The power is out! What do you do with all that food you just bought from Costco!? Or what happens to the vegetables you so carefully harvested and froze for the coming year? Here are freezer tips when you have no power!
There is nothing like opening a well-stocked deep freeze and pulling out a meal you made two months ago on a busy night, or having two kinds of ice cream for sundaes, or even having a quarter of a cow ready to provide meals for your family for the year.
However, what happens to all that food when the power goes out? Or what happens when your child was digging in the freezer looking for a frozen treat and left the door open? You need to have a plan!
While many long-term food storage advocates do not support the idea of using your freezer, I do! You just need to understand the risk involved in having a freezer and what a power outage can do, and be prepared for the extended power outage and how you will plan your freezer for that eventuality. There's no point in letting all that food go to waste that you worked so hard to store - these easy, actionable tips will help!
We will talk about this in terms of
- General day-to-day freezer tips
- Preparing for a known power outage (hurricane, severe storms, maintenance work by utility companies)
- How to react if the power goes out
- What to do when the power comes back on
But before we start, let's talk about some good general day to day safety tips you should be following. This is assuming you don't already have a generator that you can hook up and not worry.
GENERAL FREEZER TIPS
- Use a Freezer Alarm - Freezer alarms help keep you aware of the status of your freezer, even if there is a blip in power that might cause a problem, or someone has left the door open when scavenging for a late-night ice cream treat. It also tracks the current temperature of your freezer, and you'll know the state of your freezer temperature once the power comes back on. This will help you make some decisions on where to go next.
- Use a freezer lock - while it might be a bit of a pain, a freezer lock helps ensure that you and your family will lock the door when not in use, which means that door is closed all the time 🙂 This is also a great tip if you store your freezer outside, as it keeps theft at bay.
- Store meats on the bottom - cold air pools at the bottom, thus it is a safer place to keep your meats from constant door opening to a power failure.
- Keep your freezer defrosted - if your freezer requires defrosting, it will run more efficiently being routinely defrosted, thus giving it a longer life and less chance of early failure.
- Wipe down your seal/gasket often - the seal that keeps your freezer airtight gets dirty and needs to be cleaned to work most efficiently.
- Vacuum your vent routinely. Not only vacuum it of any debris, but do not store items in front of it so it has proper airflow to keep your freezer working efficiently.
- Keep a freezer inventory. Not only does this keep you from standing there with the door open trying to figure out what you have and what's for dinner, but it also helps keep your home inventory running more smoothly.

FREEZER TIPS FOR A POWER OUTAGE
BEFORE THE POWER OUTAGE
Preparing your freezer for the power outage doesn't have to be scary or hard. A few steps can save you a lot of heartaches later.
Be sure to keep your freezer maintained year 'round.
Keeping maintenance current means you're freezer won't be full of 'frost', the gaskets keep the door closed properly, the vent will be able to help it run more efficiently to keep food frozen at optimum conditions, and you'll have less to worry about if the power does go out.
Stock your freezer with ice
Odds are, you have gaps in your freezer. Fill those gaps with water bottles, emptied 2-liter soda bottles filled with water, containers, water jug, blocks or bags of ice, or even dry ice.
Getting them frozen before the power outage gives you these benefits:
- Helps your freezer run more efficiently (freezers hate dead space);
- Keeps your freezer cold longer once it stops working (think gigantic cooler);
- Allows you to have extra ice should you need it;
- Gives you fresh water if your water supply is also compromised
I don't advocate just throwing loads of loose ice into your freezer as they can begin to act like the frost that may form and impede the machine from working efficiently, but if it is that or nothing and you know you're about to have a prolonged outage, do it
TIP ►► Dry ice is another way to keep the freezer cold if you have access to it. Keep it on the top shelf of an upright, or on a pan in a chest freezer, and it will help keep your food frozen.
Set your freezer to 0° F
Knowing that there will be a problem is key here - set your freezer to a colder level will give you a longer period after to keep your food safe. You can return it to your normal setting once the emergency has passed.
Keep Meats in the Bottom
Frozen meat is big, huge, solid chunks of frozen stuff 🙂 That's good for helping maintain a freezer's temperature. And since cool air pools at the bottom of your freezer, keeping your meats on the bottom helps keep them frozen longer.
TIP ►► If you have the ability beforehand, double bag those meats or place them on trays to help cross-contamination of thawed meat juices getting on the rest of your freezer products. If you already repackage in vacuum-sealed bags, you may not need to d this.
Eat the Ice Cream First
Yes, I said eat the ice cream first, and another other highly perishable foods.
It might also be a time to eat some of those Costco boxed foods that take up a lot of room (pizzas, pre-made dinners), aren't packaged for long-term storage or just make easy meals to pop in the oven while you prepare your home for the storm coming. Replace those with bottles of water or bags of ice.
You can even dehydrate those bags of frozen vegetables to make more space for water bottles for insulation, plus give your extended pantry a boost in inventory!
FREEZER TIPS DURING A POWER OUTAGE
Don't Open the Freezer
What's the very first thing you want to do when the power goes out? Turn on the light, right? Our inclination is the same when it comes to the freezer. Resist that urge - do not open your freezer.
