Toro model 51575. Was using it as a vacuum and it just shut off. Checked breakers ...all ok. Plugged it in direct to outlet and still nothing. What might be the problem?

If you're Toro electric blower is slowing down, throwing sparks, overheating or not starting you may need to replace the carbon brushes. Replacing brushes and cleaning commutator early can prevent damage to motor armature!

5 minutes everytime? If so, raise brush all the way, and vacuum next to nothing. in fact, tilt vac up so the brush touches nothing. wait 5 minutes. If it doesn't shut off, your brush is set too high. if it does, the motor is over heating. make sure bag is empty, no debris in brush, filters clean and make sure you're not plugged into an outlet that a breaker on the outlet can pop too.

You said you checked the main breaker but did you change the fuse in the plug

The blower was still under warranty and Toro is replacing it.

Hello mdonettaYou said,
Dryer shut off towels were not yet dry, turned dial to restart dryer acts as if it isn't getting power I closed door and pushed start button. Nothing! Checked breakers and power cord at outlet all checked okay. Any ideas.

yes, try unplugging the power cord or turning off the breaker for 5 minutes. Either will due. Some times the system needs to be reset!
If this does not work there are internal fuses that can be replaced!

Let me know how it goes!
Huuum

Of course it could have nothing at all to do with the sweeper. Has anyone checked the outlet you tried to use? It may be at fault. Someone may want to check the circuit breaker box for a blown breaker leading to that particular outlet. If that is not the problem, you should be able to call for repair services as the NSS Pacer is an industrial sweeper and must have a pretty good warranty.
