The fridge in question is not a CFX-50Dz, it is a CF50-Dz. Note the subject at the top of your page. The fridge was located in an Aussie Swag fridge box, from a late nineties model. The vent cover failed. The problem with the Waeco is the reversible lid. I did not buy a brand new fridge to have to fit parts to have to modify it to make it work. I am a carpenter not a fridge technician, but hey, thanks for the advice.
