On a supported LG dryer, d75, d80, d90 or d95 means Flow Sense detected approximately 75%, 80%, 90% or 95% exhaust restriction. Stop using high heat, clean the lint screen and check the exterior hood for strong airflow. Then inspect the accessible duct for crushing, excessive length or lint and arrange professional vent cleaning when needed.

Exact questions
Common questions about “LG dryer d75, d80, d90 or d95 code”
What does d75, d80, d90 or d95 mean on a LG dryer?+
It means Flow Sense detected approximately 75%, 80%, 90% or 95% exhaust restriction.
Can I clear d75, d80, d90 or d95 by resetting the dryer?+
A restart may clear a stored display only after the underlying condition is corrected. Repeatedly resetting without correcting the cause is not a repair.
Can I keep drying while d75 shows?+
Use a low-heat or air cycle and smaller loads until the vent has been cleaned, since a restricted vent traps heat and lint. A d90 or d95 reading means airflow is badly reduced, so stop using the dryer until the vent is cleaned.
What should I clean first?+
Clean the lint filter, then the vent hose and outside hood. Check for crushed or overlong ducting.
When is a code a real dryer fault?+
If it persists after the vent is cleaned and confirmed clear, call service.
Does d75 mean the dryer is failing?+
No. The number is an estimate of how restricted the exhaust is, not a failure. A low reading means airflow is only slightly reduced, but it still tells you the vent needs cleaning soon.
How often should the vent be cleaned?+
At least once a year, or more often with heavy use, long duct runs or pets. A dryer vent that is clean lets clothes dry faster and lowers the fire risk from lint build-up.
Can a long or bent vent run cause d75 even when it is clean?+
Yes. Flow Sense measures how freely air leaves the dryer, so a vent that is very long, has many elbows or is squashed behind the machine can read as restricted even with no lint in it. Shorten or straighten the run if you can.
Will the code clear once I clean the vent?+
It should drop on the next cycle, because the dryer measures the airflow again each time it runs. If the reading stays high after the vent is clean and clear, the cause is elsewhere and the dryer needs a service visit.
