Delta Radial arm saw 33-990 tripping circuit breaker

Hello I have had this saw for 8 years with no problem. It is on a dedicated 15 amp breaker. It has just started to trip the house breaker after about 1 minute of running. You do not even need to be cutting anything. Just running the motor for 1 minute or less will trip the breaker in the house. I am not sure if it is the motor or possibly a capacitor. A new motor is $680 dollare while a capacitor is $80. A whole new machine is $780.

Delta Radial arm saw 33-990 tripping circuit breaker

I doubt the motor is bad. Try it on another circuit to see if the same problem exists. Due to the inrush current of the motor, the circuit breaker may now be defective after several years of use.If you have the ability, determine the no load current on the motor, and then try it cutting a piece of determine the load current. If it is within the rated current of the motor, then it's fine.

My Delta radial saw motor keeps tripping the GFCI circuit. I've tried several separate circuits and they all trip as soon as I turn on the motor (even a 20 amp dedicated circuit). I took off the motor housing and blew it out clean with my air compressor. Still no dice. Any thoughts? Thanks, Phil Wendt

Saws draw a lot of amps at start up and will normally blow any GFi circuit, if it does the same in a normal outlet,, you might have to disassemble your saw for a good cleaning and lube,,

Sounds like you may have overheated the motor. I'm surprised the overload on the motor didn't trip first. With this overheating, the windings in the motor have basically shorted out to ground. This is why your breaker is tripping. Rewinding the motor is no longer the option these days. You can try going online to

I have a Delta 10" radial arm saw. It was running fine. I lowered the arm to much with the saw off and when I turned it on, the saw overloaded and kicked off before I could get it raised. The reset button will not pop out, and the saw will not run now. Are these reset buttons hard to replace and are there any reference materials to show you how? Where can I get parts?

The Overload reset circuit is located inside the starter assembly box on top of the motor and it is easy to replace by removing protective cover undoing de-soldering and soldering back the contacts.The overload circuit is located inside the protective box at the top side of the motor, and it is part 180 on circuit below.Before replacing the overload , test and eventually replace the starter capacitor and start meter.Here parts to be tested and eventually replaced: 180 1345843 START CAPACITOR 1 1345843 180 1345844 RUN CAPACITOR 1 1345844 180 1345845 START SWITCH MODULE 1 1345845 180 1345848 OVERLOAD 1 1345848 Here also the whole box assembly, you won't need to test in that case, but the whole assembly is expensive.MTR 1PH 1.5HP RA10They are all located on starter assembly that is the box on top of motor.Capacitors can be tested with a capacitance tester: NEW DIGITAL MULTIMETER W/CAPACITANCE TESTAlways discharge capacitors before testing.An alternative way to test capacitors with a regular multimeter is the one explained here : How to Test High Voltage Capacitors. The procedure is the same on the starter and run cap on your saw, that are high voltage capacitors.Switch and overload switch are instead simply tested by reading voltages with multimeter, and ensuring they open and close.Overload and starter are inside the box numbered part 180 on diagram below:Parts Diagram (Page 2)Here all the diagrams: 33-890 Type 1 Parts Diagram (Page 1) 33-890 Type 1 Parts Diagram (Page 2) 33-890 Type 1 Parts Diagram (Page 3)If this is what you were looking for , do not forget to leave feedback, or Fixya system will reward first comments by default.Many thanks.G.

The saw should have a centrifugal starter winding switch on the shaft. The weights swing out and disengage the switch once it is up to speed. The switch probably has dust in it or a burned contact. You might be able to buy it but it should be easy to disassemble and inspect and probably clean up to work again. I did mine.
