How To Fix Ice Build Up in Your Freezer

Aug 28, 2019 | Bosch News, Bosch Refrigeration, News

Ice building up in the fridge or freezer can be a serious problem as it can keep the temperature in the appliance too hot, which could potentially end up making your food go off or there could also be unpleasant and unwanted odours. If your freezer is under warranty it is important to call a technician to help you as if you fix the appliance yourself you could void the warranty. There are a few things you can check yourself to fix the issue. We have created a list of a few checks you can do yourself at home if your appliance is not under warranty.



​You could reduce the amount of times you go into your freezer every day. Each time you open your freezer door the cold air would flow out and warm air will find its way inside. This humidity in the warm air is the most common cause of frost build up in the freezer. Humidity can also be introduced into the freezer when you put hot foods into it. You should always wait until your food is cool before placing it into the freezer this will stop moisture from forming and will prevent frost. Place hot food in your refrigerator and allow it to cool down to room temperature before placing it into your freezer for good. Bosch’s built-in SuperFreezing function is a feature designed especially to prevent defrosting and is commonplace in many Bosch freezer units. Engage the SuperFreezing mode when you add new food to the freezer will stop any temperature increases or defrosting. It means that your food will stay fresher and flavoursome for longer!


​Setting your freezers temperature too high or too low can cause excess ice to form and build up quickly. To prevent ice from building up it is a very good idea to check your freezers thermometer. The temperature of your freezer should be set to -18 degrees. To keep an eye on this keep a thermometer inside the freezer and check the temperature every month.

Keep It Closed

​When you go into your freezer most of the time you don’t know where anything is, which means the door is left open a lot longer than it should be. If you organise your freezer with labels you will easily be able to find what you want which will shorten the time with the freezer door open.

You should also take time to check the seal on your freezer door. Your freezer door should create an airtight seal when it is closed, however, if the seal is broken it may be allowing warm air to flow in and out of the freezer. This air will cause ice to build up in your freezer very quickly. Also ensure the food in the freezer isn’t blocking the door from closing as well as check for any cold areas around your fridge where there could be a space.

Doors being left ajar is a commonly experience problem in many homes which led to us creating our renowned SoftClosing door technology. Freezer doors with this feature will close automatically and softly once they are within a 20 degree angle. It means that you won’t ever have to worry about whether you’ve shut the freezer door properly in passing.

Keep It Full

​More air in your freezer could mean a bigger build up of ice. Freezers that are full of food will usually have a slower build up of ice than ones that are empty. Whenever you can keep your freezer well stocked to cut out the amount of empty space. At the same time though make sure that the food you store in your freezer isn’t there for too long. Keeping food in the freezer for too long could cause freezer burn. The moisture will then create more ice, if you remove foods that have been stored for a while this will prevent frost and ice build up.

NoFrost Technology

No Frost technology will make sure that you will never have to manually defrost your freezer again. It will do this by constantly circulating cool air around the appliance, which will then prevent any moisture build up from occurring on the cabinet walls. It will also keep your frozen food fresher for longer by preventing any unpleasant tasting freezer burns, which happens when food is overexposed to oxygen.
