Goodman B1370150 Air Pressure Switch (-0.85" WC, NO)

The B1370150 is a genuine OEM negative-air-pressure (draft-proving) switch for the Goodman ADS81155CNA furnace and compatible Goodman/Amana models. It confirms that the inducer motor is pulling proper draft through the heat exchanger before the control board allows ignition. When the inducer creates the rated vacuum, the normally-open contacts close and prove draft; if venting is blocked or the inducer is weak, the switch stays open and ignition is safely prevented.

Specifications

Set point: -0.85" water column (WC)
Contact configuration: Normally open (NO), single stage
Function: Draft / combustion air proving safety
Fit: Goodman ADS81155CNA and compatible furnaces
OEM Part Number: B1370150

OEM vs. Generic

This genuine Goodman OEM switch is calibrated to the precise -0.85" WC set point matched to your furnace's inducer and venting. Generic pressure switches with the wrong set point are a leading cause of intermittent no-heat calls and false lockouts. For reliable ignition sequencing, OEM is the safe choice.

Installation Difficulty

Easy — usually 15–20 minutes. Cut power, photograph the hose and wire routing, transfer the rubber tubing and spade terminals to the new switch, and remount. Inspect the port and tubing for moisture or blockage while you're in there.
