True 500A P - True 500 P Treadmill Review
I weigh 150 lbs. and have used it about 2 hrs. every day walking at 3.7 mph up a 12% incline, and had no issues until now.
It is erratic, and speeds up or stops and restarts abruptly, and is certainly dangerous.
Time to get another unit, True's Control boards are not reasonably priced @ $387, and that is for the board repaired, not new.
Had no trouble with it after buying it used about 6 years ago from someone that probably didn't use it much.
