Nordictrack XP1000 keeps stopping
I have a Nordictrack XP1000 model # NTTL09993 I bought it used but it is in good condition overall. I have it plugged into a surge protector. I run it between 3.5 and 4.7 MPH. It keeps stopping about 10-20 minutes into my workout. I have made sure that the belt is clean and lubricated. The screen continues to count the workout but the belt won't turn. I can take the key out and wait for a minute or two and it comes back on. It will run for a couple of minutes then do the same thing. Do you think it's the motor or drive board? Is it worth putting that kind of money into it or should I just go buy a brand new one?
