Outside a/c suddenly quit today- trips breaker

Carrier 38TG036310 a/c
Was cooling normally until 4PM today, then stopped cooling. I could hear the system trying to start repeatedly. Fan blower continued to run. Outside breaker was tripped. I turned the system off, reset breaker, and tried it again. It tripped the outside breaker and the inside breaker immediately. I moved outside fan blades; they turn easily. No odor of burnt wires.

What is the probable problem? Any chance it is something relatively inexpensive?

Thank you for your time and attention.

Sounds like the compressor is your issues. With the breaker tripping right away, sign of a shorted unit...

Turn power off, and remove service panel to make sure there is no wire that is short in the wire, and also do you have a meter?

Could be major, such as a bad compressor. Or something minor like a start capacitor or wiring burnt on the compressor terminals. The spade clips get loose after a while and heat up because of resistance. There are kits to replace the terminals now. "Term-lok"
Depending on how old the system is, and if the compressor's bad, it might be wise to go with a new system. More efficient, 0% ODP refrigerant. With 13 SEER & up, you could get a DOE rebate, too. Varies by state.
