I have a treadmill and the motor control circuit board keeps blowing up. I= 've done research and they are "prone" to doing this, but no one will say w= hy. I believe it to be the stress the components take during the power sur= ge that takes place when the unit is turned on by its toggle switch.
Question: Does anyone have any idea about how to build a surge protection = circuit that will clip things so the board doesn't blow? I know there is p= robably an amperage rating that needs found out, but I don't know the best = way to figure that; but the board takes in 110v 60hz straight from the togg= le switch already mentioned...no circuitry in between the wall plug and the= board.
Thanks much for the help...humbly and thankfully...Tom
