First Dryer installed did not have a belt attached and the Installers found other problems so they went back to the warehouse and brought us another new machine.  When drying our first load of towels, heard a scraping noise. intermittently.  Repairman discovered a it was scraping on metal shield.  Solution was to bend the metal downwards less than and inch to avoid contact. Upon his inspection one of the belt pullies seemed to flawed so a new one was ordered.  After repairs things seem to be working fine.  Give the Service and Installer 5 stars. Quality of Dryer would make be look for another brand next time.  We have purchased and used GE appliances including our previous dryer for many years and never had this much trouble.
