Description

The White-Rodgers 3L01-191 is a reliable snap disc limit control designed for fixed temperature limiting in heating, ventilation, and air conditioning (HVAC) systems, appliances, and industrial equipment. This bimetallic snap disc thermostat automatically opens at 190°F to prevent overheating and closes at 150°F to resume operation, providing a 40°F differential for precise thermal protection. It features a compact, durable design with quick response times, making it ideal for applications such as furnaces, boilers, water heaters, and electric heaters where overtemperature safety is critical. Advantages include high accuracy, long service life, and easy installation without calibration needs, outperforming adjustable thermostats in fixed-setpoint scenarios by reducing maintenance. Drawbacks may include lack of adjustability for varying temperature requirements and potential sensitivity to vibration in extreme environments. Based on attached images, the unit appears new in original packaging, with clear labeling and no visible wear. For detailed specs, refer to manufacturer datasheets from Emerson (e.g., search 'White-Rodgers 3L01-191 datasheet PDF' on emerson.com).
