Any electricians out there? Please help

My air compressor will turn on and run but some times it will flip the breaker than when I flip it back on you can hear a humming sound and it will flip again. Let it set for a min. or two and it will start and run again. Well to day the breaker would not even make a noise when I flipped it back on. I let it set for about 5 mins. Then it turned on. Is the breaker bad because when I felt it was a little warm? Or is there something in the wiring?


Thanks
