In most standard home refrigerators, the freezer and refrigerator compartments share a common cooling system, but they are designed to maintain different temperatures. The freezer is meant to be colder than the refrigerator to keep frozen foods at the appropriate temperature. Attempting to adjust the freezer temperature to match the refrigerator temperature might cause problems with food safety and overall functionality.
Refrigerators typically have a thermostat or temperature control mechanism that allows you to adjust the overall cooling level, which indirectly affects both the refrigerator and freezer temperatures. However, you cannot independently set the freezer temperature to match the refrigerator temperature on most traditional refrigerators.
If you find that your refrigerator or freezer is not cooling correctly or maintaining the desired temperatures, it's best to consult the user manual or contact the manufacturer's customer support for guidance on troubleshooting or potential adjustments. Additionally, make sure the refrigerator's vents and coils are clean and free of dust, as this can impact its cooling efficiency. If there's a specific reason you want both compartments at the same temperature, consider investing in a dual-zone refrigerator that is explicitly designed for this purpose.
