I would like to add something to this step. My dad has a box fan that was his dads. Thing is really old. It stopped working because he left it out in his pole barn and the dampness got to it. It would hum so we knew that the coils were getting electricity in the motor but it just wouldn't turn, so I knew it was the bearings. I opened the motor and I cleaned the dust out of it. I can't remember how I did, I want to say I used WD40 but I'm not sure. Maybe I just cleaned it out with a brush, but I did the same to the bearings. I then put some heavier motor lubricant on the bearings and I worked them around a bit, then I stuck the motor back together and I put a little more lube on the bearings and I worked the motor around a little, plugged it in and it turned on and it works as good as new now.

If you have an air compressor, it really helps to take the unit outside and give it a good blasting with an air blowgun, especially the motor,
