International Comfort Products 1186809 Limit Switch F Boiler Safety Controls & Aquastats - 185 F-145

The International Comfort Products 1186809 is a temperature-activated limit switch designed for HVAC furnace applications. This safety control automatically opens at 185°F and closes at 145°F to prevent overheating and protect your heating system from damage.

Key Features:

• Opening temperature: 185°F (85°C)
• Closing temperature: 145°F (63°C)
• Automatic reset functionality for continuous protection
• Direct replacement for ICP, Heil, Tempstar, and Comfortmaker furnaces
• Essential safety component that cuts power to the burner when excessive heat is detected

This limit switch is a critical safety device that monitors plenum temperature and prevents furnace overheating caused by restricted airflow, dirty filters, or blower motor failure. When the limit switch opens due to high temperature, it interrupts the heating cycle until the temperature drops back to the safe reset point.
