Review on 🌀 NuTone 5901A000 Blower Wheel Assembly: Superior Efficiency and Performance by Devin Jenkins

is available Save money and use this as a solution for noisy NuTone fans. If the engine runs well and the electrical system is fine, the cause of the noisy fans is the connection between the metal shaft of the engine and the small hole for the plastic fan wheel. Over the years, the perforated D-shaped plastic fins and fan wheel do not stay on the motor's metal shaft as tightly as they should. Then, when the exhaust fan is turned on, the motor runs normally, but the plastic fan wheel slips, vibrates, makes noise and runs inefficiently. This new plastic fan wheel sits very tightly on the axle, which not only eliminates vibration/noise, but also allows the fan to work much better. Like new. Also, don't be fooled by the crazy old numbering systems NuTone uses for its exhaust fans, motors, and fans. Just measure your old plastic fan. If it's 6" by 2" and looks like this, then buy it. People who replace the motor with a flywheel are paying for a new motor when they don't need it!
