The Goodman B1370176 Pressure Switch is a genuine OEM normally-open (NO) draft-proving switch rated at -0.47 in. WC for the AMH80704BXAA gas furnace and compatible Goodman/Amana models. It verifies that the inducer/draft blower is pulling proper negative pressure before allowing ignition. If the flue is blocked, the inducer is weak, or a hose is cracked, the switch stays open and locks out the burners — protecting against incomplete combustion. A stuck or out-of-spec switch is a leading cause of no-heat and ignition lockout faults.

Specifications

Set point: -0.47 in. water column
Contact type: Normally open (NO)
Function: Draft / air-flow proving safety
OEM part number: B1370176
Fits: Goodman/Amana AMH80704BXAA and select furnace models

OEM vs. Generic

The OEM B1370176 is calibrated to Goodman's exact -0.47" WC trip pressure and port configuration. A generic switch with a different set point or hose barb can cause false lockouts or unsafe firing. Because it gates combustion, OEM is strongly recommended.

Installation Difficulty

Easy — remove the mounting screws, transfer the pressure hose to the same port, and reconnect the terminals. Verify the hose is clear and correctly routed. A capable DIYer can do it quickly. Disconnect gas and power first.

My furnace shows a pressure switch error. What do I replace?

Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.

Should I use OEM or aftermarket for my Goodman pressure switch?
