Product review (5 stars): Exact part for a noisy, tumbling sound
I had replaced a bad wheel a couple times and thought the sound I heard this time around was yet another wheel.  When I took the dryer apart and saw the wheels in good shape, a quick search on Google showed that it could be the blower wheel. After doing a check to verify that the wheel spun freely without resistance, I knew I had to change it.  Installed with ease.  Works like a new dryer
