The other night I was planing some 6" wide butternut boards when my 15" shopfox planer w1742 turned off. I can restart the planer if I hold the on switch down and it works perfectly, but as soon as I let the switch go it turns off again. I tried pressing the reset button on the thermal overload relay with no success. I also checked the receptacle by plugging in my 3hp jointer and it works like normal. There was one time where I was able to get the planer going again without have to hold the button down, but as soon as I turned on the dust collector (on another circuit), it shut down again.
So, do you think it is a problem with the start button, the magnetic switch, or something else? If it is the magnetic switch, are there serviceable parts in them? I would rather fix than just replace.
