What is wrong with my Horizon T101 treadmill?
After lubing the treadmill belt of my Horizon T101 treadmill, my treadmill is not working. I pushed the belt to move it manually and went really fast then slow. It kept changing speeds. Also when not manually pushing on the belt to move it there is an E1 error. Could it be the speed sensor? Any advice on how I can fix it? I'm going back to school and don't have much now.
