Unplug the band saw. Open it, clean everything up , from inside of the motor, switches , wheels to guides. It could be also a motor problem. Good luck!

How do i turn on a ryobi band saw

First check that it's plugged into a good outlet. Either try another electrical item in that outlet or try the band saw in an outlet you know to be good. Next step; the power switch on the riser has to have a yellow switch key (Ryobi part number 0121010232) in it to work properly. Without the key the switch will not activate the motor. If that's all OK, you should use a volt meter to first check that power is getting to the switch through the cord, then through the cord to the motor. If that's all in order you may have a problem with the motor that can only be tested by a service center with the proper equipment to check the capacitor and armature conductance.

Band saw motor won't start just hums

You will need to take the motor out and check the brushes on the back also check the bearings you may need to disassemble the motor to repair.

D28770 dewalt does not turn the blade. Light works and switch works but not even a hum from the motor.

Check the brushes, if they are worn down to where they are not making good contact with the armature, the motor won't work.
If the brushes are OK you may have to have the armature tested to make sure it doesn't have a short in it.

Powermatic Band saw 143, when i press the start button the saw turns on but wont stay on. When i release the start button the saw turns off. What is the problem. Please help. Thank You, Lee.

Your powermatic band saw has a Magnetic motor starter. Since it is hard to find parts for the 143 you can remove the power and take the starter apart and clean the contacts. If that fails you can take it off and take it to a Electrical Supply Store and have them match you up with one that will work.

The way the switch works is when you push the on button it picks a relay that starts the motor and also has a contact the holds the relay picked. when you push the stop button it drops the circuit.

This is a safety feature to prevent the motor from restarting after a power failure until you hit the button

Hope this answers all your questions

Bosch 4000 table saw will not start. I changed the switch and still won't start, not even a sound. The saw is relatively new, and the outlet works. What should I try next?

A real Weakness of this saw is sawdust and debri entering the cooling ports of the motor causing intermittent contact of brushes which damages the motor speed control board ($40.00). Don't ever operate this saw with out a vacuum saw dust extraction system. Also when you replace the Speed control board also replace the Brushes ($6.00). It helps extend the operational life of the motor components to blow out the contaminants regularly with compressed air through the motor cooling ports (turn off saw first).
You can bypass the speed control board (if you want to disable this wonderful engineering feature by attaching black and white power wires directly to the black and white wires to motor.

My Delta band saw motor is having issues. I was

I would bet it's the Motor Brushes.They are locaded on the housing of the saw, accesed by unscrewing the plug.The brushes are replaceable and your saw will be fixed.Where to buy replacents could be an issue,Check manufacturer or search power tool replacement motor brushes.If stuck you can try to unscrew the plug the brush is at the bottom engaging the motor armerure,there shoud be a spring keeping contact.Inspect brush condition it looks like a carbon block worn to the curve of the motor.Go online do a search on how electric motors work you'll see exactly what I'm explaining.Cheap part easy fix.Good Luck.

The only thing that works is the light. either the switch or motor is bad?

First you must have some knowlege of electricity as it can very dangerous even deadly! With an circuit tester see if there is power going to the switch (switch off). If so turn switch on and check for current coming out of the switch. If yes check for power at the motor end of the same wire. if yes chances are the motor is bad.

You could try blowing some compressed air into the area around the switch and see if it helps.
Otherwise, it's most likely the cord or the switch.
Can you check to see that you actually have power to the switch. If yes, and you feel adventurous, then first remove the blade, then bypass the switch, (using a power strip as a cord switch) to check to see that the motor works, in which case it must be the switch...they do go out.

Here's a link to parts for your saw:
