When I turn on the elliptical, the ramp calibrates, then the console displays the track, the word "ramp", and in the top right corner of the display, it says "FF". The display locks at this point, and nothing else works. It does not go off by itself, and when I plug it back in, it goes through the same startup process and stops again. I have checked the wiring harnesses and they seem ok. Any ideas? Sure hope it isn't the console... $215....
