Description
The International Comfort Products 1185983 is an OEM replacement limit switch engineered to protect furnaces and air handlers from dangerous overheating conditions. Designed as a direct-fit replacement for compatible ICP, Heil, Tempstar, and related equipment, this limit switch delivers reliable, repeatable performance to keep heating systems operating safely and efficiently.
How It Works
The limit switch continuously monitors supply-air or heat exchanger temperatures. When temperatures rise to the open setpoint, the switch interrupts the burner circuit to prevent overheating. Once the unit cools to the reset temperature, the switch automatically restores normal operation — protecting both the equipment and the occupants.
