This 5/8-inch disc limit switch is a vital safety component designed for residential furnaces and HVAC systems. As a high-limit control, it monitors the heat exchanger temperature to prevent overheating. When the internal temperature reaches the fixed 125°F setpoint, the switch opens to interrupt the circuit, protecting the appliance from potential damage. Its automatic reset feature ensures the circuit closes again once the temperature drops by the 30°F differential. Replacing a malfunctioning limit switch is essential for restoring proper heating cycles and ensuring the blower fan operates correctly. This durable temperature sensor provides reliable performance for forced-air heating applications.
