Goodman B1370133 Air Pressure Switch (-0.35" WC, Normally Open)

The Goodman B1370133 is a factory-original air proving pressure switch engineered for the GMPV075-1.5 gas furnace and compatible Goodman/Amana models. This safety control confirms proper induced-draft airflow before the ignition sequence begins, protecting your system from unsafe combustion conditions. When the inducer establishes negative pressure, the switch closes and allows the furnace control board to proceed; if venting is blocked or the inducer fails, it locks out ignition.

Specifications

Trip Point: -0.35" water column (WC)
Contact Type: Normally Open (NO)
Function: Induced-draft / vent airflow proving
Fits: Goodman GMPV075-1.5 and select GMP/GMPV series furnaces
Equipment: Gas furnace

OEM vs. Generic

This is a genuine OEM Goodman part built to the exact -0.35" WC calibration your furnace's control logic expects. Generic universal switches often carry loose pressure tolerances that cause nuisance lockouts or fail to protect against blocked-vent conditions. For a critical combustion-safety component, OEM calibration accuracy is strongly recommended.

Installation Difficulty

Easy (1/5) — Two spade terminals and a single rubber vent hose. Cut power at the breaker, photograph the wiring, transfer the hose and leads to the new switch, and remount. Typically a 10–15 minute repair for a handy homeowner or any HVAC technician.

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?
