Why is there condensation on my freezer door?

When you realize the freezer door is often covered in condensation, you might want to check if the following are the causes behind this phenomenon. There might be more than one of the reasons mentioned below:

door opened Frequently and for long

The freezer in your refrigerator is the coldest part, and it needs to stay like that. When the door is opened for long, it makes the freezer work overtime. The compressor will overheat and shut off to cool down. Once the compressor isn't running, the freezer will become warmer.

The compressor fails completely when it gets overheated. Newer refrigerators will probably shut off on their own when the door is left open for too long. Sometimes you may find that the freezer door won't shut properly when the freezer is too full.

Worn out freezer door gasket

The gasket mustn't allow the warm air from outside to penetrate into the freezer. The gasket is a rubber sealer that runs along the perimeter of the freezer or refrigerator doors. It must always be in good order.

Check to see if the gasket is ripped, crumpled, or it has come off. This will cause your fridge not to work efficiently. A broken or leaky gasket will cause excess moisture build-up in the air outlets and door.

High Outdoor Temperatures

You might see some condensation on the freezer door when the weather is very hot. The hot air condenses when it comes into contact with the cold freezer door air. The moisture isn't a lot and it quickly evaporates.

This shouldn't be a cause for alarm because, when the temperature drops, there will be no more moisture. Sometimes the temperatures in the house could be raised by cooking for a while. The warmer air in the room will cause the freezer door to sweat. Wipe any excess moisture on the fridge after cooking.

freezer set to very cold

You will notice ice build-up when the freezer is set to too cold temperatures. Too much frost won't allow the cold air to circulate properly in the freezer. When the cold air escapes through the door, you'll see the sweat on the door. This isn't good for the freezer.

energy saving mode

The energy-saving mode switches the heater, which cools the fridge, off. The warm air in the fridge will condense at the door mullion. You will also see moisture on the outside of the freezer door. It isn't wise, however, to use the energy-saving mode on hot days. It may affect the efficiency of your fridge.

Avoid opening your freezer door frequently for long periods. Keep the door locked when you don't need anything from the freezer. Ensure that the doors are properly shut at any given time. Check for any dirt on the doors that might not allow the door to shut well.

The compressor in the freezer is an expensive gadget to keep replacing as well.

When you realize the problem is the gasket, make sure you replace it immediately. A leaky or broken gasket could hike your energy bills. ">Gaskets are sold independently and are quite easy to replace. You could ask for some professional help if your gasket seems complicated to replace.

Ensure that you open windows for air circulation in the house when cooking. Wipe the excess moisture from the freezer door. Place the fridge in a cool corner of the kitchen to avoid direct sunlight during the hotter months.

Don't set your fridge to energy-saving mode especially on hot days. This will save you some energy, but it won't reduce the moisture on the door. Some old refrigerator models have an exterior moisture-reducing mode. The newer models have an automatic moisture control system that doesn't need a heater.
