Nordictrack C2200 model # NTL10905.3 speed goes to zero at random times during walking workout
We have a 17 year old Nordictrack C2200. It has 1071 miles (233 hours) on it. When I am doing a walking workout the speed will randomly go to zero. It never shuts off. I just reset the speed and continue my workout. The belt doesn't slip or get stuck and isn't worn as far as I can tell. What could be the issue? Control board? Something to do with the motor? Lubrication?
