What Is a Control Limit?
A control limit (also known as a high-limit switch) is a safety device that monitors the temperature inside a furnace or air handler. When temperatures exceed the set point, the limit control interrupts the burner circuit to prevent overheating, equipment damage, and potential safety hazards. Replacing a faulty limit control with a genuine OEM part like the Lennox 56W27 ensures your system operates within safe parameters.
