Amana-Goodman 20197312 Pressure Switch

The Amana-Goodman 20197312 Pressure Switch is a critical safety component designed for precise HVAC pressure monitoring in residential and light commercial equipment. This genuine OEM Goodman part features a factory-calibrated 0.37" WC setpoint, identified by its light blue casing. As a furnace pressure switch replacement, it plays a vital role in the combustion process by ensuring the inducer motor is moving sufficient air before allowing the ignition sequence to proceed. Whether you are dealing with a Goodman 20197312 failure or performing preventive maintenance on an Amana air conditioner or heat pump, using factory-authorized HVAC parts is essential for maintaining UL certifications and internal safety protocols. This single-pole, single-throw (SPST) switch is engineered to withstand the rigorous thermal cycling common in modern high-efficiency systems, providing a reliable OEM HVAC replacement solution that avoids the calibration drift often seen in universal aftermarket alternatives.

Key Benefits for Contractors

• Exact Compatibility: Designed specifically for Goodman and Amana HVAC systems, eliminating the need for field modifications or bracket adjustments.
• Reliable Construction: High-grade diaphragm and contact materials prevent premature pitting or sticking in high-moisture environments.
• Simplified Identification: Light blue color-coding allows for rapid visual verification during HVAC diagnostics.
• Ready for Install: Shipped brand new in original Goodman factory packaging to ensure the component remains contaminant-free until installation.

Frequently Asked Questions

What causes a 20197312 pressure switch to trip?
Beyond a mechanical failure of the switch itself, common causes include blocked vent pipes, a failing inducer motor, or a clogged condensate drain in high-efficiency condensing furnaces.

Can I use a universal switch instead of this OEM part?
While universal switches exist, they often require manual calibration. Using this genuine OEM part ensures the 0.37" WC setpoint is accurate to factory specs, maintaining system safety and performance.

How do I verify if this switch is the issue?
Check for continuity across the terminals when the inducer is running. If the inducer generates sufficient vacuum but the switch fails to close, a replacement of the 20197312 is likely necessary.
