My Repair & Advice
The blower wheel center was worn down and spinning freely on shaft. Removing front covers, controls and brackets gave access to blower, which front half came off removing screws. (One screw underneath bracket) Pushed new blower on. (It's keyed and has small tabs that line up with groove on shaft). Installed clamp, reassembled and tested. Don't forget to pull the plug out before working on any appliance.
