OEM Carrier Pressure Switch HK06NB124 for Model GB1AAV036111ABJA

This OEM Carrier pressure switch (HK06NB124) is a critical safety control for your GB1AAV036111ABJA gas furnace. It monitors draft and vent flow, confirming the inducer motor has established proper combustion airflow before ignition begins. If the vent is blocked or the inducer is weak, the switch opens and stops the furnace from firing, protecting against dangerous flue gas spillage. Built to exact factory specifications, this pressure switch matches the original tubing connection, trip point, and electrical rating for the GB1AAV036111ABJA, ensuring reliable and code-compliant operation. Installation is a moderate DIY repair: shut off power and gas, photograph the wiring and hose routing, transfer the tube and electrical terminals, then mount the new switch. Most repairs take under 30 minutes with basic hand tools. A failing pressure switch commonly causes lockouts, short cycling, or a furnace that ignites then immediately shuts down. Replacing it with a genuine OEM part restores dependable heat and eliminates guesswork. In stock and ships same-day when ordered before 3PM CST.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier Model GB1AAV036111ABJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier Model GB1AAV036111ABJA. 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 Model GB1AAV036111ABJA?
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.
