If it runs on AC but not on 12V, check the DC side. Measure the voltage at the fridge's DC input while it's calling for cooling, and check the wiring and connections from the battery. Low voltage will keep the compressor from starting. If voltage is good, the DC side of the power supply has likely failed. The thermostat seems fine, since it's switching normally.
