So I called Vitrifrigo America LLC 954-979-7737 talked to the manager
and he stepped me through the debug process

Fan Test
1) disconnect the fan the compressor should now run - faulty fan
-disconnect fan red power from piggy back jumper on the main terminal +
-disconnect fan black negative from terminal F

- supply power direct to fan 12v +, & ground to fan black, fan should turn

Thermostat test
2) disconnect the thermostat the compressor should now run - faulty thermostat
-disconnect thermostat wire from terminal C
-disconnect thermostat thumbnail circuit piggy back board from terminal T
-jumper Terminal T and terminal C

Compressor test
3) if test 1 and 2 fail to start compressor - possible faulty compressor

Comprehensive tests
4)A 10mA light emitting diode (LED) jumper can be connected between
the terminals + and D. err flash every ,25s then stop for 4s then repeats
Flashes
5-electronic control unit faulty
4-minium motor speed error
3-motor failed to start
2-fan over current cut out

I would make very sure that you have 12+ volts at the fridge while trying to start the compressor. The logic board of the fridge has a low voltage detection shutdown for the compressor. The inside light will work even if the logic has disabled the compressor due to low voltage. Try connecting a battery charger to the battery while trying to start the fridge.
