Nordic Track EXP1000i suddenly stops
After walking for about 45 minutes at about 3.5 mph the treadmill suddenly stops. If the power is shut off it will start right back up and run for another 15 minutes (my normal 60 minute walk time) with no problems. A new belt was installed about 6 months ago and I check the belt tension and lubricate the belt on a regular basis. Any suggestions of areas I need to be checking for problems?
