Sometimes, when these bigger compressors go bad, they pull allot of amps which often is too much for the little solid state relay to handle. While replacing the relay "MAY" get it working again, if the compressor isn't replaced also, the replacement relay will die in a short time because the root cause was not addressed.
To see if the compressor is possibly locked up, try putting power and a ground to it and see if it comes alive. If it doesn't work at all, you "may" get away with just replacing the compressor.
