摘要： The self-diagnostic system for refrigerator appliance controlled by the following routine steps in a control program: a reset routine for designating input and output ports and clearing all memories upon powering up, and thereafter storing initial value into a desired memory; a timer interrupt routine for being periodically carried out every time set by the reset routine and storing an elapsed time in a selected memory; an initial display subroutine for turning on all lamps, then turning off a shut-off display lamp in a predetermined time set by the timer interrupt routine, automatically turning on a normal state display lamp and an alarm lamp, and driving a compressor in order to actuate a refrigerator; a main routine for determining whether time cycle set by said timer interrupt routine has been set and executing a plurality of routines detecting malfunction of the appliances and alerting the user to the occurrence of the malfunction.
