Daveht,
Great recommendation. I pulled the unit apart yesterday to replace the squirrel cage blower, sail switch, and front cover (tabs broken). What I found during the disassemble is the the band clamp that secures the fan motor was finger tight so it had obviously caused the squirrel cage fan to float within the unit, which could have caused the fan to come in contact with sail switch, edge of cover, etc. When I replaced the squirrel cage fan only it appeared there was still interference (squealing, clicking etc) Once I replaced all parts at properly secured the motor with the band clamp there is no noise at all, just the hum of the motor and woosh of air.
Thanks again for the suggestion, you helped me get there!!
