Is your freezer too cold? It could cause you a lot of trouble. Here are 5 tips for you to check this. 

Freezers solve so many problems, that our every day lives would be much different without them, and yet, we fail to pay enough attention to them.

This begs the question, what can happen if you let your appliance get too cold?

It might be counterintuitive to consider that a machine designed to operate at subzero temperatures could sustain damage from it getting too cold, but it can definitely happen.

In fact, depending on how drastic the temperature drop is, you could experience a myriad of issues, ranging from damage to your food, to complete appliance malfunction.

If you’ve noticed your unit has been having operating issues, or have simply spotted more ice inside the chamber lately, there’s a very good chance your machine needs urgent checking.

I was in your position not too long ago, so trust me when I say that I get how frustrating this is. In order to fix my situation, I had to do thorough research and undergo a tedious trial and error process.

Today, I want to share my findings to help you.

Below, you’ll find a list with the most common problems you could experience from this event, and some telltale signs to look out for before it’s too late. I’m confident that, if you pay close attention to them, your freezer will be back to normal in the blink of an eye.

Sounds good? Let’s go!

Fixing a Frozen Freezer

While I strongly advise addressing this issue as soon as possible, it’s of the utmost importance to do so in a detailed and orderly manner. Troubleshooting has never benefited from going about repairs rashly, so please, bear with me, I promise we’ll get to the bottom of this.

Here are 5 signs and consequences of a freezer being too cold:

  1. Damaged food
  2. Freezer burn
  3. Condensation
  4. Frozen components
  5. Component failure

#1 Damaged Food

You can lose your food’s nutrients because of your freezer’s high temperature

I want to start off this list with the “least concerning” consequence of this event.

When your freezer gets too cold, your food could be damaged and lose a big part of its nutrients. This also happens when you overcook your food, as the particles inside it are destroyed, causing the loss of macronutrients (protein, fats & carbs).

This is the more severe evolution of the point below, since freezer burn is only partial, and we’re talking about total loss here.

That being said, if you think about it, this is the most “desirable” symptom of a frozen freezer. Sure, spoiled food is always a tragedy, and given the cost of groceries these days, a hard hit to your pocket as well.

But unless you love frozen exotic delicacies, restocking your freezer will never be as expensive as replacing a broken component.

As soon as you identify this condition to be present, make sure to get some ice, a portable cooler, and relocate your frozen goods inside it temporarily. This will prevent further damage to your groceries, and allow you to address the temperature problem more comfortably.

#2 Freezer Burn

Ever heard of frostbite? Turns out your food can get it too

Assuming it’s not too late, and your food is just beginning to sustain freeze damage, there are many things you can do to save it.

Storing food in the freezer is a great way to extend its lifespan; however, even when everything in the appliance works normally, it could cause freeze burn on your groceries if you don’t cover them up properly.

I’m telling you this because it would be easy to confuse normal freezer burn with that resulting of dangerously low freezer temperatures.

If you’re in the habit of storing your groceries inside Tupperware, or tightly enclosed in saran wrap, your food should not get damaged. If it does despite it being adequately protected, your appliance is, in fact, likely too cold.

This is optional, but you can always go online to find some useful information that can help you protect your groceries from freezer burn, even after you’ve resolved this issue.

#3 Condensation

Excessive ice buildup can lead to dangerous amounts of condensation

You probably had never thought about this before, but condensation can also be a big problem for your freezer.

Have you ever noticed how your appliance starts leaking when there’s a massive blackout? This is mainly due to the ice collected in and around your freezer’s chamber and internal components, which melts down after a couple of hours at ambient temperature.

If you only experience leaking, you’re not out of the woods, but it’s certainly much safer than having condensation present.

Depending on where you live, heat in the environment could start condensing the water from the melted ice in and around the freezer’s parts.

And while this can happen in fully-functional freezers as well, more ice means more water to be condensed later on. If you notice the amount of ice in your freezer’s chamber increases by the day, there’s a very good chance it’s too cold, which could cause a catastrophe in the event of a long blackout.

#4 Frozen Components

Your freezer’s components could have trouble working normally under low temperatures

It’s not the most logical thing to consider that your freezer’s components could be damaged by extremely low temperatures, yet, it’s an undeniable truth.

Most parts of an appliance are designed to operate under certain temperatures. If, during operation, the safe limit is exceeded, you can start experiencing a myriad of issues, ranging from a slight malfunction, to total failure.

Some components inside your freezer, such as the compressor, the thermostat, or the refrigerant tubes, can be negatively impacted by freezing.

This is a problem that also affects AC units, and many more appliances.

If your freezer worked just fine and all of a sudden it started showing signs of malfunction, it would be a good idea to check for excessive icing on the chamber, or freezer burn on your groceries.

When these events manifest themselves, you might already be in trouble, which is why it’s of the utmost importance that you address this issue immediately. Failing to do so, could result in costly repairs and dangerous malfunctions.

#5 Component Failure

Lastly, let’s talk about the most severe consequences that could result from a frozen freezer.

As stated above, your appliance’s components have been specifically designed to operate at certain temperatures. Using your unit below these limits can cause some inconveniences in the short term, and expensive faults in the long run.

Your compressor, for example, which is the part responsible for transporting the refrigerant all over the machine, could freeze up, and struggle to do its job. This puts an enormous amount of unnecessary pressure on it, and decreases its lifespan significantly.

While it might seem that a freezer that’s too cold is not that big of a problem, it certainly can be. It’s crucial that you address the issue as soon as you detect any of the signs mentioned above.

The quicker you act, the less severe the fallout will be.

When Should You Call a Pro?

The answer to this question will depend greatly on the status of your warranty and whether any of the solutions above worked for you.

If you are still under coverage and don’t mind waiting a couple of days or weeks for your manufacturer to send a technician to your home, by all means, go ahead and give them a call.

Unless specified otherwise on your documents, they should take care of the repairs for free.

Assuming your warranty has expired, you’ll have to get some quotations on the parts you suspect have been damaged by this problem. Once you have them, look for an experienced technician who can help you install them.

I know it’s annoying having to pay for repairs, but using your freezer while it’s too cold, will keep creating problems until you fix the situation.


Thinking that a freezer being too cold can cause problems, is not the most logical thing. However, as you’ve learned in this piece, it can certainly be the source of numerous inconveniences.

That being said, I hope I’ve shed enough light on the matter to help you identify whether this is your issue, so you can address it as soon as possible. Be sure to check our other article, where we discuss what the culprits to this situation can be, and the simplest ways to fix them.

Act quickly, and, if possible, keep a portable cooler handy at all times to preserve your groceries in case you need to clear the freezer’s chamber.

Trying to do your own repairs is something I always applaud, but if you ever feel doubtful during the process, please do not hesitate to call a technician.
