Ensure the safety and efficiency of your heating system with this high-quality HVAC limit switch. Designed as a high-limit control, this fan disc switch serves as a critical safety sensor that monitors the internal temperature of your furnace or air handler. The L195-30F rating indicates that the switch will automatically trip and cut power to the heating source if the temperature reaches 195°F, preventing potential overheating and equipment damage. Once the system cools down by 30°F, the auto-reset feature restores functionality without manual intervention. Ideal for troubleshooting issues like furnace short cycling or a blower fan that won't turn off, this reliable component is essential for maintaining a safe residential or commercial heating environment.
