This 3/4-inch High Limit Disc Switch is an essential safety component designed for HVAC systems and forced-air furnaces. Functioning as a thermal protection device, this switch monitors internal temperatures to prevent the heat exchanger from overheating. When temperatures reach the 165-degree Fahrenheit threshold, the switch automatically opens to interrupt the heating cycle, protecting the appliance from damage. Once the system cools by 40 degrees, the automatic reset feature restores the connection, allowing for seamless continued operation. This durable fan disc switch is a vital replacement part for maintaining the safety, efficiency, and longevity of residential and commercial heating units.
