The Randell HDCNT1401 Refrigerator Cold Control is a temperature-regulating component with a 30-inch capillary tube for compatible commercial refrigeration equipment. It senses temperature changes inside the refrigeration system and controls compressor cycling to maintain the selected cooling range. The unit is rated for 20A at 125/250V and 50/60Hz applications. This control is suitable for service when an existing cold control becomes inaccurate, damaged, or fails to cycle the compressor correctly. It is commonly used in commercial kitchens, restaurants, cafeterias, and foodservice refrigeration applications.
