Amana-Goodman 20197314 Pressure Switch

The Amana-Goodman 20197314 Pressure Switch is a critical safety component designed for high-efficiency furnace applications, specifically calibrated to monitor draft inducer motor performance. This single-pole single-throw (SPST) vacuum switch is factory-set to trip at -.16" WC, ensuring that the combustion process only proceeds when proper venting pressures are maintained. Engineered with a standard 1/4" barb connection, it provides a secure fit for pneumatic tubing, preventing vacuum leaks that lead to intermittent furnace pressure switch lockout codes. As a direct OEM replacement part, this switch ensures the control board receives precise signal feedback regarding flue gas velocity. This unit is the designated HAPS27 replacement, offering exact electrical specifications and mounting footprints for Amana and Goodman footprints. For contractors troubleshooting a furnace not igniting, verifying the pressure switch continuity on this -.16" WC component is an essential diagnostic step to ensure system reliability and secondary heat exchanger safety.

Key Benefits

• Exact Calibration: Pre-set at -.16" WC to meet precise manufacturer specifications for combustion safety.
• Direct Interchangeability: Serves as the official 20197314 replacement for the legacy HAPS27 model, ensuring seamless retrofitting.
• Standardized Connectivity: Features a 1/4" barb connection and standard spade terminals for rapid field installation.
• OEM Reliability: Genuine Goodman furnace parts construction ensures proper diaphragm response under high-heat conditions.

Common Questions

Will this switch fix a 3-flash error code on a Goodman furnace?
A 3-flash code typically indicates a pressure switch fault. If your manometer confirms the inducer is pulling sufficient vacuum but the 20197314 switch fails to close, a replacement is necessary.

Can I use this to replace a switch with a different WC rating?
No. Pressure switches are safety devices calibrated to specific inches of water column. Using a switch other than the -.16" WC rated 20197314 can result in hazardous combustion conditions or frequent nuisance trips.

Does this switch handle ignition or blower functions?
This is a draft inducer safety switch. It specifically monitors flue venting; it does not directly control the indoor blower motor or the igniter sequence.
