Went to this website and looked for possible causes and needed to fix it or buy a new dryer since my wife washes and dries clothes every Friday morning. Watched the repair videos , removed the front cover and discovered that the blower wheel was damaged by a 2 inch wood screw, a dime ,a penny and a butt connector all of which were in the pocket of my work pants. Still haven't figured out how they got past the lint screen. I then ordered a new blower wheel and retaining clip and while I had it apart I decded to install a new tumbler bearing kit. Total cost including two day shipping was $54. A new Maytag dryer would have been about $600. The dryer was back up and runniing before the next Friday wash day. Probably 1.5 hours to disassemble and 2 hours to install the new blower wheel and bearing kit and reassemble.
