Hi All.
I never received any formal training on electronics, but I learned a great deal because of helpful websites such this one!
I have a problem with my YNOT Treadmill, with a motor control board . I have spent the last 3 months troubleshooting it, and now I am stuck, so hopefully someone will be kind enough to point me at the right direction.
I have contacted the manufacture for technical support, but to no avail. They won't provide repair manual/schematics. They just want to sell a new board at outrages amounts of money and get you to buy a new belt while at it. I figured I could do better by fixing it myself, all the while learning about electronics which I enjoy greatly.
I believe I put too much load on the board by not lubricating the belt properly, and burned a transistor/IC somewhere. It was working fine one day. I turn off the AC switch on the treadmill each time, thinking that would preserve the capacitors. The next time I turned on the AC switch, the treadmill turns on properly, but when I start the motor, it won't turn.
I test schotty diodes and some transisitor (s9015 and s9014) and also i test transistor 78L05 and 7815 still working.
I replaced MOSFET IRF4250 transistor but still not working motor.
Can you help me traced what is the problem for this board.
Please help me guys...
