My air compressor was working fine until i turned it off, 10 min later I turned it back on and it ran very slow, then tripped the circuit breaker

I have a 16 gallon Sears air compressor that starts, runs at a low speed and then trips the circuit breaker. It’s an electric motor. I put a new check valve in it, but even with the line taken off of the pump, it still shuts down. Has worked for years without problem, so it’s something new. Maybe a bad motor or capacitor?

I have a 5 hp air compressor that I can’t figure out the exact way to wire it to the circuit breaker. It is a 208v motor which makes me think that 220 runs it. I’m not sure how exactly to wire this up but I don’t want to hire an electrician if I don’t have to. I would just like for someone to explain the way to wire this word for word to the pressure switch. I would like to hear where the exact color of each wire should start and finish. Where all four of the wires should start in the breaker box would be an idea start for me to begin this process. Thanks for your time.

I have a 13 gallon, 4HP, Campbell Hausfield air compressor that I have trouble with. It will start and run until it reaches the cutoff pressure, at which it blows the circuit breaker. I bypassed cutoff switch and wired it straight to the wall oulet to test the compressor and motor, and it ran fine. I reinstalled the pressure switch and ran it again but stopped it before it reached the cutoff point. When I tried to start it again, the unit dragged like it was under a large load and tripped the breaker. I did this again but before trying to restart, I bleed the air off and it starts fine, repeatedly.
That is when I ordered the CHCW210100SJ pressure switch.
Now I have the new switch on and I have the same problem. Do I have something else wrong or did I receive a new-defective switch assembly?

This is a standard 115 volt, small compressor. It has been running very well for two years on a standard garage outlet. I have replaced the breaker with a 20amp, checked all connections. REMEMBER, if I drain the air down it will start just fine.
