Control method and device for refrigerator, and refrigerator

Abstract

A control method and device for a refrigerator, and the refrigerator. The refrigerator comprises at least two compartments. The control method comprises: acquiring a compartment currently requesting cooling; after detecting and confirming a first set time, the compartment currently requesting cooling not being cooled, determining a currently cooled compartment, and interchanging currently set valve body rotation angles corresponding to the compartment currently requesting cooling and the currently cooled compartment requesting cooling. The present disclosure may solve the problem in which a refrigerator cannot be cooled normally due to a connection error between the capillary tube and a solenoid valve during the production of a multi-system refrigerator, and reduces the refrigerator repair rate, improves the refrigerator production efficiency, and reduces fabrication costs.
