LG dryer making noise — squealing, thumping, grinding

Squealing from an LG dryer is usually the idler pulley or worn drum glides. A rhythmic thump comes from flat-spotted drum rollers or a damaged belt. Grinding or scraping often means a coin or object in the blower or a worn drum seal. Most of these repairs cost $180 to $350.
