I have Sears Kenmore electric dryer I'm working on. It's 16 years old, but
it's been good to us and we're wanting to keep it for a while longer. The
shell, drum, heater, etc. is in good condition, but the seals were going out
and it was somewhat noisy.
I replaced the front and rear drum seals (they were in bad shape), lint
chute seals, belt and idler pully. The motor, blower wheel, and support
rollers seemed to be in good shape. In particular, the rollers seemed
smooth, no obvious wear on the shafts or wobble, so I cleaned and oiled them
and put them back in. The blower blades were all intact, no chips or
anything missing, so again I cleaned it and put it back. I blew the lint
out of the motor, the shaft seemed to turn smoothly, the bearings and belt
pully looked ok. I didn't see anywhere to oil it.
However, after putting it all back together, even though it's definately
smoother that it was, it's still noisy. I know it's hard to explain it on
the net, but it's similar in pattern to a car motor fast idling (not quite
as loud, though <G>). Since the pattern is fairly fast (much faster than
the drum rotation speed), I don't think it's something with the drum or
I don't have a problem with replacing some more parts, but I don't want to
replace anything else if I don't have to (especially the motor), but I'm not
sure what to try next: rollers, blower, or motor.
Any suggestions would be appreciated.
