Description
The Amana-Goodman 20197313 is a factory-authorized OEM pressure switch engineered to protect furnaces and air handlers from unsafe operating conditions. With a calibrated setpoint of -0.37″ water column (w.c.), this switch monitors negative pressure in the venting or combustion air circuit and interrupts the control circuit when pressure falls outside safe limits — helping prevent incomplete combustion, flue gas spillage, and heat exchanger damage.
Key Features
- OEM Amana-Goodman replacement pressure switch — direct factory fit
- Setpoint: -0.37″ w.c. (negative pressure)
- SPST (Single-Pole, Single-Throw) switching action for simple open/close circuit control
- 1/4″ barb port connection for secure, leak-free tubing attachment
- Designed to integrate with Amana-Goodman furnace and air handler control boards
- Helps safeguard heat exchanger integrity and ensures proper draft inducer operation
Application
This pressure switch is a direct OEM replacement for select Amana-Goodman furnaces and heating systems. It is typically located in the combustion air or inducer assembly circuit, where it verifies that the draft inducer is generating adequate negative pressure before allowing the ignition sequence to proceed. Using the correct OEM part ensures accurate setpoint calibration and reliable system protection.
Installation Notes
- Always verify the replacement part number against the original switch on your unit
- Disconnect power before servicing
- Connect 1/4″ ID tubing securely to the barb port to prevent false trips or pressure leaks
- Consult the equipment service manual for wiring diagram and mounting location
