Fan motor hums/buzzes when turned on. Blades turn very slowly.
Toshiba EFS 75 Standing fan
My standing fan stopped working and whenever I turn it on I hear either humming or a loud buzzing noise and the blades turn very slowly. The blades spin by hand easily enough when the fan is off, so I'm sure there are no problems with mechanical friction or obstructions. However, as soon as I turn the fan on the blades suddenly get a lot of resistance to them. I even tried to get the blades spinning at a moderate speed before turning the fan on, but when I do the blades stop quickly as if the motor acts like a magnetic brake.
Looking online, the most common diagnosis to this problem was a faulty motor capacitor so I took that out and replaced it yet the same issue persists. Another solution I found is to check the leads on any sort of starting clutches but it appears that this particular motor is a simple, single capacitor motor.
