OEM Carrier LP Gas Pressure Switch HK02LB008 / HK06WC091 for Model PG8MAA024070AFJA

This OEM Carrier LP gas pressure switch is the factory-specified replacement for the Carrier PG8MAA024070AFJA packaged gas unit. The pressure switch is a critical safety device that monitors the gas supply pressure and proves that the inducer motor is operating correctly before allowing ignition to proceed. When this switch fails or sticks, the furnace will enter a lockout condition — typically refusing to fire, cycling off before the burners light, or flashing a fault code indicating a pressure switch error. Both OEM part numbers HK02LB008 (Gas Pressure Switch) and HK06WC091 (Pressure Switch) are covered by this listing and are direct application matches for this model.

  • Specs: LP / Propane gas application | Cut-out pressure: 6.5" W.C. | SPST configuration | Fits Carrier, Bryant, and Payne packaged and furnace units | Factory-matched pressure setpoint
  • OEM vs Generic: OEM pressure switches are factory-calibrated to exact W.C. specifications. Generic aftermarket switches frequently deviate from setpoint tolerances, causing nuisance lockouts or — more dangerously — allowing ignition under unsafe draft conditions.
  • Install difficulty: 2/5 — Shut off gas and power at the disconnect before beginning. Tools needed: 1/4" nut driver, needle-nose pliers, and a short length of replacement vacuum tubing if the original is cracked. Always label hose ports before disconnecting. Verify LP vs. natural gas application on your unit's data plate before ordering.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8MAA024070AFJA packaged gas unit. Also fits a wide range of Carrier, Bryant, and Payne gas furnaces and packaged units sharing the HK02LB008 / HK06WC091 pressure switch specification. Always confirm LP vs. natural gas application and W.C. rating on your unit's data plate before ordering. Questions about fitment?

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8MAA024070AFJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8MAA024070AFJA. 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 PG8MAA024070AFJA?
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.
How fast does National HVAC Parts ship?
