OEM Goodman -.10" WC NO Pressure Switch AMVM960603BXAA — 20197308

OEM Goodman 20197308 Pressure Switch (-.10" WC, Normally Open)

The Goodman 20197308 is a genuine OEM air-proving pressure switch calibrated to a -0.10 inch water-column setpoint with normally open (NO) contacts, designed for the AMVM960603BXAA modulating gas furnace. This switch verifies that the inducer motor has established proper draft before the ignition sequence begins. If adequate negative pressure is sensed, the contacts close to prove airflow; if not, the control board halts ignition to prevent unsafe combustion. An out-of-spec or failed switch is a common cause of no-heat lockouts and short cycling.

OEM vs. Generic

Pressure switches are setpoint-critical — even a small deviation in the -.10" WC trip point causes false lockouts or, worse, allows ignition without proven draft. Generic switches frequently ship with the wrong setpoint or hose-port orientation. The OEM 20197308 is factory-calibrated to the exact spec Goodman's control board expects, so the furnace proves draft correctly and safely.

Install Difficulty

Moderate (2 of 5). Involves transferring the sensing hose and spade connectors to the new switch and mounting it in the original location — about 15 minutes. Always disconnect power before service and confirm the setpoint and NO/NC configuration match the switch you removed. If lockouts persist after replacement, have a licensed technician check the inducer and drain system.
