Product review (3 stars): Make sure drum not binding
My humidifier drum would turn 90 degrees, make a loud click and retry. Thought the internal motor gears were stripped so I overpaid for this should be $5 motor. Worked for a day, then did the same thing. Upon closer examination, I noticed the clip holding the sponge part to the shaft had rotted and the sponge crept down the shaft and was binding, causing the internal torque limiting gear to slip to save the motor. Easy fix, so I pulled my old motor out of the trash and now I have a spare.
