OEM Carrier Pressure Switch HK06NB124 for GB1AAV036111AFJA

The Carrier HK06NB124 pressure switch is a genuine OEM replacement for the GB1AAV036111AFJA gas furnace. This safety switch verifies that the draft inducer is moving combustion air properly before the control board allows ignition, protecting against blocked vents and unsafe operation. When it fails or sticks, the furnace will not light, often paired with a pressure-switch fault code or repeated lockouts. Mounted near the inducer assembly with a small hose connection, replacement is a beginner-friendly job: cut power, pull the spade connectors and rubber tube, remove the mounting screws, and install the new switch with the same orientation. Check the hose for cracks or condensate blockage while you're in there. Calibrated to the exact pressure setpoint Carrier specifies for this furnace, so it trips reliably and won't nuisance-fault like mismatched generic switches. Restoring proper pressure sensing returns your furnace to safe, consistent heating. We ship same-day on orders placed before 3PM CST. Backed by our fit guarantee for the GB1AAV036111AFJA. Order the genuine Carrier HK06NB124 today.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier GB1AAV036111AFJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier GB1AAV036111AFJA. 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 Carrier GB1AAV036111AFJA?
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 Carrier 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 Carrier 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.
