Where is the 5 amp fuse providing 12 power to the display on thetford fridges

I have a Thetford N180 fitted in a Swift Fairway 530 Caravan 2008. The fridge is working on mains power and the internal light is working but neither the LCD or LED are working. The on off switch does work as the internal fridge light goes on and off as expected. As nothing is displayed it isn't possible to see whether the mode or temperature switches are functioning. Fuses F2 Fridge signal and F3 Fridge supply located on the main fuse box are both ok. I couldn't see a fuse on the pcb on which the lcd is mounted although I didn't remove the board to look at the reverse side. I am guessing that there is no 12V supply to the pcb but any suggestions would be gratefully received.

The 5-amp fuse that provides 12V power to the display on your Thetford N180 fridge is most likely located in the main fuse box. Some Thetford fridges have a separate fuse specifically for the display, but others use the main fuse for power to the display and other components.
I would recommend checking the main fuse box again to make sure that the appropriate fuse is in place and that it is not blown. If it is in place and not blown, you can check the wiring leading to the display to ensure that there are no loose connections or damage to the wires.
If the fuse and wiring are fine, the issue may be with the display itself and it may need to be replaced. If you are not confident in troubleshooting the issue, it is recommended to seek assistance from a qualified technician.

simple answer. Little resetable fuse on power board, F5 as i remember. It causes the display board to go insane as it doesn't provide enough power to the board. Solder a 2amp one across it. I nicked one from an old computer motherboard USB fuse(usually mounted next to each usb socket). SORTED! was an issue with 2007/8 fridges, especially if you had solar panels fitted tgo your caravan!!!! :)
