Hey, I have a sort of weird question. My delta unisaw tripped tonight because I had a heater on and I can’t run both at once. So I turned off the heater reset the breaker and I thought I was good to go. Well after I cut my piece I went to turn it off and as I hit the off button it tripped the switch again and now I can’t turn it off. Is there some kind of reset inside the box or did I fry something. Thanks for your help in advance….Dave

There is (should be) a manual reset in the starter. I’m guessing you meant to say you can’t turn it on, not off.

Cheers,
Brad

Brad, No I am right. I can’t turn it off. Every time I hit the off button it trips and when I reset it, it starts again. The only way to shut it down is to turn the breaker off or unplug it. I have the manual. I’ll look in there for the reset. Thanks

Then you shorted something somewhere. What kind of starter do you have? Need more info.

Cheers,
Brad

Not good with electric. I know its a 220 line. The box is fairly large and has a separate on and off switch. What else would you need?

Oh man, there are just too many different configurations to offer any real guidance here. Post some pictures and describe what it’s doing a bit clearer. Tripping? Tripping what? The circuit breaker in your panel? The overload on the Saw? Walk through what you do and what happens when. Was it working fine until you tripped the breaker when running the heater? Did it work after that and then stop later, or did it start acting up immediately after tripping the breaker? If immediately, it could have been a short in the saw that tripped the breaker, not the heater. Just too many unknowns here to really narrow it down much.

Cheers,
Brad

Stop feeding it mushrooms..

Seriously, what kind of breaker are you using? Running a straight resistive heat load on a breaker and combining it with a large motor surge may have damaged the breaker. Try using a different breaker if you have a similar one in the panel.

The saw worked fine before. I can’t use both at the same time and I did and that’s when the breaker popped. I unplugged the saw and tried the heater and that was fine. Then I unplugged the heater and tried the saw. The saw started and then when I went to shut it off, that’s when the breaker tripped again. So I reset the breaker and the saw started running again. It never shut down just tripped the breaker.

Is it a magnetic switch? If so something is hung up in it and needs some cleaning.

^That would be my first thing to check too. With the saw unplugged, don’t just trust the breaker turned off, open up the starter and see if the magnetic switch is still closed. It could be some grime has made it not able to move freely so it’s stuck in the on position. Read this thread for some ideas to look at.

To everyone who helped me out with their suggestions, thank you. I had a friend come over and he took the starter out to look at it. So far he didn’t find anything wrong. He’s trying your ideas now. I’ll let you know the out come.

Have your say...
