The utility model discloses an automatically-controlling electricity-saving and protector for an electric refrigerator. The circuit of the automatically-controlling electricity-saving and protector for the electric refrigerator mainly comprises a starting circuit, a temperature regulating circuit, a sampling circuit, a control circuit and a protecting circuit. The device can prolong the stopping and heat insulating time of the electric refrigerator, expand the temperature controlling range inside the electric refrigerator and reduce the frost layer of a freezing chamber so as to reduce the working time of a compressor. Users can regulate the temperature inside the electric refrigerator according to the specific circumstances of the food fresh preservation and the electricity-saving quantity and most effectively make use of the heat insulating property of the electric refrigerator to obtain the obvious electricity-saving effect. The automatically-controlling electricity-saving and protector for the electric refrigerator has different electricity-saving efficiencies according to different types of electric refrigerators, and the average electricity-saving efficiency can reach more than 30-50%.
