Amana-Goodman 10727921 Furnace Air Pressure Switch WC - 0.75

The Amana-Goodman 10727921 is an OEM furnace air pressure switch designed for use with Goodman and Amana gas furnaces. This safety switch monitors air pressure within the furnace system to ensure proper inducer motor operation before allowing the burner to ignite.

Key Features:

• Pressure setpoint rated at -0.75 inches water column (WC)
• Single hose port configuration for pressure sensing
• Two-wire terminal connection for electrical hookup
• OEM replacement part ensuring proper fit and function
• Safety device that prevents furnace ignition if proper vacuum is not detected

This pressure switch works as a critical safety component in conjunction with other furnace controls to verify that the inducer motor is running at the correct RPM and creating adequate negative pressure for safe venting of combustion gases. If the switch does not sense proper vacuum, it will not allow the furnace to initiate the ignition sequence, protecting against potentially dangerous flue gas spillage.
