This professional-grade disc limit switch is a vital safety component for residential and commercial heating systems. Engineered as a high-limit control, this switch monitors internal temperatures within furnaces and air handlers to prevent hazardous overheating. The L195-40F specification ensures that the switch triggers at a 195°F threshold, interrupting the heating cycle to protect the heat exchanger and surrounding components. Featuring a 40°F differential, this auto-reset switch restores the circuit once the system has cooled to a safe operating temperature, eliminating the need for manual intervention. This reliable fan disc control is an essential replacement part for HVAC maintenance, ensuring peak appliance safety and system longevity.
