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: a plurality of sensors connected to said refrigeration apparatus, each of said sensors arranged to provide an output signal to indicate the existence of a sensed operating condition of said apparatus; a first series of electrical indicators; a second series of electrical indicators, at least one indicator of said second series of indicators corresponding to each of said sensed operating conditions; and, electronic signal processing means coupled to said sensors and to said first and second series of indicators, including means for effecting repetitive sequential energization of said first series of indicators during periods when said sensors indicate that none of said predetermined sensed operating conditions exist; and, means for terminating sequential energization of said first series of indicators and energizing one of said second series of indicators when one of said sensors indicates the existence of one of said sensed operating conditions.
