Nobody wants to open the door to find melted ice cream, defrosted meat or mushy vegetables. The window to act is small, but thankfully there are things you can do.
Many modern appliances come with a high-temperature alarm that alerts you when the freezer temperature becomes dangerously high. It's worth checking our reviews though, as we sometimes find models where this alarm, although listed by the manufacturer, didn't activate when we tested it.

The Hitchhiker's Guide to the GalaxyThere are a few things to check first before you make any sudden decisions.

If your fridge freezer has really gone to the great appliance showroom in the sky, you'll want to at least try to save its contents.
Keep the door closed while you make a plan to keep the cold in and the warmth out.
A cool box filled with ice or cool blocks, a portable camping fridge or a neighbour's fridge freezer can be used to rehome food in the short-term. Non-perishables, such as soft drinks, can be removed and stored in a cupboard for now. If your fridge freezer breaks in winter, you can keep food outside as long as it's in clean, dry conditions, out of direct sunlight and protected from animals. You should use a sealed box to prevent contamination and tampering. This is only really suitable for your fridge food, as temperatures in the UK thankfully rarely match those of a freezer.

Much like a computer, sometimes turning your fridge freezer off and on again can be enough to get it to start working again. Some higher-end models have a factory reset option on the controls panel. If yours doesn't have this, check the instruction manual for your model to see if there's a key combination you need to press to enable this.
Failing that, you can try unplugging it from the wall and waiting for the time specified in the instruction manual before plugging it back in. Wait for it to stabilise to a safe temperature before returning any food.
If that doesn't do the trick, here are some issues you might be able to fix yourself:

Fridge freezers, as well as standalone fridges and freezers, are covered by the 'right to repair' legislation in the UK, meaning manufacturers must make spare parts available for seven or 10 years after product discontinuation, depending on the part. Some parts are available to everyone, while some are only for professional repairers.
Even if none of your statutory rights apply, you might still be protected.
