The Klixon Fan Disc High Limit Control Switch is an essential safety component designed for HVAC systems and furnaces. This thermal limit switch monitors the internal temperature of your heating equipment to prevent overheating and potential system damage. Utilizing a precision bi-metal disc mechanism, it automatically interrupts the electrical circuit if the temperature rises above a safe threshold, ensuring the unit shuts down safely while allowing the fan to circulate air and cool the heat exchanger. Ideal for professional furnace repair and maintenance, this reliable limit sensor helps maintain optimal performance and protects your heating system from thermal overload. If your heating system is short-cycling or failing to activate the burner, replacing a worn-out high limit control can restore safe and efficient operation.
