OEM Carrier Pressure Switch HK06NB124 for Model GB3AAV024070AGJA

This genuine OEM Carrier pressure switch (HK06NB124) safeguards your GB3AAV024070AGJA gas furnace by confirming proper draft inducer airflow before the burners ignite. If your furnace locks out, fails to light, or signals a pressure-switch fault code, a stuck or out-of-spec switch is a frequent culprit. This factory-original part is calibrated to the exact inches-of-water-column setpoint your model requires, ensuring safe, code-compliant operation that universal switches cannot reliably match. Installation is easy—a confident DIYer can complete it in 15 to 20 minutes using a nut driver and being careful to reconnect the rubber hose securely; shut off power and gas before starting. Protect your home and restore dependable heat with a Carrier-engineered safety component built to OEM tolerances. We keep this part in stock and ship same-day on orders placed before 3PM CST, minimizing furnace downtime during cold weather. Choose genuine fitment for confident, lasting repairs.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier Model GB3AAV024070AGJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier Model GB3AAV024070AGJA. 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 GB3AAV024070AGJA?
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.
