Print bed temperature too high

Hello,

I have an older version of the R1 (the one with the regular cable for the heated print bed. The cable broke, so Robo 3D sent me the new upgraded ribbon cable setup for the heated print bed. I installed it, but now the temperature sensor seems to be reporting bad values. When I first turn the printer on (at room temperature), the software says the print bed is 40 degrees celsius. Seems a bit high!!

Is there a firmware setting I should change or did I mess up installing the bed sensor?

Thanks,
TIM

 

About 25 is room temperature. Does it show hotter if you set the bed temp above 40c?
