OEM Carrier Gas Pressure Switch HK02LB008 / HK06WC091 for Model PG8JEA048090ABJA

This is the genuine OEM Carrier gas pressure switch for the Carrier PG8JEA048090ABJA packaged gas unit. Sold under part numbers HK02LB008 (Gas Pressure Switch) and HK06WC091 (Pressure Switch), this component monitors the gas supply pressure and signals the integrated furnace control board to allow or interrupt ignition. When it fails — or when gas pressure falls outside the factory threshold — the board issues a lockout, leaving you with no heat and a flashing fault code. If your unit attempts ignition and shuts down immediately without firing, or never advances past the inducer pre-purge stage, a faulty pressure switch is one of the first components to test.

  • Specs: LP (propane) gas pressure switch | Cut-out pressure: 6.5 in W.C. | Factory-calibrated for Carrier PG8JEA048090ABJA packaged units | Replaces both HK02LB008 and HK06WC091
  • OEM vs Generic: This is the factory-matched OEM part, engineered to Carrier's exact pressure set point. Aftermarket substitutes often ship with uncalibrated diaphragms that drift over time, causing nuisance lockouts or — worse — unsafe operation.
  • Install Difficulty: 2/5 — Shut off gas and disconnect power before beginning. Tools needed: ¼" nut driver, flathead screwdriver, manometer (recommended for post-install verification), and a leak-detection solution. Photograph hose routing and wiring before disconnecting. Swap the vacuum hose and two-wire harness, then verify operation through a full heat call.
  • Warranty & Shipping: 1-year OEM factory warranty against defects. In-stock units ship same business day from our warehouse. Note: HK02LB008 is superseded — confirm your replacement part number with our team if your unit requires the updated HK02MB008 revision.

Compatibility: Designed for the Carrier PG8JEA048090ABJA packaged gas/electric unit. Also fits select Bryant and Payne packaged units sharing the same pressure switch specification — verify your data plate and OEM part number before ordering. Our fitment team is available to confirm compatibility before you check out. Order now and receive same-day shipping on qualifying in-stock orders.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8JEA048090ABJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8JEA048090ABJA. 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 PG8JEA048090ABJA?
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?
