A refrigerator includes a cabinet and a door connected to the cabinet. The door includes a door sheet body, a side cover connected to an end portion of the door sheet body and a controller fixed to the side cover. The side cover is provided with an installation hole which faces away from an opening at a side of the door sheet body, and a cover member configured to seal the opening. The controller is located in the installation hole. The controller is installed in the side cover, so as not to be damaged by being immersed in a foaming liquid, thereby enabling a simpler assembly process.
