Hello,

I have a new to me Grizzly 1023RLX with 3hp motor and It has starting problems.

Sometimes I can push the start button and it will turn on and run fine. Sometimes it will stop running when I let go of the start button. I can push it once or twice more, and sometimes hold it in to make it stay on.

I can always get it to run, but it can be a pain in the rear. I have checked the mag switch for dust, and it is pretty clean, but that is it so far.

Does anybody have any suggestions?

Scott

UPDATE 9-20-17 After researching and some of the suggestions here, i believe it could be the on/off switch itself. I pulled it out today, and discovered that in addition to the magnetic starter, the on/off switch is also magnetic! Seems a bit overkill, but the switch is not really momentary. If there is voltage present, the electromagnet in the switch will cold the contacts closed until power is interrupted or the stop button is pushed. Remember, this is in the switch you press to turn on the saw.

I am looking to replace this first to see if it fixes the issue. Does anybody know of a replacement for this switch, a Kedu KDP17B? I would be happy with one that functions as a momentary. I have removed the external button portion in the below pictures.

Have you checked the start capacitor?

When I had issues with my Grizzly table saw, I had to check it and that was the problem.
They told me to put an ohmeter on it and if the numbers slowly increased, then it’s working.
If the numbers jump around all over the place, it’s gone bad.

In my experience, when a start capacitor fails the motor will only hum when current is applied, and will run if the motor is spun manually with power on (can’t imagine there’s a safe way to test that on a table saw).
You say the motor will sometimes “stop running when you let go” of the button. Since this model comes with a magnetic switch I believe that is the part that is intermittently failing.

The seal in or auxiliary contact isn’t making contact. It’s the NO/NC set of contacts that the wires after the start and in between the start/stop go to.

Certainly wouldn’t have anything to do with the capacitor… problem lies in your magnetic switch. Could be any number of things, but it sounds like a loose connection somewhere. Could also be faulty/dirty contacts in the switch or relay contacts, or even a failing coil. Gonna need to do a little more digging than just looking for dust :)

Your key words was its a new Grizzly table saw. I would be on the phone with them if it’s still under warranty. Your symptoms sound like a bad switch.

My bad I misread the new to me. The symptoms sound like a bad mag switch als check all your wire I get connections to make sure they are tight, a split second of no contact or low power will make the switch disengage.

Yeah it could definitely be a loose wire as well coming from in between the start and stop. Trace it out. If it’s well connected then it’s something to do with the contact it goes too.

If the coil was going bad it would tend to chatter.

Hey Scott. I’ve had this happen several times on two different Grizzly machines. In all cases, the starting capacitor shorted out. The resolution was to replace the capacitor and the cebtrifugal switch at the same time. I first called Grizzly tech support who walked me through troubleshooting. They also have a video on their website on how to replace the components.

I now keep a set of these components on hand as I can’t afford the down time.

Google is your friend... I’m sure you can find one out of all those results. Looks like about a $10 (+shipping) repair.
