I first looked at your website and it said a squealing noise could be coming from the drum wheels so I ordered those, a new belt and a new idler pulley. Thanks to the repair videos I changed those parts, but noticed the squeal was still there. The next choice was a new motor so I ordered that and, again, thanks to the repair video I changed the motor. This fixed the problem and actually this 21 year old dryer sounds better than it has in years. I can't stress how valuable the repair videos are. From now on I will look to ApplianceParts Pros.com for all my appliance parts. Thank you so much.
