleaned. It's not a part failure — it's airflow.
You can start by cleaning the lint trap and checking the duct behind the dryer, but the full vent run to the outside usually needs a professional cleaning to fully clear d90/d95 and remove the fire hazard. That's exactly what our dryer-vent cleaning covers.
