What is the lifespan of an LG dryer?

The lifespan of an LG dryer is 10 to 13 years on average for both electric and gas models under typical household conditions, which is at or slightly above the industry average of 10 to 12 years for vented dryers. Electric models like the DLEX4000W, DLEX4200W, and DLEX5500W often last toward the higher end of that range at 11 to 13 years because they have fewer combustion components and less thermal stress on gas valves and igniters. Gas models like the DLGX4001W average 10 to 12 years but require earlier replacement of igniters, flame sensors, and gas valve coils around year 8 to 10. LG's newer dual inverter heat pump dryers may last even longer, up to 13 to 15 years, because they recycle hot air at lower temperatures and experience less component stress. Lifespan depends heavily on maintenance: the single biggest factor is venting quality, where a long, kinked, or foil-type vent that is never cleaned causes overheating, thermal fuse failure, heating element burnout, and control board damage, cutting life by 3 to 5 years. Cleaning the lint filter before every load, vacuuming the lint housing every 3 months, having the full rigid metal vent duct professionally cleaned annually, avoiding overloading beyond 75 percent full, and ensuring the dryer is level to prevent drum wobble can extend life significantly. The stainless steel drum rarely fails.
