Remove outside lower vent/access cover
There is a 12V DC terminal Block to the right of control module (lower left corner)
12V POS and 12V NEG leads are connected to that terminal block
Check for 12V DC on those leads/connections.
NO DC then MAIN DC Fuse for fridge circuit is bad
Got 12V DC at terminal block
The 12V DC POS lead goes to a t-stat installed on burner stack (Dometic Recall---your model is included in that)
12V DC POS goes to and then back from that t-stat to control module
IF that stack temp t-stat is tripped ....NO DC\
It has a manual reset button in center of it
Reset if tripped and you should have DC power....display panel lights on
etc.
But if tripped it could mean fridge is DEAD. It trips due to HIGH Temps...usually due to bad cooling unit
If not tripped..then need to remove control module cover and check if 3A fuse on circuit board has blown
