Description
The International Comfort Products 1184896 is an OEM replacement L200-20F high-limit switch designed to protect furnaces and heating systems from dangerous overheating conditions. When supply air temperatures exceed the rated setpoint, this limit switch interrupts the burner circuit, preventing heat exchanger damage and ensuring safe system operation.
How It Works
The L200-20F designation identifies the operating parameters of this limit switch. It opens (trips) at 200°F to shut down the burner when excessive temperatures are detected in the heat exchanger or supply air plenum. Once temperatures drop and safe conditions are restored, the switch automatically resets, allowing normal furnace operation to resume. This automatic reset design minimizes service calls while maintaining reliable overheat protection.
