4 posts in this topic

I am looking for a service manual for this series 70 dryer trying to determine where an intermittent squeal is coming from.

A squealing noise in these dryers will almost always be from: 1) bad drum rollers or 2) bad idler pulley.  Best bet is to install the maintenance kit for this dryer, includes new drum rollers, idler pulley and belt.  Guts all the rolling components in one shot.  Click the pic below to git you one:

Thanks so much...so what should the motor feel like when I take the belt off and spin it while it's installed? If I'm going back in I want to know if it's stiff as well.

Motor pulley should spin silently and smoothly when you give it a flick.  There is a chance that the motor is the source of the noise but it's much less common than the drum rollers or idler.  Easy enough to tell, though, if you're going back out.  And take a maintenance kit with you-- even if you don't use it on this repair, you'll use it eventually on another job and probably soon.
