Problem turned out to be the Belt Tension Pulley. So, replaced Pulley and Idler Pulley Arm and while at it replaced the Idler Spring, both Drum Support Rollers and Roller Axles and the Dryer Drum Belt. Also did a thorough vacuuming of the lint that had accumulated over the years. The videos on the website of Appliance Parts Pros, are excellent in the detail of the repairs.
