Converting a freezer to a refrigerator by simply increasing the freezer's temperature to above freezing is not recommended and generally not feasible with standard household appliances. Freezers and refrigerators are designed with specific temperature ranges and components optimized for their respective functions.
Here's why it's not advisable:
Temperature range: Freezers are designed to maintain temperatures below freezing, typically between -18°C to -23°C (-0.4°F to -9.4°F), to keep food frozen and prevent bacterial growth. Refrigerators, on the other hand, operate at temperatures above freezing, usually between 2°C to 4°C (36°F to 40°F), to keep perishable items cool.
Food safety: If you raise the freezer's temperature above freezing, the food inside will start thawing, and it will no longer be safe to store frozen items. The risk of bacterial growth and food spoilage will increase significantly.
Cooling capacity: Freezers are designed with more powerful compressors and cooling systems to achieve lower temperatures compared to refrigerators. Even if you were to adjust the temperature setting, the cooling system may not be able to maintain a stable temperature within the desired refrigerator range.
Energy efficiency: Running a freezer at a higher temperature than its intended range can lead to inefficient energy usage, as the compressor may have to work harder to maintain the elevated temperature.
If you need additional refrigerator space, it's best to consider purchasing a dedicated refrigerator designed for that purpose. There are some standalone refrigerators available that can be used as backups or for extra storage when needed. Alternatively, you could invest in a combination fridge-freezer, which comes with separate compartments for freezing and refrigeration.
Always consult the manufacturer's guidelines and specifications for your appliance to ensure you are using it safely and efficiently. Attempting to modify an appliance beyond its intended use can lead to problems, reduced lifespan, and potential safety hazards.
