I am mechanical--- i took the motor apart cleaned it --- it got hot today and triped a breaker at a cusomers house ran ok for a few minutes longer then it stopped the motor hums blade dosent move i think the circut board that would probably have to do with the soft start is bad i checked power going into the board looks like 120 on my not so accurat volt checker after the circut board it lights but not full brightness????/

Re: my saw wont run only buzz
Sounds like teh capacitor has blown. These machines use normally use induction motors so they need the capacitor to take a charge and give the motor a kick in the right direction. You could CAREFULLY turn the machine on and spin the blade by hand. If it runs now then you will need a new capacitor.

Usually a saw that size will have it's own breaker built in, is this the one that is tripping? Or is it the one on the wall? Either way, a dull blade will make the saw work harder, and heat up faster, Mine trips off now and then, always from a dull blade. It has a built in breaker in the switch. Are you running it with a cord? Make sure it is heavy enough, a small cord will steal amperage from the circuit turning a 20 amp breaker into a 15. Hope this helps.
There is a direct short some where.Unplug and turn the blade and listen to the bearings. One of the brushes might be worn down and be jammed against the armature. Five years of use and those brushes might be ready for replacement. If things turn out to be easy fix then changing brushes is not that hard.When you take them out you will see some small holes in the holders.When you put the new brush in the spring will try to push the brush back out,use a small piece of wire in the holes to hold it in.Next install the brushes back where they go.Check the armature out use a hacksaw blade to clean those grooves between the metal strips.Put the armature back in place and button it back together and pull out the keeper wires and your done.
Usually the reset for table saw is on the motor itself Crawl under the table and check it out & check your motor name plate (use a digital camera to photograph the name plate so you can see it large on your computer and have a record of that information) Look for oil caps at the bearing ends of motor, to see if your motor can be oiled using 3-in-1 oil
If your saw is shutting down, you may not have enough electricity for the motor Look at motor name plate for volts amps or watts. Now figure how much electricity your saw need using the formula Volts x Amps = Watts
Next, look at the circuit breaker and size wire 15Amp breaker = 1440+watts You can figure the breaker load using V X A = W
Next look at your wire going to table saw 14 gauge wire for 15 amp breaker 12 gauge wire for 20 amp breaker 10 gauge wire for 30 amp breaker
You might benefit by running bigger wire to the saw. And adding some oil in the oil caps. I oiled my table saw and then ran a dedicated 30Amp wire to it, and it runs real good for a 25-year-old craftsman.
tilt the saw head and then use a screwdriver to gently pry apart. the bearings in the housings are keeping it from coming apart or the armature and or field are melted causing this, either way the screwdriver trick will work.
I just bought this saw used off of e-bay. Got it home check to see if it would run, It did. The next day got the saw out and nothing. By passed the breaker and the switch and it ran fine. Ended up taking the switch out and apart I found that there is a rocker inside that either rocks in one direction (off) or the other direction is (on). the on side has a contact similar to a points contact on an older vehicle. Mine had some saw dust between the contact thus no power. wiped it out and the saw was fine.