Chest Freezer: With a chest freezer, cold air pools at the bottom, leaving the top of the freezer warmer. If you open the freezer, you'll introduce that warm air blanket to your freezer that has to use up its valuable stored cold equalize the temperature.
Upright Freezer: In an upright freezer, the cold air acts like a waterfall when the door is open. It falls down and just pools out the bottom - and you've lost all that cold air.
TIP►► A fully stocked chest freezer should stay cold enough for about 48-72 hours, an upright freezer up to 48 hours unopened.
Cover the Freezer with Blankets
This is an especially good tip for chest freezers. Cover the freezer with a few blankets to help insulate it even further.
TIP ►► Be sure to leave the vent uncovered. Even though your freezer isn't working during a power outage, you don't want that vent blocked in the event of a power return.
Stock Up Your Coolers
If you can, get as much ice as possible from local stores. Go home and fill up the bathtub, the washing machine (top loading), coolers and the sink with ice. You can use them as ways to keep food cold. This is particularly a good idea for refrigerated items since they won't be able to keep their cool as long as frozen ones. It can also be a way to extend the life of some foods while you await the return of power or a new freezer if your freezer has died.
Add Ice to the freezer
If you know the power is going to be out for a while, you can extend the life of your freezer by adding ice. Block ice is best if you can get it because it will last longer, but will not insulate the way smaller ice pieces will, which will thaw faster. Dry ice can work even more efficiently than regular ice. Check with your local grocery store to see if they carry it.
Just remember..the minute you open the freezer door, you've allowed the warm air to enter, so only do this in extreme outages.
Power Outage-Tip: Throw a Party!
While we do all we can to protect our precious frozen food storage, here are a few tips of using up that food before it goes bad:
- Throw a Party! Have a neighborhood BBQ and cook all that food now!
- Can It! Even without regular electric power, if you have gas or even an outdoor propane station, you can can up those foods to save them.
- Preserve It! While you may not be able to run your electric dehydrator, consider studying up on air or solar dehydrating, fermenting, pickling (this would work for other vegetables), smoking and other means of non-electric preserving to keep those foods safe.
TEMPORARY FREEZER HACK
Not only are ice chests great temporary freezers if you're trying to save food from your freezer, but you can try this hack we did when we had to change refrigerators. Our new one was to be delivered, so we removed the food, buried it in ice in our only ice chest, and had things stacked in the sink, ready to make the transfer when the new fridge arrived.
THEN the company called to say the fridge was running late and wouldn't be delivered until the next morning. AFTER we'd gotten rid of our fridge.
So this is what we did.
We loaded our washing machine with freezer product and packed as much ice into it as we could.
Of course, a metal tub isn't a great insulator, so the items on the outside tended to thaw more quickly than we'd hoped. But it was able to help us save quite a bit of our freezer stock we couldn't fit into the ice chest, and we even were able to save a few refrigerator items as well.
This wouldn't have lasted for days for us, but if it's a temporary issue, this could be helpful for you.
FREEZER SAFETY TIPS - AFTER THE OUTAGE
Rule of Thumb -- if you still have a considerable amount of ice crystals, and the food temp is 40F or below, you can refreeze the food. You might have a change in quality, but the food is good.
If the freezer is above 40F for more than two hours, don't take a chance, throw it out. This is where the freezer thermometer (like this one) is a great idea. When you open the door, you'll get an immediate indication of the temperature of your freezer.
- Foods on top of your freezer may be affected more than those buried, so do a little checking top down for quality.
- Get a freezer thermometer to be able to test the temperature of the freezer if you can't see visible signs of ice crystals.
- Use a digital probe thermometer to test particular foods. It will have to go into the food and puncture your wrapping. You can then wrap with some plastic wrap to protect the small hole.
What about using the Quarter in a Cup of Ice Tip?
There's a tip that I've even suggested - to a cup of water into the freezer and freeze it, and then put a quarter on top. Freeze another quick layer of water on top to keep it in place.
If you've lost power and your freezer thaws, the quarter would theoretically be at the bottom of the cup and you'd know your food is compromised.
However, that might not work out as well as you'd hoped because water can thaw on the outside of the cup, but keep a core ice block intact. which means it floats. And unless the whole of the cup melts, that quarter may stay on top of that ice block.
And then if the power is restored, your freezer kicks back in, and the cup freezes again, that quarter is STILL on top. But how are you to know that there is a problem? You might have food that has thawed, spoiled, and then froze again.
Another issue is that the density of ice is more than the density of a bag of frozen strawberries. They are going to thaw much faster, especially if they are at the top of the freezer compared to being buried and surrounded by much more frozen items to help insulate.
So it can be a tool, but don't rely on it. Obviously, if it's at the bottom f your cup, you KNOW...but if it's still on top, but you suspect there's been an outage, do a little more investigation. I'd say your container of ice cream will tell you a lot more!

When in doubt, throw it out!
FREEZER TIPS IF YOU'VE BEEN AWAY
- If you have been away from home, and the power has been out for a few days, don't assume your food is okay to eat. Find out from your neighbors or city how long the power was out. If your power came back and refroze your food, you may not be able to tell how long it was in the danger zone.
- If you are unsure about the safety of the food you've pulled out, or you've also experienced a flood that went into your freezer, just throw it out.
Tip ►►: Don't waste fruit and vegetables that you have to remove from your freezer - throw them into your compost pile!
