Your LG dryer is flashing a code — here's what it's telling you, whether you can fix it yourself, and when to call an OKC dryer specialist. Codes can vary by model year, so confirm against your manual.
Vent blockage warning — 80%, 90%, or 95% of the vent is obstructed.
Likely cause: A clogged or restricted dryer vent. This is an airflow warning, not a parts failure.
What to do: This is your dryer telling you to clean the vent. A full-run cleaning clears it — exactly what we do.
Thermistor (temperature sensor) error.
Likely cause: A failed temperature sensor or wiring problem.
What to do: The sensor needs testing and replacement by a technician.
Child Lock is on — not a fault.
Likely cause: Child lock was enabled, so the controls are locked.
What to do: Hold the Child Lock button for 3 seconds to turn it off. No service needed.
Power failure during a cycle.
Likely cause: The power was interrupted mid-cycle.
What to do: Restart the cycle. If it recurs without power outages, have the board checked.
Auto-restart / communication error.
Likely cause: Internal communication fault between control boards.
What to do: Needs a technician to diagnose the boards.
