The Goodman 20197308 Pressure Switch is a genuine OEM -.10 in. WC, normally open draft-proving switch for the GMH950704CXAE and compatible Goodman/Amana furnaces. It confirms that the induced-draft blower is producing adequate negative pressure before the control board allows ignition. If venting is blocked, the inducer is weak, or the condensate trap is clogged, the switch stays open and safely prevents the burners from firing.

Specifications

Set point: -0.10 in. WC (water column)
Contact configuration: Normally Open (closes on draft)
Single-stage/low-fire draft proving
Direct OEM fit for GMH950704CXAE
OEM Part Number: 20197308

OEM vs. Generic

OEM pressure switches are factory-calibrated to the exact -.10" WC set point and contact type your furnace board expects. A generic switch with the wrong set point or configuration can allow unsafe ignition or cause persistent lockouts. For a combustion-safety control, OEM is the correct choice.

Installation

Difficulty: Easy–Moderate (2/5). Cut power, disconnect the electrical terminals and the rubber pressure hose, unscrew the switch, and mount the replacement in the same position. A licensed HVAC technician should verify the switch closes on a good draft and check for hose leaks.
