Freezer's work at their most efficient when at least 75% full. The less space available, the less the freezer has to do to keep the temperature down. a good thing. Overfilling the freezer can block air vents, restrict the flow of cold air, and overtax your refrigerator's condenser, which could lead to a burn out.
Yes, a freezer that is too packed can potentially stop the ice maker from working properly. Here are a few reasons why this might happen: Airflow Restriction: Freezers rely on proper airflow to maintain temperature and function effectively.
Excessive amounts of food inside can block the flow of air from the vents, which means your condenser and refrigerator motor have to work harder to maintain the set temperature. This, in turn, causes burnout of various parts of the unit.
Storage tip: Keep your freezer full, but not packed. Keeping your freezer around 75-80% full helps retain cold air. If the freezer is fully filled, food may block the internal air vents, making it harder to distribute cold air throughout the freezer.
While a full freezer runs more efficiently than an empty one, overfilling it can potentially block the air vents.

Consider that 1 cubic foot of freezer space will hold approximately 25 lbs of food, depending on the item. A 7 cubic foot freezer may accommodate around 175 lbs of food. This is a smaller freezer size and would be a good choice for overflow items that won't fit in your refrigerator's freezer.
The water from the melted frost will run down a drain tube and into a pan under your freezer where it naturally evaporates back into the air. However, when the defrost system fails it can allow frost and/ or ice to form inside your freezer making a mess and affecting the effectiveness of the machine.
An excessive amount of food in your compartments and freezer blocks the vents, which affects the airflow within the unit and increases its temperature. This causes the motor to work harder than usual, which can affect your energy consumption and overall refrigerator efficiency.
This ensures any bacteria present in the food will not grow and multiply, keeping the food safe to eat for longer periods of time. However, most freezer manufacturers recommend keeping the appliance between 0 and 5 degrees Fahrenheit for optimal performance.
Overloading can cause big temperature fluctuations as it restricts the airflow inside the freezer. This can lead to uneven cooling and compromise the safety and quality of your frozen food.
In general, freezer burn is caused by water evaporating from the stored food item and can most easily be prevented by tightly wrapping your food, removing as much air as possible. While flavor and texture will undoubtedly suffer when food has been freezer-burned, it is still safe to eat.
Their representative told us: “A freezer full of food should maintain its temperature better than an empty one”—with “lower temperature fluctuations when the door is opened.” As they explained, though: “[Y]ou also need to get that food cold in the first place, which will take a lot more energy than cooling air.”
However, if your freezer is cold but not freezing, it may be time to inspect the thermostat. Try changing the thermostat from the lowest setting to the highest setting. If you don't hear a click sound, then a professional replacement is recommended.
Discard heated leftovers. Thawed cakes, biscuits, breads, fruits and fruit juices are okay to refreeze once if no strong 'yeasty' smell. Thawed snap frozen meat, poultry or fish is okay to refreeze if still below 4°C or transported and handled safely and spent less than 2 hours in temperature danger zone.
The majority of the energy your freezer uses goes towards cooling down the air that comes in when you open the freezer door. When your freezer is full, there is less room for warmer air to take up, and the items that are in there help to cool down any air that does sneak in. So keeping it full means less energy used.
The Dangers of Fridge Overfilling
If your fridge is stuffed too full of food then it's not going to work efficiently. Sometimes you need to cram food into every nook and cranny you can find inside the fridge (particularly at Christmas time), but this means that the airflow is blocked.
To store frozen foods at best quality, keep the freezer set to maintain zero (0 °F or -17.8 °C). Some combination refrigerator-freezers cannot keep the freezer air that cold.
Defrosting the freezer and cleaning it regularly helps keep ice at bay. Once the freezer is defrosted, clean it using a warm water and baking soda solution to remove food particles or liquids and limit ice formation. Also inspect the condition of your door seals, and replace them when they wear down.
It is recommended that a 4-star freezer needs to operate at -18 degrees Celsius as a minimum. This will prevent bacteria from growing and will keep your frozen food fresher for longer. Whilst it is recommended to keep your freezer below -18 degrees Celsius, it is important to not drop the temperature too low.
A freezer will run more efficiently when full. This is because it doesn't have to work as hard to cool down the internal temperature. It is therefore cheaper to run a freezer that is full.
If your freezer is only half full, we recommend filling it up with water bottles or ice packs to fill the gaps.
