OEM Carrier Gas Pressure Switch HK02LB008 for Model PG8JAA060155AGJA

This is the genuine OEM Carrier gas pressure switch (part number HK02LB008), factory-specified for the Carrier PG8JAA060155AGJA packaged gas unit. The pressure switch monitors the negative pressure created by the inducer motor and proves proper draft before allowing the control board to proceed with ignition. When this switch fails or sticks open, the furnace will lock out on a pressure fault — typically before the igniter ever fires — leaving you with no heat. A failed switch may also cause short-cycling or a continuous inducer run with no ignition attempt.

  • Specs: LP / Gas Pressure Switch | Cut-out set point: 6.5" W.C. | SPST configuration | Compatible with air, natural gas, and LP gas applications | Mounts horizontally or vertically
  • OEM vs Generic: This is a factory-matched OEM part. Generic pressure switches frequently carry wider W.C. tolerances that can cause nuisance trips or fail to prove draft reliably — both leading to repeat service calls. The OEM part ensures the precise set-point your control board expects.
  • Install difficulty: 2/5 — Shut off power and gas before servicing. Disconnect the pressure tubing and two-wire harness, swap the switch, and reconnect. Tools needed: 1/4" nut driver, flat-head screwdriver. Always inspect the pressure tubing for cracks or blockages while the switch is off — a plugged port is a common root cause of switch failure.
  • Warranty & Shipping: 1-year OEM factory warranty. Orders placed before 3 PM local time ship same business day from our warehouse.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8JAA060155AGJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8JAA060155AGJA. 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 PG8JAA060155AGJA?
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?
