PaceMaster ProPlus II treadmill. I am having trouble with a recurring Error 24. Usually it occurs in the middle of a workout and most often at about5.7MPH. It then may take 2-3 tries to get restarted. Finally I am able to complete the workout.
Rarely happens at any other time, but has happened at other speeds. I believe the belts are adjusted properly. I also believe the speed sensor is ok.
