Goodman B1370107 Air Pressure Switch (-1.4" WC, NO)

The Goodman B1370107 is a genuine OEM negative-pressure (draft-proving) switch built for the GUN050-2B gas furnace. This normally-open switch monitors the vacuum created by the inducer/draft motor and closes at a -1.4 inch water-column setpoint to confirm safe venting before the ignition sequence begins. If the flue is blocked, the inducer is weak, or a hose is cracked, the switch stays open and locks out the burner — protecting your home from carbon-monoxide spillage.

Specifications

Setpoint: -1.4 in. water column (WC)
Configuration: Single-pole, Normally Open (NO)
Function: Combustion air / venting proving switch
Fits: Goodman GUN050-2B furnace
OEM Part Number: B1370107
Connection: Standard spade terminals with pressure-tap port

OEM vs. Generic

The OEM B1370107 is calibrated to the exact -1.4" WC trip point specified for this furnace, which is critical for a safety device — an incorrectly rated switch can nuisance-trip or, worse, allow ignition under unsafe draft. Our generic-equivalent is matched to the same setpoint and terminal layout at a lower cost; for a pressure switch we generally recommend the OEM given its safety role.

Installation Difficulty

Rating: Easy (2/5). Disconnect power, unplug the two wire leads and the rubber pressure hose, remove the mounting screws, and reverse for the new switch. Verify the hose is clear of condensate and seated firmly. Takes about 10-15 minutes with a nut driver.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman GUN050-2B — B1370107?

Yes. This is the factory-specified OEM pressure switch for the Goodman GUN050-2B — B1370107. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the pressure switch on my Goodman GUN050-2B — B1370107?

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.

Is this pressure switch compatible with Bryant or Payne too?

Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

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

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
