Product Details

The Reznor 174809 is a genuine OEM SPDT (Single Pole Double Throw) pressure switch designed for use in Reznor furnaces and unit heaters. This safety control monitors air pressure to ensure proper system operation and safe venting of combustion gases.

Key Features:

  • Pressure rating: 1.10 inches water column (WC)
  • SPDT switch configuration with dual-circuit design for versatile control applications
  • Compatible with air, natural gas, and LP gas applications
  • Ensures inducer motor operates at proper speed and creates adequate vacuum for safe flue operation
  • Direct replacement for part numbers GFS3602-2997 and 03651/1144/A
  • Genuine Reznor OEM part for reliable performance and longevity

This pressure switch serves as a critical safety component in heating systems by monitoring differential pressure and signaling the control board when proper airflow conditions are met. The SPDT configuration allows the switch to control two separate circuits, making it ideal for interlocking controls and safety shutoff applications in gas-fired heating equipment.
