International Comfort Products 1185459 Furnace High Limit Switch - L195-20F

The International Comfort Products 1185459 is an OEM furnace high limit switch rated L195-20F, designed as a critical safety component in residential and light commercial gas furnace systems. This limit switch monitors heat exchanger temperature and automatically interrupts the burner circuit when a dangerous overheat condition is detected.

How It Works:

The L195-20F designation describes the switch's operating range: the switch opens (trips) at 195°F to shut down the burner, preventing heat exchanger damage and potential fire hazard. It is a manual or auto-reset type safety device wired in series with the furnace burner control circuit. If the furnace overheats repeatedly, the switch may require replacement rather than simply resetting.
