troubleshooting my 3 Way Dometic Fridge

[RPTech1]

I am troubleshooting my 3 Way Dometic Fridge error code 06 DC relay not connected when via battery and on battery error 50 code Gas lock out 3 attempts

Some Notes
- yes checked battery connections and fuses, all good
- no gas flow problems, I disconnected the gas main line connection under the fridge and turned the gas back on, the gas was flowing without obstruction
- reset via silver knob done
- it functions as expected on 240volts (AC)
- Our van is 2.5 years old
