Looks like it's either Dometic RM2351, RM2451 or RM2551. Unsure how to know which of these three as the Dometic manual schematics in the RV lists these three for what matches what I see at the back of the fridge.
I tested both fuses on the control board and they're ok.
I tested 12V power leaving the RV's power center and it's ok.
When the power arrives at the back of the fridge, the multimeter only shows around 2.9 so not sure if I'm testing it wrong or if there could be an issue for the 12V not reaching the fridge and I should check the cable between the fridge and the RV's power center.
