Are there 2 x fuses linked to your fridge on the BCA ? 12v habitation fuse board , if so , are they both ok ?

Are red and black wire for 12v operation with engine running?

The Thetford N3000 troubleshooting guide (error 12 ) suggests that if you check the communication 4 x way connection on the power board there should be +/- 5v between the white and green cables with the same readings at the display board white/green . If you do not get these readings it says it could be a faulty power board or connection cable between the power board and display , so this could be worth checking.

Check high current feed and d+ at the plug on the pcb with the engine running
