OEM Carrier LP Gas Pressure Switch HK02LB008 for Model PG8MAA066135AEJA

This OEM Carrier gas pressure switch (part numbers HK02LB008 and HK06WC091) is the factory-specified replacement for the Carrier PG8MAA066135AEJA packaged gas unit. The pressure switch is a critical safety device that proves the inducer motor has created adequate negative pressure in the heat exchanger before allowing the ignition sequence to proceed. When this switch fails or sticks open, the control board cannot confirm draft operation, resulting in a no-heat lockout condition — often displaying a diagnostic fault code indicating a pressure switch error. Symptoms include the inducer blower running continuously with no ignition, or the furnace cycling on and off without ever achieving a flame.

  • Specs: Cutout pressure set at 6.5 in W.C. | LP / Propane gas application | SPST normally open | Fits Carrier, Bryant, and Payne furnaces and packaged units
  • OEM vs Generic: This is a genuine OEM Carrier part manufactured to exact factory pressure tolerances. Aftermarket switches frequently drift outside acceptable W.C. thresholds, causing nuisance trips or — worse — unsafe operation. OEM ensures proper ignition sequencing every time.
  • Install Difficulty: 2/5 — Disconnect power and gas supply before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, and a U-tube manometer to verify inlet gas pressure after installation. Always inspect and clear condensate tubing connected to the switch port before installing the new part.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before 3 PM local time ship same business day from our warehouse.

Compatibility Note: Directly fits Carrier model PG8MAA066135AEJA packaged gas/electric units. This part is also cross-referenced under OEM part number HK06WC091. Verify gas type (LP/Propane) and W.C. rating on your unit's data plate before ordering. Note: HK02LB008 has been discontinued by Carrier; this listing ships the current authorized OEM replacement. Our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8MAA066135AEJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8MAA066135AEJA. 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 PG8MAA066135AEJA?
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?
