The blower fan blade is held on the motor shaft with a two piece clamp that over time weakens and loses its grip allowing the fan blade to slide out on the shaft and rub against the metal mounting plate. I had over the last 15 years repositioned the blade several times. Each time my repair would work for a shorter time. Using your video guidance I was able to pull the motor and blower assembly out of the dryer and replace the fan. The old fan had worn the flat spot on the blade to where it no longer stabilized the blade on the shaft. I highly recommend taking pictures of all the wiring attached to the motor prior to the disassembly. While I had everything apart it was easy to replace the front drum bearings which were worn. I also replaced the front bearing support because one of the bearing locking tabs had broken off during a previous repair. I had searched several web sites before I discovered yours which was the first one that even recognised my model number. Parts delivery was outstanding. I highly recommend you to all of my friends and family. Thank you.
