I have a common problem with a Horizon Treadmill I need some some help. Everything works but the belt doesn't move. I've learned alot from this site on what to do but nothing has worked. This is what i've done so far.
-Motor runs on a separate 12v power supply.
-replaced fet with irfp260n
-replaced kickback diode with f30u60
-replaced Q2 with s6025l
-Bridge rectifier tested good
-replaced all 3 capacitors
-replaced D13 and D14 diodes
-replaced IC U1 is6010 with moc3023 i think this is compatible, couldn't determine if it gets mounted a certain way.
-resoldered relay pins.
Is there anything else i can try? Keep it simple i'm new to this.
