Your LG LCG3011ST gas cooktop has a safety and design flaw. The plastic inserts that LG uses on the control knobs is a safety and fire hazard. The plastic inserts crack and break apart. After they crack and break a user has no idea what position the gas valve is. This is a safety and fire hazard. By the sheer number of bad reviews concerning the faulty knobs it is apparent LG does not intend to back its product until someone's home catches fire because of the condition is allowed to exist and someone gets hurt because of this safety condition that LG approves of.
