This 120°F Hi-Limit Control is a critical safety component designed for HVAC systems, air handlers, and electric furnaces. Functioning as a high limit fan disc switch, it monitors internal temperatures to prevent equipment overheating and potential fire hazards. When the temperature reaches the 120-degree threshold, the switch automatically interrupts the electrical circuit to protect sensitive components. Its auto-reset feature ensures that once the appliance cools down to a safe operating level, the circuit closes again, restoring normal function without the need for manual intervention. This durable thermal protection switch is essential for maintaining the longevity and safety of your heating and cooling equipment.
