This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
Not shelf life — the appliance. One page each for the correct fridge and freezer setting, where the cold and warm zones actually are in each design, how to check with a cheap thermometer and where to put it, what the star ratings mean, why a fridge in an unheated garage or porch fails in winter, door seals, frost build-up and defrosting, cleaning and smells, how long the contents stay safe in a power cut by appliance type and fullness, the refreeze rule, and the settings for a wine, vegetable or zero-degree drawer.
A "how long does my freezer last without power" calculator sits on top.
How to use it
Use Fridge and freezer temperatures to understand the inputs, units and assumptions before relying on an output. A useful result should be reproducible from the named source rather than presented as an unexplained score.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
