A sensing and display system for a refrigerator includes a plurality of sensors which are sequentially monitored at a first rate in order to determine whether certain conditions in the refrigerator are within predetermined ranges. If the sensed conditions are within their ranges, a first plurality of visual indicators are sequentially energized at a second rate and a separate indicator is continuously energized to indicate normal operating conditions. If the system detects that one or more of the sensed conditions are not within their ranges, the first plurality of indicators and the separate indicator are de-energized, and one or more of a second plurality of indicators are energized to inform the user of the existence of one or more abnormal operating conditions. The system delays an abnormal condition indication, such as an overtemperature condition, until the condition has existed for a predetermined period of time. The system also provides separate and distinct indications for a presently existing overtemperature condition and a previous overtemperature condition which has since disappeared.

In a refrigeration apparatus having means defining a refrigerated space and cooling means for cooling the air within said refrigerated space, a sensing and display system comprising: display means including an electrically energizable visual indicator; sensing means connected to said refrigeration apparatus and arranged to provide a signal indicating a predetermined operating condition of said apparatus; and, electronic signal processing means coupled to said display means and to said sensing means, said signal processing means including means operative at a first rate and responsive to said sensing means for repetitively determining in a continuous manner during an interval whether said predetermined operating condition exists and means operative at a second rate slower than said first rate for energizing said indicator to indicate that said predetermined operating condition exists.
