I have been having extruder problems on my Replicator 2, and was making sure nothing was jammed and such. When I was resembling the extruder assembly, my hex screwdriver slipped and broke the fan.

I then started the loading filament process, and smelled burn, and saw smoking coming from the assembly. My thinking was that it was probably the fan, so I went to unplug the fan, when I notice that the extruder motor was extremely hot. I had just started the loading process. I did test and it heats up quickly. I would say around 60-110C. Scary hot that I had to turned off the machine and unplugged.

My questions are if I may, could this possibly just because the fan broke. I doubt it.
Second. Could I just replace the motor, or could this be a problem with the board, or wiring? The exposed wiring looks fine to me.

FYI The fan I speak of is the one in front of the machine. And my machine has 800K hours.
