Even with a superior airflow system, a refrigerator or freezer will be colder at the bottom. Warm air rises, so the upper shelves will always be slightly warmer than the lower portion of the unit.
Cold air sinks, so it collects at the bottom and, in a fridge freezer, the bottom shelves will be coldest.
The Coldest Spot: The rear center is the coldest spot in a freezer. This is the place to store your ice cream maker's canister so it's thoroughly frozen and ready for the next batch of homemade ice cream!
Bottom. Cool air tends to move down, so it's best to to buy bottom freezer as the cooling will be stored more efficiently and it'll not lose it's air. A top freezer wastes a lot of cooling when it is opened.
As the liquid refrigerant heads from the small metering tube into the larger evaporator, its pressure drops suddenly, causing it to convert back into a low-pressure vapor. The evaporator also absorbs the heat, which leads to a freezing cold vapor that keeps the unit's temperature cold enough for freezing your food.
WHY IS MY FREEZER ONLY FREEZING AT THE BOTTOM OR AT THE TOP? If your freezer is overcrowded with frozen food, it may be blocking the evaporator fan and hindering the circulation of proper airflow. This can cause fluctuations in freezer temperature.
Turn knobs to lower numbers for warmer temperatures and to higher numbers for colder temperatures. The setting of 5 for both the fresh food and freezer section is the recommended setting for most environments.
Higher Cost
One of the biggest drawbacks of a bottom freezer fridge is these models tend to cost more than freezer-on-top models. If you choose a bottom-mounted freezer refrigerator with French doors, you can expect an even greater cost.
As hot air has lesser density than the colder air and rises above, the freezer is kept at the top section, so that hot air from downward section can rise to the freezer and gets colder. This is an example of convection process.
The freezer should be between 0 and 7 degrees Fahrenheit. Since the cold air coming into the fresh food section originates in the freezer above, the rear of the top shelf will be the coldest spot in the fresh food area. Avoid placing delicate items that freeze easily on the back half of this shelf.
Store ice cream in the main part of the freezer. Do not store ice cream in the freezer door, where ice cream can be subject to more fluctuating temperatures since the door is repeatedly open and shut. Keep the ice cream container lid tightly closed when storing in the freezer to reduce the formation of ice crystals.

Bananas grow in hot climates, so they are unused to the cold. If they're kept at a cold temperature, the enzymes that enable them to ripen are inhibited. And as those enzymes become inactive, other enzymes operate more efficiently. Some cause cell damage, while others (browning enzymes) cause the skin to blacken.
The best setting for the fridge is 3°C (37.4°F) and for the freezer temperature is -18°C (-0.4°F) to -20°C (-4°F). However, this will vary depending on the types of food and produce stored in the fridge.
Refrigerator Storage: Refrigerate eggs at 40°F or less. Store them in their original carton on an inside shelf and away from pungent foods. The temperature on an inside shelf remains more constant than one on the door, which is opened and closed frequently.
Even with a superior airflow system, a refrigerator or freezer will be colder at the bottom. Warm air rises, so the upper shelves will always be slightly warmer than the lower portion of the unit.
Energy Efficiency Winner: Top FreezerIn general, top freezers are more energy efficient than bottom freezers. The reason goes back to the original freezer design which featured a top-mounted compressor.
Freezer frosting can be caused by a variety of factors, including temperature fluctuations, air drafts, and humidity levels. When warm, moist air enters the freezer, it turns into cold water droplets that freeze on contact with the walls and shelves of the freezer.
Bottom Freezer refrigerators generally offer more storage and organization options compared to Top Mount models. The pull-out drawer design of Bottom Freezers makes it easier to see and access stored items without having to reach over or dig through a single shelf.
How cold is a deep freezer? When considering freezer vs deep freezer temperature, keep in mind that deep freezers get as cold as a standard kitchen fridge freezer: 0 degrees Fahrenheit (or -18 degrees Celsius). Setting your freezer temperature too low may result in frost covering your food.
Avoid Heat Sources: Place your fridge freezer away from radiators, ovens, and direct sunlight. These heat sources can negatively impact the appliance's performance and safety. Ensure Adequate Ventilation: Leave sufficient space around the fridge for proper air circulation.
Dusty condenser coils can't release heat efficiently. Cleaning them can improve your freezer's ability to cool. First, unplug your freezer. Move the unit away from the wall, then use a vacuum or brush to clean the coils, which are usually on the back of your unit or its side panels.
Is a Full or Empty Freezer Better in a Power Outage? This much isn't really up for debate. The more cold food is in your freezer, the colder it will stay if the power goes out.
Keep the freezer well stocked.
When the freezer has little or no food inside, it has to work harder to maintain the consistently low temperature needed to create ice. Strive to keep the freezer at least half-filled, stocking it with water bottles as necessary to add more bulk.
