Howdy,

I was ripping up some 4/8 harder than Hell mystery wood. The TS said “uh uh” about 2 feet in. It tripped.

I decided that the mystery wood didn’t need to be ripped real suddenly. I confidently said to myself, “I think I’ll just find the reset button and give it a push.” Guess what? No reset button. After reading the owners manual, it’s looks very much like I need to replace the entire power switch.

Really? Really? Naw… Really?

Have any of you “TRIPPED” over this problem? What am I missing?

The brushes are real easy to find along both sides of the motor so I’ll replace them for grins.

-- Thanks for all the lessons!

My old table saw once quit working on me that suddenly also. I was cutting wood without any difficulty and then two minutes later I tried to start it and the saw ran really slow. I took the motor to a repair shop and they replaced the start capacitor for $90.00 and it ran great again.
The motor didn’t have a reset switch and I don’t think most motors do (except those small direct drive do I think). Hope this helps.

Did it trip the circuit breaker in your panel board by chance? My radial ard saw will trip that breaker before it trips its own. Just another possability.

Russell thanks for the tip! A lot of people miss that one especially in the middle of the day working on the driveway. They don’t see the power go out because there are no lights on.

We’re good. No breakers are tripped.

I think it’s a fruitless excercise to be at Lowes looking for brushes. Yet, I’m here. Lets see what they say.

The Lowes guy looked baffled when I asked him for brushes.

Mine did the same thing and I had to replace a little PC board.

The fine folks at Bosch went out of their way and were very helpful
and knowledgeable.

Maybe give em a call. Good luck now.

Howdy Wahoo.

I went through the entire parts list and found a few things that might actually be applicable. The chip you refer to can only be imbedded in two places that I can see. On off switch ($19.00) and the speed governor ($37.00) I believe it’s the latter. The dawgone thing is in-side in the motor housing. That right there makes me want to stop and let the Bosch service folk fix it.

However, If you fixed it yourself, we might give it a try. My son is eats circuit boards for breakfast. ;) Maybe He’ll give it a go for me. Tell me, Does this look about right?

If it does – he might be able to just fix it himself. The thing is about 2X3 inches and the circuits look solid state basic. I don’t see a chip.

NM – I’m blind. 2 chips are visible. I showed my boy this image and he asked me if I was blind. I’m not blind, just embarrassed. There will be no repairing the circuit. I’ll talk to Bosch and see what they recommend.

Ok, Now I’m totally embarrassed. The breaker box is just fine as I stated earlier. I walked out to the garage and looked at my surge protector. You guessed it! Tripped! Oh lord. It’s one of those beautiful humbling moments in my life.

Thank you all for the help. Enjoy the laugh!

Experience. ...there is no substitute. ;-)

Glad you didn’t have to replace the saw or any parts therein.

I am glad that all is well. However, I wonder how many people run their tools on surge protectors and if they are really needed. I typically have surge protectors or UPS on any of the electronics in the house but I did not think they were designed for heavy duty use with motors.

What do others do for surge protection?
