Nordic Track APEX 4100i speeds up
My Nordic Track APEX 4100i starts out at 3 and by about 10 minutes in, it randomly speeds up to 4+. If I step off it to the railings, it returns immediately to 3, but I step back on and immediately picks up speed. This has been a wonderful faithful treadmill for probably 20 years so would love to be able to fix.
