Goodman B1370150 Draft Pressure Switch — -0.85" WC (N.O.)

The B1370150 is a genuine OEM negative-pressure (draft) switch for the Goodman GMNT100-4 gas furnace. It verifies that the inducer/draft blower is producing adequate airflow before the control board allows the igniter and gas valve to fire. When the inducer proves draft, the normally open contacts close to signal the board. A failed switch, a cracked hose, or a blocked vent commonly shows up as a furnace that runs the inducer but never lights.

Specifications

Set point: -0.85" water column (WC)
Contact configuration: Normally Open (N.O.)
Function: Draft / vent air-proving switch
Compatible model: Goodman GMNT100-4
OEM part number: B1370150
Brand: Goodman (genuine OEM)

OEM vs. Generic

The OEM B1370150 is factory-calibrated to the exact -0.85" WC set point required by the GMNT100-4 combustion design — the correct set point is essential for safe, reliable ignition. Generic pressure switches must match set point, contact configuration, and port/hose fitting; an incorrect set point can cause nuisance lockouts or unsafe operation.

Installation Difficulty: Easy

Turn off power, disconnect the two spade terminals and the sensing hose, remove the mounting screws, and install the new switch. Inspect the sensing hose and inducer port for blockage or condensate while you're in there.
