The Goodman B1370126 Pressure Switch is a genuine OEM safety control for the GUP050-2A gas furnace, rated to close at -0.40 inches of water column (WC) and wired normally open (NO). This switch confirms that the induced-draft blower has established proper venting before the ignition sequence is allowed to proceed. If adequate draft is not sensed, the switch keeps the burners locked out — protecting against dangerous flue-gas conditions.

Specifications

OEM Part Number: B1370126
Set Point: -0.40 in. WC
Contact Configuration: Normally Open (NO)
Function: Draft / vent safety proving switch
Application: Goodman GUP050-2A gas furnace
Type: Genuine Goodman OEM replacement

OEM vs. Generic

Because this is a safety device, matching the exact -0.40" WC set point and NO configuration is critical. The genuine Goodman OEM switch is calibrated to factory spec. A generic switch with a slightly different trip point can cause nuisance lockouts or, worse, fail to protect properly. For any combustion-safety component we strongly recommend OEM; a verified-compatible generic is offered only where set point and configuration match exactly.

Installation Difficulty

Easy (2 of 5). Typically 15–20 minutes. Disconnect power, note the hose and wire positions, then transfer the draft hose and terminals to the new switch. Confirm the hose is free of blockage and the switch closes on an ignition cycle. Because it is a safety control, verify correct operation — or have a licensed HVAC technician perform the replacement.

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?
