Sydney supplied the OEM small under port settee 12v Danfoss powered fridge/freezer in my boat,it still works. My main fridge(eutectic) is U-Tec, a replacement I`d say,same compressor supplies the freezer, in the cockpit. Neither use latches.Try asking Moorebank, they may have done your freezer, they`ve been around long enough to amass bits and pieces.
They replaced the complete power unit for my eutectics 5 years back, and were excited their 30yo. fridge still worked well.
