Hotpoint HTX24GASKWS 6.2 cu ft Gas Dryer with Auto Dry and Wrinkle Prevent Option MECH-04 Error Fix: Loud Thumping, Squealing, or Scraping Noise

Error code MECH-04 on the Hotpoint HTX24GASKWS 6.2 cu ft Gas Dryer with Auto Dry and Wrinkle Prevent Option means: Loud Thumping, Squealing, or Scraping Noise. The dryer makes a repetitive thumping, squealing, or rhythmic scraping noise during operation — worn drum support rollers are the most common cause; the rollers (small wheels on axle shafts) support the rear of the drum and develop flat spots when the dryer sits idle for extended periods; replace all drum rollers at the same time (typically 2 or 4 depending on model); a high-pitched squealing or chirping noise usually indicates a dry or worn idler pulley bearing — the pulley is spring-loaded and presses the belt tight; a scraping noise indicates the drum glides or slides (felt or nylon pads at the front of the drum) are worn through, allowing the drum to scrape against the front bulkhead; NEVER apply lubricant to drum rollers as it attracts lint (a fire hazard)
