Freezer Burn: Causes, Prevention, and When You Need Freezer Repairs

Freezer burn — ice crystals forming on the outside of the food stored in your freezer — is a common household frustration that can impact the quality of your food. While there are many factors that contribute to this phenomenon, your freezer’s performance definitely plays a significant role, which is one reason why keeping up with maintenance and repairs is so important. 

If you’re constantly battling freezer burn on your food, keep reading to learn more about its causes, how to prevent it, and when you should seek professional freezer repairs from the experts at Appliance E.M.T.

What Is Freezer Burn?

Freezer burn occurs when frozen food is exposed to air. The moisture escapes from the food and forms ice crystals, leading to dehydration and oxidation. It can look like frost crystals inside packaging or grayish-brown or white dry patches on meat and often gives food a tough, leathery texture after cooking. 

Freezer-burned food is generally safe to eat if it has been kept continuously frozen — freezer burn affects taste and texture more than safety. However, if the food has thawed and refrozen or smells off, it’s best to discard it. 

What Causes Freezer Burn?

There are a few possible causes of freezer burn, including:

Poor Packaging

Poor packaging exposes the food to air, increasing the risk of freezer burn. If there are air pockets inside containers, the freezer bags are improperly sealed, or the packaging was not designed for long-term freezing, you’re more likely to experience issues. 

Temperature Issues

Temperature issues also play a big role in freezer burn. Ideally, your freezer should remain at 0°F — any warmer, and you’re increasing the risk of moisture loss. Temperature fluctuations — like those that happen when you leave the freezer door open, overload or underload it, the power goes out, or you open and close the door frequently — also create ideal conditions for freezer burn. 

Faulty Door Gaskets

The freezer door gasket is responsible for creating a tight seal. If it’s cracked or loose, it can allow warm air in. If you notice increased condensation or frost buildup, there’s a good chance the door gasket needs to be replaced. 

Signs Your Freezer May Be Contributing to the Problem

Freezer burn on its own doesn’t necessarily mean your freezer needs repairs. However, if it’s accompanied by other issues, it’s a good indication that it’s time to reach out to the expert technicians at Appliance E.M.T.

Be on the lookout for these issues:

• Excessive frost buildup: Look for ice on the walls or vents and frost accumulating rapidly, which indicate there’s something wrong. 
• Inconsistent freezing: If some foods are soft while others are rock-solid, there may be issues with your freezer. Ice cream is a good indicator — is it too hard or too soft?
• Loud or constant running: This may mean the compressor is working overtime to maintain the correct temperature. 
• Water leaks or ice under drawers: These may be signs that there’s an issue with the defrost drain. 

How to Prevent Freezer Burn

The right habits go a long way toward preventing freezer burn and keeping your food tasting fresh. 

• Use proper packaging: Use heavy-duty freezer bags to store your food. If you have access to a vacuum sealer, use that; otherwise, do your best to remove all excess air before closing the bag. Make sure all containers are airtight, as well. 
• Cool food before freezing: Make sure your food has completely cooled before you put it in the freezer to reduce condensation.
• Maintain the proper temperature: Use an appliance thermometer to verify that your freezer remains at 0°F and avoid frequently changing the settings. 
• Stay organized: Label and date your items. Once they’re no longer safe to eat, throw them out to prevent overcrowding. 
• Check and maintain door seals: Clean the door gaskets regularly. You can test the seal by inserting a small piece of paper, then closing the door. If you feel a bit of resistance or tension as you pull the paper out, that’s good — if not, the seal is likely compromised.
