Genuine OEM Goodman B1370150 air pressure switch, set at -0.85" WC and normally open (NO), for the Goodman GDT115-5A gas furnace. This switch proves that the inducer (draft) motor is establishing proper negative pressure before the control board allows ignition — a core combustion-safety interlock. A failed switch or blocked port typically shows as the inducer running but no ignition, often with a pressure-switch fault code.

Specifications

OEM Part Number: B1370150
Set Point: -0.85" W.C. (water column)
Contact Configuration: Normally Open (closes on draft)
Type: Single-stage negative-pressure / draft-proving switch
Brand: Goodman (fits many Amana/Janitrol units)
Fits: GDT115-5A and compatible furnaces

OEM vs. Generic

Pressure-switch set points are model-specific. A generic switch with the wrong "WC" rating or contact configuration will either fail to close (no heat) or close too early (defeating the safety). This OEM B1370150 is factory-matched to -0.85" WC / NO for correct, code-compliant operation. OEM recommended for this safety-rated part.

Installation Difficulty: Easy to Moderate

With power off, disconnect the electrical spade terminals and the rubber hose, unscrew the switch, and mount the replacement — reconnecting the hose without kinks. Straightforward, but if the new switch still won't prove, inspect the hose, drain trap, and inducer for restrictions, which is best handled by an HVAC technician.

Confirm the "WC" set point and NO/NC configuration on your original switch before ordering.

Frequently Asked Questions

Does this Pressure Switch fit my Goodman GDT115-5A — B1370150?

How do I replace the pressure switch on my Goodman GDT115-5A — 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. 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.
