step one, setting entry conditions and exit conditions of corresponding special programs;

step two: after the refrigerator is powered on, the temperature control knob, the door switch signal and the power-on time are calculated and analyzed,

step three: automatically matching special program entry conditions according to the calculation and analysis results;

step four, after entering a special program, starting to time the special program, and in the time, the LED lamp flickers at the frequency of 1HZ and executes a corresponding function; if the timing time is up or other exit conditions are met, the special program is automatically exited.

Further, the entry conditions include a power-on natural time of the refrigerator, a door opening and closing state, and a temperature control knob state.

Further, the other exit conditions include door opening and ambient temperature change meeting a threshold. When the refrigerator door is detected to be in an open state and the environmental temperature change value M is larger than N; at this time, the exit condition is satisfied; wherein N is a preset threshold value.

Further, a mapping relation table is established for controlling the special program of the refrigerator, and the mapping relation table comprises the corresponding relation between the entering conditions and the special program.

Further, the special programs include a hardware self-test program and a standby program.

Further, when the refrigerator enters a special program, the LED lamp is in a first display state; and when the refrigerator is in a normal operation program, the LED lamp is in a second display state.

The invention has the following beneficial effects:

1. the invention can detect the actual working state of the refrigerator through special procedures under the condition of conforming to the design scheme of the machine-controlled refrigerator, and verify whether the requirements proposed by customers are met; the invention distinguishes the special program and the normal operation program through the display state of the LED lamp, thereby being convenient for obtaining the operation information of the special program in time.

2. Under the condition of meeting the production and use requirements, the invention facilitates the detection and maintenance of technicians and after-sales personnel by comprehensively analyzing and processing signals such as power-on natural running time, temperature control knob operation, door opening and closing states of a room and the like on the premise of not increasing cost and meeting the current industrial design, and simultaneously ensures that a user cannot enter the refrigerator due to misoperation in the daily use process to influence the normal use of the refrigerator

Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
