Compressor stopped working after two days

Usually a capacitor going bad will cause something of that sort but if the compressor has age it may require a super boost capacitor to help it start. Both of these items have to be purchased from a distributor. I have access to the parts if you want to try that other than that I hope the info helps.

It could be one of four things, a bad run capacitor, start capacitor, start relay or the
compressor is locked up.
I would think it's either the run capacitor. A lot of times you can look at it and if it's bulging even slightly then it's bad, if not it's probably the start capacitor and relay I add the relay in because when you change one you should change the other also..
