OEM Carrier Pressure Switch HK06NB124 for Model GB1AAV036045AGJA

The OEM Carrier pressure switch (HK06NB124) is a critical safety device that verifies proper draft and venting before the furnace allows ignition. It senses negative pressure created by the inducer motor and closes its contacts to confirm exhaust gases are flowing safely; a stuck-open switch, blocked hose, or weak inducer triggers a lockout and prevents the burners from firing. This switch is a direct-fit replacement for the Carrier GB1AAV036045AGJA furnace, calibrated to the exact pressure setpoint and fitted with the matching port and terminals for a precise swap. Installation is easy for most homeowners: cut power, disconnect the rubber tubing and spade wires, remove one mounting screw, and reverse to install. Always clear the hose of condensate before assuming the switch is bad. The genuine OEM switch guarantees the correct trip point, unlike generic units that can allow unsafe operation or cause false lockouts. In stock and ships same-day on orders before 3PM CST. Restore safe, reliable ignition with the exact pressure switch Carrier specified.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier Model GB1AAV036045AGJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier Model GB1AAV036045AGJA. 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 GB1AAV036045AGJA?
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.
