OEM Carrier Gas Pressure Switch (HK02LB008 / HK06WC091 / HK06WC100) for Model PG8JAA036110AGJA

This OEM Carrier pressure switch is the factory-specified replacement for the Carrier PG8JAA036110AGJA packaged gas/electric unit. The pressure switch proves that the inducer motor has established adequate draft before allowing the control board to proceed with ignition. When it fails — or the hose, port, or diaphragm is compromised — the furnace will lock out during the pre-purge cycle, leaving you with no heat and typically a diagnostic fault code indicating a pressure switch failure.

  • Specs: Cut-out set point: 6.5" WC (inches of water column) | SPST configuration | Suitable for air, natural gas, or LP gas applications | Mounts horizontally or vertically
  • OEM Part Numbers Covered: HK02LB008 (Gas Pressure Switch) | HK06WC091 (Pressure Switch) | HK06WC100 (Pressure Switch w/ Bracket) — all are factory OEM Carrier components for this platform. Note: HK02LB008 has been superseded; direct replacement is HK02MB008.
  • OEM vs Generic: OEM pressure switches are calibrated to exact W.C. setpoints from the factory. Off-brand switches frequently carry ±15% tolerances that cause nuisance lockouts or, worse, allow ignition under unsafe draft conditions. Don't compromise on safety-critical components.
  • Install Difficulty: 2/5 — Disconnect power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, and a manometer (recommended for setpoint verification). Photograph hose routing before disconnecting. Always inspect the rubber sensing hose and port for cracks or blockages before condemning the switch.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered for the Carrier PG8JAA036110AGJA packaged gas/electric unit. Also fits select Bryant and Payne models sharing this pressure switch platform — verify the W.C. rating on your unit's wiring diagram or data plate before ordering. Our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8JAA036110AGJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8JAA036110AGJA. 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 PG8JAA036110AGJA?
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?
