Abstract
An input command system for an electronic refrigerator control wherein dedicated function keys are provided for inputting commands to the processor. The processor will not accept inputs from the dedicated function keys unless an enable key is pressed first. The enable key is hidden on the control panel so as to avoid unauthorized inputting of commands. Once enabled, the processor receives commands for a predetermined time period that is extended when commands are input.
