David B Klamath Falls , OR January 24, 2023 Noisy and rumbling sounds. My original blower was loose on the shaft. It also did not have the flat area to engage the shaft. This new blower has the flat area to positively drive on the shaft. This really quieted down my dryer and should dry the clothes better.
