nordictrack T7si speed control

mgarst

Treadmill is running way too fast. It averages 2-3 mph above any setting. When in calibration mode I put it to the max 85 setting and its reading a swift 15.4 mph when it should be 10. I moved the potentiometer as low as it will go and it doesn't make any difference in speed. Is this a bad controller? Or is it possibly coming from the console? How do I determine source? Thanks

Its a bad motor controller for sure.
