# What to Do With a Full Freezer Before a Hurricane

## Days before: make it full and make it colder

**How long will food keep in freezer power outage** conditions depends mostly on what you did in the days before it, so start there.

**Fill the gaps.** A full freezer holds safe temperatures for roughly twice as long as a half-empty one, because frozen mass holds cold and air does not.

Containers of water are the cheapest way to do it. They freeze into thermal mass, they cost nothing, and afterwards they are drinking water — which in a serious outage matters more than the food did.

**Turn it colder.** A day ahead, set the freezer to its coldest. Starting the whole load several degrees lower buys real hours at the other end.

**Freeze bottles for the refrigerator.** A fridge holds about four hours on its own. Frozen bottles moved across when the power goes extend that meaningfully.

## Hours before: decide what you will need

Move anything you actually want during the outage — drinks, ice, whatever the children will ask for — into a **cooler**, before the power goes.

The point is not convenience. It is that every time somebody opens the freezer "just to grab something", hours come off the 48.

## During: shut, and stay shut

- **Full freezer: about 48 hours.**- **Half-full: about 24.**- **Refrigerator: about 4.**

Every one of those numbers assumes the door stays closed.

Do not add warm items. Do not check on it. If the outage is going to be long, **dry ice on top of the packages** buys real time, and a friend with power buys more — both are hour-two decisions rather than hour-twenty ones.

## After: read it before you clear it

This is the part that belongs to this make, and it is the reason an owner here is better off than an owner of almost anything else.

If the **power-failure light** is lit, the appliance is telling you the freezer got warmer than it should have. **Touch the alarm icon** and it will display the highest temperature the compartment actually reached.

That number decides everything:

- **still at or below 40°F, ice crystals present** — refreezable, with some loss of quality;- **above 40°F for more than two hours** — throw it out.

Read it **first**. Clearing the alarm is what most people do on instinct, and the number goes with it.

## And the beeping is not a breakage

A cabinet alarming after the power comes back is a cabinet that noticed, recorded and reported. That is the feature working. Nothing needs repairing, and nothing needs to be switched off at the breaker to make it stop — the alarm icon does that, once you have the number.

## The built-in question nobody asks until the day

Almost every hurricane checklist assumes a freestanding appliance you can reach behind, unplug and move. Every freezer in this line is a fully integrated column in kitchen joinery, and several are one half of a Side-by-Side pair. Two practical consequences follow, and both are worth settling before the storm rather than during it.

The first is that "unplug it" is not a five-second job here, and generally should not be done at all: an appliance left shut and unpowered keeps its contents far longer than one that has been opened to reach a plug. Leave it closed.

The second is that a pair behind matching doors is two appliances with two sets of contents. The refrigerator half loses its margin in hours; the freezer half holds for far longer. If you are going to open anything during an outage, know which door is which before the lights go out — and if there is a generator in the picture, know which of the two is worth the fuel. It is the refrigerator, and it is not close.
