I also just tested the fan output on the control board by moving the LED light wires to the fan connector and was able to dim/brighten the leds by turning the wheel controls. When I plugged the fan wires into the LED connector it still wouldn't power the fans??

Good afternoon! I could really use some help!! I'm a Dad trying to help my daughters school get this printer working again. I've tried everything that I can think of to get the part cooling fans to come on. Hers's a list of what I have tried so far. The printer is a Ulitmaker 2+ running ver. 3.3.0 I have tried using Cura as well as Simplify3d. Probed the backside of the control board to comfirm that its measuring 24.29v. Another odd bit even when I dial the fan speed down it stays at 24.29% till I reach to 1% then the voltage drops to 24.27v. I have powered each motor with an external power supply and they both seem to work as normal. I have also done a continuity test to see if their's a brake in the wires, but everything was fine there too. I have also done a factory reset. which didnt change anything. With all the testing that I have already done it seems to be a software and not a hardware issue. Any suggestions would be greatly appreciated!! Thanks!!
