I first watched a video on the issue at AppliancePartsPros.com. That showed me how to get to the area that I suspected was the issue. I opened the dryer and confirmed that the part had failed. I ordered the part from AppliancePartsPros.com, the blower wheel assembly, and swapped it out when the part arrived. The tutorial from APP made it very easy to do and I trust them to send me the correct part for the job.
