A simple but effective way to test if the display or ribbon cable for a Dometic MES fridge is broken. It can also be used as a simple way to run or test the main PCB without the display or on the bench.

It is a fully functional, mini, display. You can see the RUN and ERROR lights, control the temperature up and down, change modes and see the normal display characters.

If you have a problem with your fridge operation and fit this to the main PCB and everything works it indicates that you have a problem with either the display PCB or ribbon cable. You can buy a new display board here and ribbon cable here. Note that the ribbon cable only works with the Apuljack Display because the original is non replaceable.

Alternatively, you can test the main PCB out of the fridge by giving it power and connecting this Test Display board.

Another use is for owners to keep in their drawer in case of emergencies so they can still run the fridge if the display or ribbon breaks.

Fitting is super easy, simply unplug the 10 way display ribbon from the main PCB, and plug the Test Display board connector in its place with the purple circuit board pointing towards you.
