This Hi Limit Switch/Thermostat is a critical safety component designed for HVAC systems and furnaces. Featuring a 3-inch probe insert, this high limit control monitors internal temperatures to prevent overheating. If the system's temperature reaches the safety threshold of 130°F, the switch automatically interrupts the circuit to protect your heating equipment from potential damage or fire hazards. As an auto-reset thermal switch, it is designed to restore connectivity once the unit cools down by 30°F, ensuring the continuous and safe operation of your air handler or furnace. This reliable temperature sensor is an essential replacement part for maintaining the safety standards and efficiency of residential heating units.
