/diy/ - Do It Yourself

>I noticed that eventually it says the fridge and freezer are at the target temperatures of 2 degrees and -16 degrees respectively but then when I reset it, it will read a different temperature.

WTF kind of crazy european fridge do you have? That sounds like some sort of computer controlled shit right there. This here is the extent of the controls on my Kenmore 14. An adjustable bimetallic thermostat that turns the compressor & fan on and off. (inb4 clean your fridge)

So how warm does it get before it kicks on again? For a new-ish, well insulated fridge, it's not out of the ordinary for the compressor to stay off for hours at a time if the doors have not been opened. It's possible that there's actually nothing wrong, and that the temperature display just only updates a few times an hour. A temperature variation of 5ºf between compressor shut-down and start-up is almost typical, you might just be expecting too precise temperature control out of this appliance.

Do this experiment: Wait for the compressor to shut off, and then prop the door open for a few minutes. See how long it takes to turn back on once all the cold air is let out. It should cycle back on within a minute or two of having the door wide open. If it does, there's nothing wrong.
