Noises could be coming from many places in the dryer. I
will explain where most noise usually come from.
We will start with the drum support rollers. The
dryer uses two rollers to support the rear end or the
drum. These rollers have a metal sleeve
in the center, a plastic ream and the rest of the roller
is made of rubber. When a roller bearing
(the metal sleeve in the center)
grease dry out, the metal sleeve will wear out and the
roller will start making clanking noises.
The Idler pulley is the part use to apply tension
to the belt. The older type of idler pulley had a wheel
that the belt ride on, that eliminate the friction ob
the belt. They change the idler pulley,
the newer didn't use a wheel, it use a teflon glide.
This idler pulley with the teflon glide cause a lot of
friction on the belt When ever I replace
the belt I also replace the idler pulley with the one
with the wheel on it The blower wheel
is use to circulate air from the outside through the
inside of the dryer and to the outside using an exhaust
hose Most of the times when the blower
gets noisy it is because some object has fallen through
the filter housing and wound up on top of the blower
wheel Other parts that can cause the
dryer to run noisy are, loose cabinet, loose panels, the
motor, the belt, overloading the dryer, etc.
The best way to learn how to take the dryer apart and
check the mentioned parts is by seeing how it is done
