The DISC LIMIT SWITCH AUTO RESET L150-40F is a critical safety component designed for HVAC systems, including furnaces and air handlers. This high-limit control switch monitors the internal temperature of the appliance to prevent overheating and potential damage. When the temperature reaches the 150°F threshold, the switch automatically opens the circuit to cut power to the heating source. As the unit cools down by 40°F, the auto-reset feature restores the electrical connection, allowing for safe and continuous operation without manual intervention. This durable thermal disc is an essential replacement part for maintaining the safety and reliability of residential heating equipment.
