OEM Carrier Gas Pressure Switch HK02LB008 / HK06WC091 for Model PG8MEA048070ACJA

This OEM gas pressure switch is the factory-specified replacement for the Carrier PG8MEA048070ACJA packaged gas unit. The pressure switch monitors the negative pressure (vacuum) created by the draft inducer motor to confirm safe combustion airflow before allowing the gas valve to open. When it fails or sticks open, the furnace will lock out before ignition — leaving you with a blinking error code and no heat. Common symptoms include the inducer running but the furnace never advancing past the pre-purge stage, or a fault code indicating a failed pressure switch.

  • OEM Part Numbers: HK02LB008 (Gas Pressure Switch) | HK06WC091 (Pressure Switch High Fire) — both are factory-authorized Carrier/Honeywell parts covering this model's pressure switch circuit
  • Specs: SPST configuration | Rated for LP and natural gas applications | Cut-out pressure set at 6.5" W.C. | Mounts horizontally or vertically | Compatible with Carrier, Bryant, and Payne platforms
  • OEM vs Generic: OEM pressure switches are factory-calibrated to the exact W.C. setpoint for the PG8MEA048070ACJA heat exchanger. Generic aftermarket units often carry wider pressure tolerances that can cause nuisance lockouts or — worse — allow the furnace to fire without confirmed draft, creating a carbon monoxide risk.
  • Install difficulty: 2/5 — Power down and lock out the unit before starting. Tools needed: 1/4" nut driver, flat-head screwdriver, manometer (recommended to verify W.C. after swap). Photograph hose routing before disconnecting. Note: always inspect the rubber hose and port for blockage before condemning the switch itself.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8MEA048070ACJA packaged gas unit. Also fits a wide range of Carrier, Bryant, and Payne furnaces and packaged units sharing the same inducer and pressure switch specification — verify the W.C. rating on your existing switch before ordering.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8MEA048070ACJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8MEA048070ACJA. 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 PG8MEA048070ACJA?
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?
