Extruder Motor not working

Everything was working fine, I was printing stuff off. I changed the filament and then the extruder mother wasn’t working. I’ve checked the wiring and the motor by plugging it into the y-axis motor port and the motor worked then. Also the fan isn’t working, I’m not sure if it’s connected but I can’t find any problems with that either.

Will it heat?
Before it will move the temp of the hot end needs to be above 170C.
