OEM Carrier Gas Pressure Switch HK02LB008 for Model PG8JEA048070ACJA

This is the factory OEM replacement gas pressure switch for the Carrier PG8JEA048070ACJA gas furnace, carrying OEM part numbers HK02LB008 and cross-reference HK06WC091. The pressure switch is a critical safety component that monitors the negative pressure (vacuum) produced by the draft inducer motor. If the inducer fails to reach the correct RPM — or if the flue, condensate drain, or hose has a blockage — the pressure switch will not close, preventing the furnace from advancing to the ignition stage. The most common symptom of a failed pressure switch is a furnace that attempts to start, the inducer runs, but the system locks out before the igniter ever glows.

  • Specs: SPST (Single-Pole Single-Throw) configuration | Factory-calibrated W.C. (water column) setpoint | Honeywell-manufactured Factory Authorized Part | Compatible with natural gas and propane applications on the PG8JEA048070ACJA
  • OEM vs Generic: OEM pressure switches are calibrated to exact water-column specifications required by your furnace's inducer and heat exchanger design. Generic alternatives often use broader tolerances that can cause nuisance lockouts or, worse, fail to detect a true venting problem — a serious safety risk.
  • Install difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: flathead screwdriver, needle-nose pliers, manometer (recommended to verify switch setpoint after install). Inspect rubber hose and condensate trap before replacing the switch, as a blocked drain is the #1 cause of pressure switch faults.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8JEA048070ACJA gas furnace. Cross-references OEM part numbers HK02LB008 and HK06WC091. Always verify the W.C. rating printed on your existing switch before ordering to ensure an exact match. Have questions about fitment?

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8JEA048070ACJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8JEA048070ACJA. 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 PG8JEA048070ACJA?
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?
