The Goodman B1370133 Pressure Switch is a genuine OEM safety component engineered for GSU080-4 gas furnaces. This normally-open (NO) air-proving switch monitors draft-inducer pressure and closes at a set point of -0.35" water column (WC), verifying proper venting before the ignition sequence begins. If combustion airflow is blocked or the inducer fails, the switch prevents burner operation — protecting your equipment and your home.

OEM vs. Generic

This is a factory-original Goodman part, calibrated to the exact pressure threshold your furnace's control board expects. Generic aftermarket switches often use approximate set points, which can cause nuisance lockouts or fail to prove venting reliably. Choosing OEM guarantees a correct trip pressure and clean plug-and-play fit — no re-wiring or adapter tubing required.

Installation Difficulty

Easy (1 of 5). Disconnect power, remove the two spade connectors and the rubber sensing tube, unscrew the mounting bracket, and reverse to install. Most homeowners with basic tools complete the swap in under 15 minutes. Always shut off gas and electrical power before servicing.

Backed by genuine Goodman quality. In stock and ready to ship.

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.
