Is your freezer mysteriously icing up, leaving you frustrated? You’re not alone. Ice build-up in a freezer can be a common but annoying problem for both domestic and commercial users. In this guide, we’ll explain why your freezer is icing up and what you can do to fix it. Whether you’re a home user or manage a commercial kitchen, this guide has you covered.
What Causes a Freezer to Ice Up?
There are several common reasons your freezer may be icing up. Understanding these causes can help you take the right steps to fix the problem.
1. Faulty or Worn Door Seal
A damaged or worn door seal is one of the most common causes of ice buildup. If the seal is not sealing properly with a tight fit, warm air can enter, causing frost to form.
How to Check: Close the freezer door and inspect the seal for any visible cracks, gaps, or signs of wear. A simple test is to place a piece of paper between the door and the seal. If you can easily pull the paper out, the seal is likely failing, and this is a pretty sure sign that it’s time for a new seal.
2. Incorrect Temperature Settings
In the same way that fridges have a correct temperature, freezers do too. Your freezer should maintain a temperature of around -18°C. If your freezer is set too low, excess moisture can turn into frost.
How to Fix: Use a reliable thermometer to check the temperature and adjust it to the recommended setting.
3. Frequent Door Opening
Constantly opening the freezer door allows warm air in, which quickly turns to ice. This is especially common in busy commercial settings.
Solution: Be mindful of how often the door is opened and ensure it is closed properly each time.
4. Blocked Vents
Vents allow cold air to circulate inside the freezer. If these are blocked by food items, it can cause uneven cooling and ice build-up.
How to Fix: Rearrange items to keep vents clear.

Now that you know the common causes, here’s how you can fix the issue in more detail:

- Minimise Door Opening: Limit how often the freezer door is opened, especially in busy commercial environments. Make sure the door is closed securely each time. Consider installing a self-closing mechanism for commercial freezers to prevent accidental door openings.
- Clear Blocked Vents: Regularly check that the freezer vents are not obstructed by food items. This allows for proper air circulation, maintaining even cooling and preventing ice build-up.
- Clean and Maintain Your Door Seals: Regularly clean the door seals with a mild detergent and warm water to remove dirt and debris that can weaken their seal. For ongoing maintenance tips, check out our blog and video guides.
