The Goodman 20197308 Pressure Switch is a genuine OEM air-proving safety control calibrated at -.10" WC (normally open) for the Amana/Goodman AMVC950453BXBA variable-speed condensing furnace. This switch confirms that the induced-draft blower is producing adequate negative pressure before the ignition sequence begins, ensuring safe combustion and proper venting.

If the switch fails to close, the furnace will lock out and refuse to light — a common symptom of a bad switch, a clogged drain trap, or a blocked vent. Replacing a drifted or stuck switch with the exact OEM 20197308 restores reliable, code-compliant operation.

Specifications

OEM Part Number: 20197308
Set Point: -.10" WC (water column)
Configuration: Normally Open (NO), single stage

OEM vs. Generic

The OEM 20197308 is factory-matched to the exact -.10" set point and hose-port orientation your control board expects. Generic switches with the wrong calibration can cause false lockouts or, worse, allow unsafe operation. For a critical combustion-safety component, genuine OEM is strongly recommended; a tested generic equivalent is available where an exact-spec substitute is verified.

Installation Difficulty

Easy (2/5). Roughly 15–20 minutes. Cut power, photograph the wiring, transfer the two spade terminals and the pressure hose to the new switch, and mount it. Verify furnace ignition and confirm the switch closes on inducer startup.
