vent duct
Search by your model number so the part matches.
LG says d80, d90 and d95 (Flow Sense) mean airflow is restricted somewhere between the dryer and the outside. The number is roughly how blocked the vent is: 80, 90 or 95 percent. Also shown as d90, d95 on some models.
I am Ramez, owner of R3M Appliance Repair in Rockwall, TX. Below is what this code means, what you can safely try before calling anyone, and the point where it is time to call. If you are in the Rockwall area and want it handled today: (469) 446-4242.
Most common first. In my experience the first one or two on this list account for most LG d80 calls.
Safe things a homeowner can do. Unplug the dryer before reaching into anything.
The code keeps coming back after the visible duct and hood are clean, which usually means the blockage is inside the wall run. At that point the fix is usually a part, and guessing at parts gets expensive fast. I test first, then quote, so you only pay for what is actually broken.
If the steps above did not clear it, one of these is the usual culprit. Always match the part to your full model number (on the sticker inside the door or on the back).

Fix the cause first, then unplug the dryer (or turn it off at the breaker) for about a minute and restart. The code clears once the dryer no longer sees the problem. If it comes right back, the cause is still there.
Yes. LG uses different displays on different model years, so the same problem shows up as d80 on some machines and d90 or d95 on others. The fix is the same.
Usually yes. Vent duct and similar parts cost a fraction of a new dryer. I tell you the price before any work starts, and if a repair is not worth it I say so.
Most days, yes. I carry common LG parts on the truck, so many d80 repairs are done in one visit. Call or text (469) 446-4242 with your model number.
