An old (probably 30-50 years) chest freezer is not working. When plugged in it makes a constant, very quiet sound and does not change temperature.
How could I tell what's wrong with it? Is it likely to be possible to repair it?

Repair (by a licensed refrigeration technician) might be possible, but is highly unlikely to be practical or cost-effective .vs. replacement with a modern and probably far more efficient unit.
For one thing, the R12 refrigerant that your unit uses is now absurdly expensive.
