Have had our LG dryer for about 6 months and the biggest issue is that clothes do not come out totally dry.  The sensor drying is the real problem where most of the clothes are dried but the heavier garments (jeans, towels, etc.) that are in with that load are not dry.  Sensor dry is the default.  There are a great number of setting combinations so maybe we just need to figure out which is best.  I usually turn to manual dry and a standard load is dry with the hour setting.
