Amana-Goodman B1370176 Pressure Switch

The Amana-Goodman B1370176 Pressure Switch is a critical safety component designed for specific high-efficiency furnaces. Calibrated to a -0.47" WC set point, this SPST (Single Pole Single Throw) vacuum switch monitors the pressure differential within the inducer housing to ensure the combustion blower is extracting flue gases safely before allowing the ignition sequence to proceed. Featuring a standard 1/4" barbed connection and 1/4" male spade terminals, this OEM replacement pressure switch ensures seamless integration with existing wiring harnesses. It is engineered to withstand the thermal cycling common in mid-to-high-efficiency heating systems, preventing nuisance trips while maintaining strict adherence to combustion safety protocols. When troubleshooting Goodman furnace pressure switch stuck open codes, this factory-spec component provides the precise pneumatic-to-electrical signal required by the integrated furnace control board. Professional installation is recommended to ensure correct furnace pressure switch calibration and venting integrity.

• Precise Actuation: Factory-set at -0.47" WC for accurate sensing of inducer motor performance.
• Drop-in Compatibility: Features a 1/4 inch barbed connection for quick installation of pneumatic tubing.
• OEM Reliability: Authentic Amana-Goodman replacement part designed for specific heat exchanger configurations.
• Durable Construction: Built with robust materials to resist diaphragm fatigue in high-temperature environments.

How do I know if my B1370176 pressure switch is failing?
If your furnace displays a 3-flash code or stays in the inducer pre-purge cycle without igniting, the B1370176 pressure switch may be failing to close due to a ruptured diaphragm or moisture in the sensing line.

Can I use a switch with a different " WC rating?
No. Using a switch with a different set point than the -0.47" WC specification can result in dangerous combustion conditions or frequent system lockouts.

Does this switch include the sensing tubing?
This is the switch assembly only. We recommend inspecting your existing 1/4 inch tubing for cracks or debris during replacement.
