OEM Carrier LP Gas Pressure Switch HK02LB008 / HK06WC091 for Model PG8JAA066110AEJA

This OEM Carrier gas pressure switch is the factory-specified replacement for the Carrier PG8JAA066110AEJA packaged gas furnace unit. The pressure switch monitors the negative pressure (vacuum) created by the draft inducer motor to confirm safe flue venting conditions before allowing the gas valve to open and ignition to proceed. When this switch fails or sticks closed/open, the furnace control board will lock out the ignition sequence entirely — leaving you with a no-heat call and a blinking fault code. A failed pressure switch is one of the most common causes of furnace lockout in packaged gas units.

  • OEM Part Numbers: HK02LB008 (Gas Pressure Switch) and HK06WC091 (Pressure Switch High Fire) — both are factory-authorized Carrier OEM components manufactured by Honeywell and cross-compatible with this model
  • Specs: LP / Propane gas application | Cutout pressure: 6.5" W.C. | SPST configuration | Suitable for air, natural gas, or LP gas applications | Horizontal or vertical mounting
  • OEM vs Generic: OEM pressure switches are factory-calibrated to the exact W.C. setpoint required by the Carrier PG8JAA066110AEJA. Generic switches often carry ±15% pressure tolerances, which can cause nuisance lockouts, unsafe venting conditions, or premature heat exchanger stress. Always use OEM on gas-carrying appliances.
  • Install difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, and a manometer or magnehelic gauge to verify inducer vacuum if the problem persists after replacement. Photograph all hose and wiring connections before removal. A licensed HVAC technician is recommended for LP gas appliances.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PG8JAA066110AEJA packaged gas unit. Also fits select Bryant and Payne models sharing this pressure switch specification — verify the W.C. rating on your existing switch's label before ordering. Not sure if this is the right part?

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8JAA066110AEJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8JAA066110AEJA. 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 PG8JAA066110AEJA?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
