A refrigerator includes a controller for regulating temperatures established in a fresh food compartment and a freezer compartment of the refrigerator. The controller is selectively operable in a temperature guard mode providing a warm temperature alarm setting function and a lower interrupt setting function. When the warm temperature alarm is active, the controller monitors temperatures of each of the fresh food compartment and the freezer compartment. If either temperature exceeds a respective predetermined value for a predetermined time, an alarm is activated to indicate a warm temperature, condition. When the power interrupt alarm setting is selected, the controller senses an interruption and restoration of power. Once power is restored, if a temperature of either the fresh f'ood compartment or the freezer compartment has exceeded a respective predetermined value, an alarm is activated to indicate an over-temperature condition. In addition, a high temperature value and an actual temperature value are displayed.
