Powermatic66 single phase 3hp starter switch not working how do I as they say retrofit this switch


it is not the switch. it is the start run capacitor. it is located under the hump on the motor. becarfull when you uncover it, it may still hold a charge. after you have removed the cover you must replace that shiny things that has all the wires in it. careful to put the wires back that way thy came. and get a capacitor with the same UF Microfarits.

I am thinking that you have a problem with the capacitator (if it has one) or the starter windings/switch in the motor itself. If the switch buzzes you are getting electricity to the motor but it isn't rotating and that is where I would start to look. Before this happened did the saw make any unusual sounds or have any problems??? Also unplug tool and look for any obstructions that might have stopped the blade.

When I turn on the table saw, I can hear it humming as if the motor is hung up, but the blade does not move. With the power off, the blade turns freely. Also, I removed the belt and it makes the same...


With the blade and nut off the arbor, turn the motor on and VERY CAREFULLY turn or bump the arbor in the direction it is supposed to turn. If the motor spins up to speed you have a bad start capacitor. I have never been able to find start capacitors for Craftsman motors as a seperate part so you may have to replace the whole motor. Check with any local electrician shops first as they may have the capacitor you need.

My tablesaw will no longer run. I plug it in and turn it on, the blade partially moves and I hear a humming sound


The motor is receiving power, and that is the humming noise.
The humming sound also says the motor is overheating and will burn out.

Turn saw off.
Use hand and manually rotate blade to see if it rolls free.

For example on my saw, the blade barely turned because a bearing was rusted.
I soaked the bearing in wd-40 and 3-in-one oil and salvaged it.
Look for oil ports on each end of motor, and on bearings.
Clean pulleys and belt that connect blade to motor.

If your blade rolls free, and the motor shaft moves freely, then the motor winding has gone bad, so replace motor.

Also take advantage of fixya phone service.
For a price, expert speaks with you over phone while you work on table saw or any do-it-yourself project.
Fixya is always less expensive than a service call.

The table saw shutdown where is the restart button


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.

Blade does not turn


Disconnect the electric from the saw. Remove the throat blade cover. Bring the blade all the way up. Look for wood  caught between the blade and anything else. Finding none,remove blade. Try motor w/o blade. If it runs now,w/o the blade then the motor is likely ok . Reinstall blade. Now if it stil stalls, Replace motor.
