OEM Carrier Pressure Switch with Bracket for Model GB1AAV036065AGJA (HK06WC090)

This is the factory OEM replacement pressure switch with mounting bracket for the Carrier GB1AAV036065AGJA gas furnace. The pressure switch monitors negative pressure created by the inducer draft motor to confirm safe venting conditions before allowing ignition to proceed. When this switch fails — or becomes stuck open — the control board cannot verify inducer operation and the furnace locks out before ever reaching the ignition stage. Common symptoms include a blinking error code for "pressure switch open," repeated startup attempts with no heat, or the inducer motor running continuously without progressing to ignition.

  • Specs: Factory-calibrated W.C. (water column) rating matched to Carrier GB1AAV036065AGJA | Includes OEM mounting bracket | 24V control circuit | Single-port configuration — verify hose and port count on your existing switch before ordering
  • OEM vs Generic: OEM pressure switches are calibrated to the exact W.C. threshold required by your furnace's venting design. Off-spec generic switches may trip too early or too late, causing nuisance lockouts, unsafe ignition attempts, or voiding manufacturer warranties.
  • Install difficulty: 3/5 — Turn off power and gas before beginning. Tools needed: 1/4" and 5/16" nut drivers, small flathead screwdriver, needle-nose pliers. Disconnect the rubber pressure hose and two-wire connector, unmount old bracket, and reverse steps for installation. Inspect hose for cracks or blockages while switch is removed.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed and factory-specified for the Carrier GB1AAV036065AGJA gas furnace. Always cross-reference OEM part number HK06WC090 and confirm your existing switch's W.C. rating from the data plate or switch label before ordering. Our HVAC parts specialists are available to verify fitment — reach out before you buy for complete peace of mind. In stock and ships today.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier GB1AAV036065AGJA — HK06WC09?
Yes. This is the factory-specified OEM pressure switch for the Carrier GB1AAV036065AGJA — HK06WC09. 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 GB1AAV036065AGJA — HK06WC09?
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.
