Half way through cuttig a 2*4 my crAFTSMAN table saw cut out. Hitting the trip switch had no effect. Power source is good. Is there something I'm missing

I can't find any reviews or enough information about your saw. Try posting a thread to craftsman support site or call them perhaps.

Maybe, but first rule out several other things. Has the saw been recently overloaded - heavy cuts with a dull blade? You may have a partially burnt-out motor (which means the insulation on the wire in the windings has partially melted.) Has it been used recently or used now with an extension cord or to an outlet wired with 15 ga wire? Is the saw arbor hard to turn by hand (with the belt removed)? Does the motor overheat with no load (remove the belt and let it run for 10 minutes)? Try running the saw with the belt on, but not cutting for 10 minutes.
Good luck!

First of all, how did you determine that power was getting to the motor? If you can test for power with a voltmeter at the motor connections themselves and show power then the switch is OK and the circuit breaker is not tripped. Turn off power and attempt to turn the blade " CAREFULLY" and if it moves easily then the motor is probably defective and will have to be replaced. After turning the motor and finding it easy to turn, then turn the power back on and try to start the saw again. Be carefull because the saw may start. If the blade will not turn then the motor is definitely defective and will have to be replaced.

Good Luck!

First things first, check the outlet that the saw is plugged into. Does it have power? If so then progress to the saw itself and check the reset button which is usually located on the front panel but sometimes on the back or sides. Press the button firmly to make sure it is not tripped and if it is this will reset it. Make sure the power is turned off and attempt to turn the blade manually ( caution,
the blade is sharp so a pair of gloves is recommended ). If the blade turns with very little resistance then turn the power back on and try the on/off switch. If the saw starts it may very well have been the circuit breaker that had tripped.

Go to searspartsdirect.com and put in your model number. Look at the motor and wiring section. Look at item 16. The motor overload protector. (probably your reset button) WIth saw unplugged, unwire one sid of this switch and test with an ohm meter. You should read through the switch. If it is open then that's why the saw doesn't work. Many of this type of oveload requires quite a push to reset as you're flexing a klixon disc back to make contact. If is open and you can't reset, it's available there although a bit high priced.

Sounds like you may have overheated the motor. I'm surprised the overload on the motor didn't trip first. With this overheating, the windings in the motor have basically shorted out to ground. This is why your breaker is tripping. Rewinding the motor is no longer the option these days. You can try going online to www.searspartsdirect.com

Could be the motor burned out. That shouln't happen and if it did craftsman is really good at replacing damaged tools. I'd return it for a replacement.

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. .

On some motors they are not sealed saw dust gets in the motor and can cause them to overheat they have a themal coupler built in the motor it is being tripped .On sears you can got to sears replacement parts and get a new coupler.If you are not familiar with electric motors.Please take the motor off unplugged!!! mark the ends and caps with a mark or line so you can line them back up on either end .Remove the covers on the ends clean out the motor if full of stuff blow out or use a can of electric motor cleaner available auto parts stores clean all parts find the coupler go to craftsman parts they have a parts diagram online so you can identify it replace it try again if it still does it replace the motor or the saw.

I had the same problem several months ago with a craftsman (shut down during a long rip), and the reset switch had tripped but did not actually pop out. I tested everything in the line between the power supply and the motor, and found out that the reset switch was not conducting. I was able to reset it manually before re-installing it into the saw, and it's been fine ever since. I'd test that before you start pulling the motor out, it would be a much easier fix if the switch was just sticking.
