Sole F85 Treadmill Speed Issue
Just got a used sole F85. Everything appears to work, other than the speed control. It will speed up after pushing the increase speed buttons but it will not slow back down if i adjust it. Example, I will set it to 6mph, belt will speed up, then when I attempt to slow it down to 2mph, the motor does not change and keeps running at 6mph. It also will keep spinning at the 6mph even after I hit the "stop" button. Only way to stop the machine is to remove the safety key. Any idea what this could be?
