LG Dryer Error Codes: Complete Troubleshooting Reference

LG dryer error codes fall into two main families: duct blockage warnings (D80, D90, D95) and component faults (TE1, 9A5). The D-series codes are caused by lint-clogged exhaust ducts and clear automatically after thorough cleaning. TE1 points to a failed exhaust thermistor that needs replacement. CL is a maintenance reminder, not a fault. 9A5 signals a power supply abnormality and typically affects gas models.

About These Lg Dryer Error Codes

LG dryers display error codes on the digital panel to identify faults ranging from clogged duct warnings to sensor and power failures.

Common Causes

  • Lint-clogged exhaust duct (D80/D90/D95)
  • Exhaust duct run too long or crushed flexible duct
  • Failed exhaust thermistor (TE1)
  • Corroded thermistor connector or broken wire harness (TE1)
  • Power supply abnormality at outlet or circuit (9A5)
  • Dirty lint filter triggering CL reminder

Symptoms You May Notice

Frequently Asked Questions

What does the D80 code mean on an LG dryer?
D80 means LG's Flow Sense system has detected that your exhaust duct airflow is restricted by 80%. The dryer will still run but heating efficiency drops. Clean the exhaust duct from the dryer to the exterior wall vent to clear it.
Will an LG dryer reset clear a D80, D90, or D95 code?
No. These codes are generated by airflow sensors and will return immediately if the duct is still blocked. You must clean the exhaust duct thoroughly. The code clears automatically after the next successful cycle once airflow is restored.
How do I enter LG dryer diagnostic mode?
Press and hold the Temp and Time Dry buttons simultaneously for 3 seconds. The display will show t01, t02, etc. Press Start to advance through each sensor test. Press Power to exit diagnostic mode.
Is TE1 dangerous on an LG dryer?
TE1 means the dryer cannot monitor exhaust temperature safely. It should not be used until the thermistor is replaced, since the dryer has no way to prevent overheating.
