Using Marlin, Pronterface. My hot end (j-head IVb) shows 114 degrees C for ambient. It's done this with 2 different hot ends, so I don't think it's the thermister. Any ideas?

Check to see that the wires on both ends of the thermister are not grounding out against the metal of the hot end block. Did it just start doing it?
