A replacement arrives.

Much smaller and simpler, also very pleasantly much quieter as well.

The interior lamp burnt out after about a minute of woeful service but since it's a Noah's ark style incandescent it's no big deal, I hate the things, their warm colour gives a very poor look to food, plus using extra power only leads to heat in a place that's trying to be cool.
I removed the nice LED one I had put in the old fridge freezer and pressed it into service here.
Tomorrow I'll shuffle the fridge into place.
