If everything looks good, then I would check the terminals at the control board with a multimeter to see if they are giving power; if they are, then the fans would be suspect...although it seems unlikely that both fans would fail at the same time.

Is there an option in your software which controls the fans?  Could you have inadvertently turned them off?

Any suggestions how how to get the fans running again?

It is kind of printing. the step extruder is too hot and the filament gets off track. As for the temp readings I don't have any other than the makerbots readout.

- Is the cooling fan on the extruder motor running?
- Does the machine still print while overheated?
- Can you observe your temperature curves or status for the bed and hot end?
- Do you have a digital / infrared thermometer to identify the heat source (hottest spot in the printer)?

   I have a makerbot replicator 2 with about 200 printing hours and recently it has started overheating. And when I say overheating, I mean the whole machine is hot to the touch, and the step motor for the extruder is too hot to touch. I have already tried lowering the printing temps, and the problem is not an environment issue. I suspect the thermocoupler wire. Any ideas?
