# How Long Food Is Safe in the Fridge and Freezer Without Power

How many hours is food safe in a fridge without power is the one question on this site where the answer matters more than any repair, and in this county it comes up every summer.

## How many hours is food safe in fridge without power? The numbers

**Refrigerator: about four hours**, with the door kept closed.

**Full freezer: about forty-eight hours.** **Half-full freezer: about twenty-four.**

A full freezer holds twice as long as a half-empty one for a simple reason — frozen food is its own cold store, and a packed cabinet has far more of it. This is why filling the empty space with bottles of water before storm season is worth doing: it costs nothing and it doubles your margin.

## The mistake almost everyone makes

Those figures assume the door **stays shut**. Not mostly shut. Shut.

Every opening dumps the cold air out and pulls warm, humid Florida air in, and in a refrigerator that air is most of what is holding the temperature. A cabinet opened three times during a four-hour outage does not get four hours — it may get two.

The instinct during an outage is to keep checking, and the checking is what spends the budget. Decide at the start what you need out of it, take that in one opening, and then leave it alone.

## Afterwards: ice crystals, not judgment

For the **freezer**, the test is physical and it is reliable: **visible ice crystals**. Anything still holding them can be refrozen safely. The texture may suffer — a refrozen loaf or a bag of berries will not be what it was — but it is not a safety question.

Anything that has thawed completely and been above forty degrees for over two hours goes.

For the **refrigerator**, the rule is time and temperature rather than inspection. Meat, poultry, fish, dairy, eggs, cooked leftovers, cut fruit and anything containing them: above forty degrees for more than two hours, discard.

What survives: hard cheeses, butter, most condiments, whole uncut fruit and vegetables, jams, and unopened shelf-stable items that happened to be in there.

## Smell is not a test

This is worth being blunt about because it is the most common thing people rely on.

The organisms that cause food poisoning frequently produce **no smell, no change in appearance and no change in taste**. The ones that make food smell bad are often harmless spoilage bacteria. So a container that smells fine can be dangerous and one that smells sour can be merely unpleasant.

Time and temperature are the test. Nothing else is.

## The trick that tells you what happened while you were out

Worth setting up once, before the next storm.

Freeze a cup of water solid. Put a coin on top of the ice. Leave it in the freezer.

If you come back and the coin is still **on top**, the freezer stayed frozen. If it is **at the bottom** of the cup, the contents thawed completely and refroze — and everything in that freezer should be treated as thawed, regardless of how solid it feels now.

It costs nothing and it answers a question you otherwise cannot answer at all.

## What the appliance will and will not tell you

On a **refrigerator**, this maker publishes a high-temperature alert — **H** or **HI** — and it does something genuinely useful: when you acknowledge the alarm, the display shows the **highest temperature the cabinet reached**. Write that number down before clearing it, because clearing it discards it, and it is the single most useful fact about what happened while the power was off.

On a **freezer**, there is nothing. This maker publishes no codes at all for any freezer it builds, so the cabinet cannot tell you anything and the ice-crystal test and the coin are what you have.

## Before the season, four things

**Fill the freezer.** Bottles of water in the empty space, frozen. They double the holding time and they thaw into drinking water.

**Set a thermometer in each cabinet now.** Thirty-seven degrees in the fresh-food section and zero in the freezer is what this maker recommends, and knowing where you start decides how much margin you have.

**Clean the condenser coil.** A cabinet that was struggling before the outage recovers more slowly afterwards, and in this territory the coil behind the floor-level grille loads within a year or two.

**Check the door seal** with the dollar-bill test. A cabinet that leaks warm air continuously has less margin on an ordinary day and much less on a hot one with no power.
