Description
The International Comfort Products 1171904 is an OEM replacement L145-55F limit switch engineered to protect furnaces and heating systems from dangerous overheating conditions. Designed as a direct factory replacement for compatible International Comfort Products equipment, this limit switch delivers dependable, precise thermal protection to keep your system running safely and efficiently.
How It Works
The limit switch continuously monitors supply air or heat exchanger temperatures. When temperatures rise to the upper threshold, the switch opens the circuit to shut down the burner, preventing heat exchanger damage and potential safety hazards. Once temperatures return to a safe level, the switch resets to restore normal furnace operation.
