Table saw capacitor heats up and explodes.

You can only tell by using a continuity tester or a multimeter and some troubleshooting techniques.

Simple solution: switch two of the wires. Doing so will reverse the direction of the motor. You can switch it at the motor or on the electrical plug end.

Check to make sure the arbor set screw is not loose. The bearings may have shifted when you moved it. I recently rebuilt an old 66. Repositioning the bearings and tightening the set screw could be all it needs.

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.

You may have lost power on one of the wires to the motor. Check the wiring for breaks, if you have a meter make sure there is power to the 2 110 volt wires.

That is the current setting for a motor-starter which is an overcurrent sensor. This is a circuit breaker like device that usually has a heater coil that opens a contact which cuts the power to the relay that powers the motor to prevent overload damage to the motor.

The dial is in AMPS and should be set just slightly higher than the nameplate amp rating for the motor.

If the motor runs without the switch then the problem is the switch. Pull out and blow it clean of sawdust and try again. Also check the connections at the switch to make sure they are tight.Hook a meter up and turn the switch on to check for continuity. Remember, switches wear out also and need to be replaced.

Did you try Powermatics web site?

No. Unplug saw remove saw blade grasp shaft that saw blade was on wiggle back and forth. Should not be too much play. After 10 years motor bearings are proably worn. Easy to replace

Your saw motor is equipped with a two speed internal start switch. Over time saw dust will get into the contacts and cause the points to burn. You can pull the end off of the motor and take some 400 grit sandpaper to the contacts to clean them( there are two sets of contacts one works in the out position the other in the in position) it will be the set in the in position that is the problem. Gentle clean them, reassemble the motor end cap and it will work fine. I have to do this about once a year to my saws. I use my saws about 25 hours a week. I have been doing this to one of my Powermatic saws for 31 yrs. now.
