I have a 20 year old Kenmore electric dryer (essentially a Whirlpool). It's
held up pretty good overall. About 4 years ago the motor wouldn't turn, so
I replaced the motor along with the rollers, belt, and front and back
bearings. Everything has been working fine since then (it was running
quieter than when it was new!).
About 2 weeks ago we started getting an intermittent rumble/heavy vibration
about every 10 seconds or so. It would only last a few seconds, but it
would really shake the dryer. Sometimes it's worse than others.
I figured one of the rollers was loose or worn and I took it apart to check
it. However, I'm not seeing anything that seems like it's out of alignment.
The front and back bearings seem OK and I don't see any play in the back
support rollers. The fan wasn't replaced 4 years ago; it's still the
original one, but it doesn't seem loose or have any damage on the blades
except a few tiny nicks and scratches.
I've done some searching using words like "electric dryer rumble", but most
of the hits seem to point to worn out bearings, rollers, or blower wheel,
and as I said those are all in good shape and/or fairly new. I may go ahead
and replace the fan; it's about the only original moving part on the dryer.
A dryer is such a simple item, but I don't really want to have to scrap it
if it's something fairly easy (and inexpensive) to replace.
Any suggestions would be appreciated.
