Control of components: (1) Compressor If refrigeration is required, turn on the compressor; if not, turn off the compressor; The downtime of the compressor must be more than 8 minutes before it can be started again; (2) Light When the refrigerating door is opened, the refrigerating light will be on. When the refrigerating door is closed, the refrigerating light will go out;...

Failure running program: When the temperature sensor for the freezer chamber fails, the refrigeration will proceed in the following chronological order: 25 minutes of refrigeration, and then 25 minutes of no refrigeration. When the ambient temperature sensor fails, the temperature will be controlled at 25℃. In case of communication failure, it will run in the gear before the failure.
