Dometic fridge stopped on electric

[Clkr]

Our Dometic fridge in our 2021 e19 doesn’t want to work on electric after the long winter hibernation. On propane it works fine. Manual says to check fuse. Problem is I can’t figure out how to remove the darn plastic cover and the diagram makes no sense. Please tell me how!! And yes, I did remove the little screw!! Many thanks

Where the lower decal says J10 if you look back down the side of it you see a place you stick a flat blade screwdriver, and push the screwdriver to the left slightly to disengage the plastic catch, just as the illustration shows.
