I got it to work! I saw on the back of the motor, where the cord connects into it, a little black piece with a separate small piece that seemed to be movable. I originally pushed it in, thinking that was the on switch, but it didn’t turn it on. Then when I got home from work this morning, I decided to try pulling it out some. That seems to be the power switch, because now it works. I guess when it’s pushed in, it breaks the circuit, but when pulled out, it completes the circuit. Thank you all for your replies! I definitely appreciate it
