In most refrigerators with separate freezer and refrigerator compartments, the temperature control knob or dial typically affects the temperature settings for both sections. The single knob controls the overall cooling system of the refrigerator, including the freezer and refrigerator compartments.
When you adjust the temperature control knob, it regulates the operation of the compressor, which is responsible for cooling the entire appliance. As a result, the temperature changes will affect both the freezer and refrigerator compartments simultaneously.
However, it's worth noting that some modern refrigerators may have more advanced temperature control systems that allow for independent temperature settings between the freezer and refrigerator compartments. These models may have separate controls or digital displays that enable you to adjust and set different temperatures for each section.
If you're uncertain about the temperature control functionality of your specific refrigerator model, it's best to refer to the user manual or contact the manufacturer for accurate information regarding temperature control and settings.
