Welcome to the board Nancy. Most of us have been forced to
replace a compressor from time to time and we're not rich, so it can't
be that expensive to fix.

Are you sure it's the compressor causing it not to cool or could
it be a wiring or thermostat problem?
Lastly.........what is a Cavalier CGC-D ? Is it a chest cooler? Can
you post a photo?
