OEM Carrier LP Gas Pressure Switch for Model PG8JAA060090AGJA

This OEM LP gas pressure switch is the factory-specified replacement for the Carrier PG8JAA060090AGJA packaged gas unit. The pressure switch proves that the inducer motor has established adequate draft before allowing ignition — a critical safety interlock in the furnace control sequence. When this switch fails or drifts out of calibration, the control board cannot confirm proper venting, triggering a hard lockout before the burners ever fire. Common symptoms include the inducer running continuously with no ignition attempt, a flashing fault code indicating an open pressure switch, or a furnace that starts then immediately shuts off.

  • Specs: LP (Propane) Gas Pressure Switch | Cut-out set point: 6.5" W.C. | SPST configuration | OEM part numbers: HK02LB008 (primary), HK06WC091, HK06WC100 (w/ bracket) | Cross-reference: GFS3451-4036
  • OEM vs Generic: This is a genuine Carrier factory-authorized part matched to the exact W.C. rating for the PG8JAA060090AGJA. Aftermarket pressure switches frequently carry wider tolerances that can cause nuisance lockouts or — more dangerously — allow ignition under insufficient draft conditions.
  • Install difficulty: 2/5 — Shut off power and gas before servicing. Tools needed: flathead screwdriver, needle-nose pliers, and a manometer to verify switch operation after install. Note: HK06WC100 variant includes a mounting bracket — confirm your bracket configuration before ordering.
  • Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PG8JAA060090AGJA packaged gas/electric unit. This listing covers three OEM part numbers in the same switch family — HK02LB008 (standard), HK06WC091, and HK06WC100 (with bracket). Verify your existing switch's W.C. rating and bracket configuration from the unit's data plate or wiring diagram before ordering. Questions about fitment? Our HVAC parts specialists confirm compatibility before you buy — same-day shipping on all stocked items.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8JAA060090AGJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8JAA060090AGJA. 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 PG8JAA060090AGJA?
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.
