OEM Carrier Gas Pressure Switch HK02LB008 / HK06WC091 for Model PG8JAA036110AEJA

This is the factory-specified OEM gas pressure switch for the Carrier PG8JAA036110AEJA packaged gas unit. The pressure switch is a critical safety device that proves the inducer (draft blower) is operating correctly before allowing the gas valve to open and ignition to begin. When this switch fails or sticks open, the furnace will attempt to start, fail to advance past the inducer proving stage, and enter a hard lockout — leaving you with no heat. Common symptoms include the inducer running continuously with no ignition, a flashing fault code indicating a pressure switch error, or repeated restart attempts without firing.

  • OEM Part Numbers: HK02LB008 (Gas Pressure Switch) | HK06WC091 (Pressure Switch) — both are factory-authorized replacements for the PG8JAA036110AEJA. Confirm your unit's data plate and existing switch markings before ordering.
  • OEM vs Generic: OEM switches are factory-calibrated to exact W.C. (water column) setpoints — critical for safe furnace operation. Generic aftermarket pressure switches often carry wider tolerances, risking nuisance lockouts or, worse, unsafe combustion conditions.
  • Install Difficulty: 2/5 — Disconnect power before beginning. Tools needed: #2 Phillips screwdriver, 1/4" nut driver, multimeter (continuity mode). Label and photograph all hose connections before removal. Swap the rubber pressure hose to the new switch and restore wiring to matching terminals.
  • Warranty & Shipping: 1-year OEM factory warranty. In stock — ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed and factory-matched for the Carrier PG8JAA036110AEJA packaged gas unit. This switch is also used across a broad range of Carrier, Bryant, and Payne gas furnace and packaged unit platforms — verify your unit's existing switch part number against HK02LB008 or HK06WC091 before purchasing.

Frequently Asked Questions

Does this Pressure Switch fit my Carrier PG8JAA036110AEJA?
Yes. This is the factory-specified OEM pressure switch for the Carrier PG8JAA036110AEJA. 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 PG8JAA036110AEJA?
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?
