After I posted I read the name Ryan O'Cull a number of times in TOTV so called him. He was here with-in 2 hours and had my door running in :10. I was sure motor was gone due to humming and smell. Drive pulley was loose, easy fix. He said he has seen this in MVP units and simply lock nut loosened up and shouldn't have. Very nice, professional to do business with. Thank you for replies.
