LG Dryer d80 Error: Check the Exhaust Path

Documentation checkedBy ErrHiveUpdated October 28, 2026

THE SHORT ANSWER

The dryer reports restricted exhaust airflow.

d80 is an exhaust-airflow warning on covered LG vented dryers. Start with the lint filter and accessible duct. A clean filter does not rule out a restriction farther along the vent.

First safe check

Stop the dryer and check the lint filter.

Applies to

LG vented dryers with Flow Sense; not a universal heat-pump dryer code.

Before you start

Do not keep operating a dryer with restricted exhaust. Avoid moving a gas dryer or disturbing its supply connection.

Use the checkboxes to keep track as you read. Stop at any warning or step that does not match your appliance.

Check the filter
Remove lint; reinstall the clean, dry filter.

Hidden or inaccessible restrictions need professional cleaning.

THE DETAILS MATTER

Scope & troubleshooting notes

Gas-dryer exception

LG notes that d80 can also involve missing gas supply on a gas dryer. Have the installer or qualified technician assess that condition; do not open gas components.

YOUR NEXT DECISION

When to stop and get help

Arrange vent cleaning or service if accessible checks do not resolve the warning.

Record what you see

Keep the full model number, exact displayed code, and your observations together for the next conversation.
