The Goodman 20197308 Pressure Switch is a genuine OEM draft-safety control for the GMV951155DXA and compatible Goodman/Amana condensing furnaces. This normally-open switch senses negative pressure created by the inducer/draft blower and closes at a -0.10 inch water column setpoint, proving that combustion airflow and venting are correct before the control board allows ignition. If the switch fails to close, the furnace safely locks out.

Specifications

Part Number: 20197308
Type: Air-proving pressure switch
Setpoint: -0.10 in. W.C.
Contact Configuration: Normally Open (closes on negative pressure)
Brand Fit: Goodman / Amana condensing furnaces
Application: Draft/combustion airflow safety

OEM vs. Generic

The OEM 20197308 is factory-calibrated to the exact -0.10" WC trip point required by the GMV951155DXA's induced-draft design. Generic switches with the wrong setpoint or hysteresis cause nuisance lockouts or unsafe operation. For an airflow-safety device, OEM calibration is critical.

Installation Difficulty

Easy (2/5). Remove the pressure hose, disconnect terminals, swap the switch, and reconnect ensuring the tubing routes downward with no condensate trap. Verify the setpoint matches your original. Shut off gas and power first; professional service recommended for gas equipment.

Fits GMV951155DXA. Match the setpoint and part number before ordering.
