Heated bed is not heating anymore I have built a RepRap Prusa i2 a while back. It worked for a while, but then I moved the printer from place to place and after a while I noticed that the printer's bed is not heating anymore. The thermistor shows the temperature (room temperature), but the bed is not heating. 
The wires are connected and the heated bed has a resistance. 

Did anyone else confronted with this? Thanks!
I have a Prusa i3 and the same case happened to me. I checked the continuity of the wires and discovered one badly soldered wire in the heated bed. After soldering the wire correctly, the heated bed turned on again.

Your problem is in all likelihood the continuity of the wires.

I hope that I helped you with your case.
