OEM Carrier Pressure Switch HK06NB124 for Model GB1AAV036045ABJA

This OEM Carrier pressure switch (HK06NB124) safeguards your Carrier GB1AAV036045ABJA gas furnace by confirming proper inducer draft before ignition is permitted. It senses the negative pressure created by the inducer motor and closes its contacts only when venting is adequate, blocking ignition if the flue is obstructed or the inducer is weak. A faulty switch causes lockouts, failure to ignite, and pressure-switch fault codes even when the rest of the furnace is healthy. Manufactured to exact Carrier specifications, this switch trips at the precise pressure your furnace demands for safe combustion. Installation is easy at roughly 15-20 minutes: disconnect power, pull the tubing and wire terminals, mount the new switch, and reconnect. Check the hose for trapped condensate before finishing. Genuine OEM parts guarantee correct calibration and protect your warranty. In stock today — orders placed before 3PM CST ship the same day. Restore safe, reliable furnace operation with the exact pressure switch Carrier built for this model.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier Model GB1AAV036045ABJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier Model GB1AAV036045ABJA. 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 GB1AAV036045ABJA?
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.
