I have a nordic track 4100i treadmill
The only maintenance I have done is cleaning and belt adjustment. Recent it has started something annoying and unsafe. I will be running and it will just come to a dead stop...no warning. It can be anywhere from five to fifty minutes into a run. The timer keeps running but in order to restart the belt I have to turn it totally off for a couple minutes then restart. Help!!!!!

1) Faulty sensor speed try to adjust it face to face magneto motor
2)Sensor speed try to tight the connector very well.
3) Replace if neceesary.4) Main motor faulty or burn. Test 115vac for input measure without load fore easy running.
5) Test the main motor controller board for 115vac input and output for +5VCD,
6) Adjust the deck bel for 2-3" for lift max.
7)Lubricate the deck bel.
8) Test the transformer for input and secondary voltage.
See the block diagram for illustration how the main motor controller has 90% aprox of function of any treadmills.
sincerely. Merry Christmas.
