Was wondering about what might cause this problem: after finishing ripping a 1” board I switched the table saw off to bring another board; pushed the start button again, the blade just jerked a bit and that was it. The motor was barely warm, no dust. Waited some time, reset thermal overload switch, changed the extension cord—didn’t help. The blade just jerks a bit after every first push on start button.

Do these simptoms sound familiar? Would appreciate any comment! Best, h.

I have an old JWTS-10 saw that had the same behavior and I noticed that the plug connection—there’s a plug and connector near the motor—not the plug that plugs into the wall outlet—was not good—looked like it had been arcing. I cleaned it up and slightly bent the connectors so that they would make better contact and the saw started up just fine.

My guess would be a bad start capacitor since the blade does move a bit.

Thanks for the feedback. This is a relatively new table saw, bought in 2016. I called Jet CS and the guy suggested to bypass the ON-OFF switch, the one with big green and red buttons. According to him the most common cause of the problem is the dust in the switch assembly. He actually made me first switch the saw on and off very fast for 10 sec in an attempt to clean off the dust. It didn’t do anything.

But after I bypassed the switch, guess what, the table saw works normally. The ON/OFF switch is to blame, even though it looks well sealed inside a plastic case. I called the customer service again and they said the switch is under warranty so they are sending out a replacement.

Great idea to call Jet and get them involved. I am certain that they have dealt with this and many other problems on numerous occasions. Sounds like the service guy nailed it and then you following his advice to bypass the switch confirmed the diagnosis. Kudos to Jet for providing the replacement switch assembly without making you jump through a series of hoops. I hope the new switch does the trick. When (not if) it does, open up the original to have a look and to confirm dust as the problem. Clean it and keep it as a spare. If there is something else wrong with the switch let US and Jet know for future troubleshooting reference.

Yes, I definitely will try to make it work again. However, it’s just a sealed plastic assembly with six terminal screws and two switches—not much to clean.
