Less than year of use this dryer, keep constantly failing airflow sensor error code shows d80 or d90. Cleaned every corner, inside machine, including house duct systems, nothing works. I loved LG machines are reliable and last longer. I am not happy with technology advances it keeps failing the machine performance.  According to LG’s quote “Life is good”, it is great, but my life is very miserable with broken or malfunctioned dyer at the house. Life is not so good! Before you buy the dryer, please don't get excited about advanced technologies, instead do your research and find reliable one that doesn't fail.
