Beverage Air 502-302B Refrigerator Thermostat W/Knob 16°F-50°F 32" CAP

This thermostat is used in commercial refrigerators to control and maintain the inside temperature. It works by turning the compressor on and off based on the temperature inside the unit, helping keep food stored safely. It operates within a 16–50°F range and includes a sensing system with a capillary tube and a knob that lets users adjust the temperature easily. The sensing bulb checks the temperature inside the cabinet and sends signals to keep the cooling steady and balanced. This thermostat is commonly used in refrigerators, prep tables, and undercounter cooling units found in restaurants and commercial kitchens. If the thermostat stops working properly, it can cause uneven cooling or too much compressor cycling. Replacing it helps restore correct temperature control and keeps the refrigerator working efficiently and safely.
