Most of us immediately think of the idler when a dryer starts squeaking and howling, right?  Maybe the drum rollers as a second.  I have one with a squealing motor.  Of course it was quiet as a mouse once everything was pulled out of the cabinet.  Under side load (as it is when the pulley is tensioned by the belt, the squealing is very loud.

 

Too bad this noise is coming from the motor.  The bearings are fine.  Inside the motor toward the front of the motor frame you can see a centrifugual cutout mechanism with springs, weights and a switch that rides on a large plastic ring.  After years of operation, the plastic switch arm polishes up the plastic ring and starts squealing.  Adding a little grease to the plastic ring is a waste of time. 

 

This problem is really a waste of an otherwise good motor.  You can actually pull out the connection block and have a good look at the culprits.  Can't think of a clever fix at the moment, but thought I'd make a note of it.  When hunting for a squealing part on these dryers - they are pretty good dryers -  pull the motor pulley hard to one side and rotate it to find this noise.

 

Unfortunately, the blower fan on an older unit will probably refuse to unscrew, so it is time to chisel off the old one and get a new blower fan too.  But, that's what they pay me the big bucks for, right?

Instead of a chisel, I use a 1" hole saw. 10 seconds to have blower off:)

Medium sized ball-peen hammer and about 5-10 seconds is all it takes to smash the blower wheel off around the center hub area.

This my preferred method. Elegant, quiet, quick.
