LG Tumble Dryer Error Code FO
If your LG dryer displays error code FO, it usually indicates that the appliance has detected a problem with the lint filter.
LG dryers are designed to prevent operation if the lint filter is not correctly installed. The lint filter helps maintain proper airflow and prevents lint from entering the dryer vent system. If the dryer cannot detect the filter in the correct position, it may stop the cycle and display the FO error code.
