The Goodman B1370150 Pressure Switch is a genuine OEM safety control rated at -0.85" WC, normally open (NO), built for GMPN100-4 gas furnaces. This switch confirms that the inducer/draft motor is pulling adequate vent airflow before allowing the ignition sequence to proceed — a critical safety interlock that prevents the furnace from firing without proper venting. A failed switch is a leading cause of furnaces that lock out, short cycle, or won't ignite.

Specifications

Part Number: B1370150
Set Point: -0.85" WC (water column)
Configuration: Normally Open (NO), closes on draft
Brand: Goodman (OEM)
Compatible Model: GMPN100-4 Furnace

OEM vs. Generic

The trip point on this switch is a life-safety setting — generic switches with loose or mismatched calibration can either nuisance-trip or, worse, allow firing under poor-draft conditions. The genuine Goodman B1370150 is factory-calibrated to the exact -0.85" WC set point and NO configuration your furnace's control logic expects.

Installation Difficulty

Easy to Moderate (2/5). Power down the furnace, disconnect the two spade terminals and the rubber pressure hose, unscrew the switch, and mount the replacement — reconnecting the hose without kinks. Verify ignition and draft proving on startup. Professional installation recommended for combustion safety controls.

Keep your GMPN100-4 igniting safely and reliably with a genuine OEM pressure switch. In stock and ships fast.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman GMPN100-4 — B1370150?

How do I replace the pressure switch on my Goodman GMPN100-4 — B1370150?

Difficulty: Medium (20–30 min)
Step 1: Turn off power. Step 2: Locate pressure switch near draft inducer. Step 3: Note tubing orientation. Step 4: Disconnect tubing and wires. Step 5: Remove screw, install new switch. Step 6: Reconnect tubing and wires, restore power.

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.

The same physical part is often used across brand labels with different model numbers.

Should I use OEM or aftermarket for my Goodman pressure switch?
