How to Reset a LG Dryer
Power-cycle for 60 seconds after clearing the duct restriction.
Reset Steps
- 1
Unplug the dryer (or breaker off) for 60 seconds.
- 2
Restore power and run Time Dry — the airflow test re-runs and the D-code clears if the duct is actually clear.
- 3
If D80/D90 returns after a full duct cleaning, check the exterior vent flap for paint, screening, or nesting blockage.
💡 Good to know: There is no code-bypass: LG D-codes return until airflow is physically restored.
If the Code Comes Back
A code that returns after a reset means the underlying fault is still present. Look up your exact code for its causes and step-by-step fix:
D80 Duct blockage detected — exhaust duct 80% blocked D90 Duct blockage detected — exhaust duct 90% blocked D95 Duct blockage detected — exhaust duct 95% blocked F9 Thermistor failure — temperature sensor not reading CL Child lock is active — controls are locked nP No power to the heating element HS Humidity sensor error — moisture sensing failure GAS Gas supply error — no gas detected (gas dryer models only)
Frequently Asked Questions
Can I keep using my LG dryer with a D80 code? +
It will run, but with 80% duct blockage drying is slow and the thermal cutoff can trip — and a restricted duct full of lint is a fire risk. Clean the vent run before continuing to use it.
