Thanks for the help.
After further inspection it appears the mosfet is stuck closed (sorry for misspeaking before), and I'm ordering a new board to replace it now.
Until then, I was hoping to dive into the firmware a little more and try to redefine the pins to the available mofset on D7 since I'm only running a single extruder. I'm more of a mechanical guy, so diving into the firmware is a little intimidating, since my only coding experience is from reading REPRAP firmwares. Any advice for changing the cooling fan pins from D9 to D7? I'm a little lost while trying to change it, and always receive an error while compiling.
