To check whether a GE refrigerator is set at the ideal temperature, locate the control inside the refrigerator, directly above the fresh food section, and press the plus or minus button once. This displays the temperature settings of both the refrigerator and the freezer compartments.
As of 2015, GE refrigerator models have three different control types, all of which display different readings. According to minimum safety requirements, fresh food should be stored at a temperature between 34 and 45 degrees Fahrenheit and frozen food should be stored between negative 6 and 6 degrees Fahrenheit.
On a GE refrigerator model with two controls, the ideal temperature is represented by 5 and C or 5 and 5 on the display. A GE refrigerator with a single control displays the ideal temperature as 5. Models that feature electric controls display the ideal temperature as a digit between 0 and 37.
To change the temperature setting on a GE refrigerator, simply press the plus or minus button for every degree change desired. It is also possible to change the display from Fahrenheit to Celsius or vice versa by pressing once on the display mode. After you adjust the temperature, it can take up to 24 hours for the temperature to stabilize.
