A failed power supply, broken on/off switch, bad motor overload, broken power cord or failed drive motor can prevent the table saw motor from starting. First, try resetting the overload. If the table saw motor won't start after resetting the overload, then the saw may not be getting power from the electrical outlet.
In your service Manuel you'll find the location of the safety triggers. It's highly possible one of them has a bad connection. Very briefly and carefully jump each one till you see a change to eliminate them one by one.
Hi Welby:
My saw is not a DeWalt, but the procedure should be similar.
First, WORK SAFE! UNPLUG THE SAW.
Now you can explore without the prospect of having it bite you.
Here are the things I would do:
1) Set the On/Off switch to OFF
2) Have a look at the motor. There should be RED (typical) reset button. When you find it give it a good solid push.
3) Check to make sure the On/Off switch is still OFF.
4) Plug in the saw.
5) Try turning it on.
If it does not work, I would unplug it and use a continuity meter to start checking the various components, especially the On/Off switch. If it has failed and you can't get a replacement you could
do as I have with an old Craftsman. It is 110 or 220, and has only been used on 110. Half of the switch terminals had arced over 40 years of use, so I just re-wired the switch to use the other terminals but still be 110. .
