No matter the make or model dryer you own, it needs periodic maintenance.
A dryer’s life expectancy has much to do with maintenance of the dryer itself and the dryer vent exhaust system. Dryer manufactures produce dryer maintenance kits. The kit contains drum rollers, belt, Idler pulley, some kits have one or more part depending on model/serial break.
Periodically inspecting and cleaning your dryer vent system will add to the life expectancy.
With a clogged dryer vent the hot air is not able to vent properly. Drum roller bearings have a tendency to fail due to overheat conditions inside the dryer cabinet.
Also prolonged temperature to all the moving parts will cause them to fail prematurely. It is recommended you inspect your vent run once a year, unless your vent run is prone to lint build up, these will need checked twice a year in most instances.
