Sv06 fan not working when plugged in, but works not plugged in

I don't know if this there is a fix for this or not. I unplugged my cooling fan because it was no working. I tested it out on a 9V battery and the fan spins, however when plugged in - it does not. I don't know if there is a way to test this fan with the stock sv06 lcd or I need to get the klipper. If not, I am not sure how to fix this or what to do to get it to work. If it is a PCB, how could I find out?
