OEM Carrier LP Gas Pressure Switch HK02LB008 for Model PG8MAA048110AGJA

This OEM gas pressure switch (part numbers HK02LB008, HK06WC091, and HK06WC100) is the factory-specified replacement for the Carrier PG8MAA048110AGJA packaged gas unit. The pressure switch monitors gas supply pressure in the burner assembly and opens or closes the control circuit when the setpoint is reached — proving safe combustion conditions before allowing the sequence of operation to continue. When this switch fails or drifts out of calibration, the furnace will typically lock out on a pressure fault, refuse to ignite, or cycle off immediately after a heat call without delivering warm air.

  • Specs: 6.5" W.C. cut-out pressure | LP (propane) gas application | SPST normally open | Fits air, natural gas, and LP gas configurations | Mounts horizontally or vertically
  • OEM vs Generic: This is a genuine Carrier OEM switch factory-set to the exact 6.5" W.C. trip point. Aftermarket switches often have looser calibration tolerances that can cause nuisance lockouts or — more dangerously — allow operation outside safe pressure bounds.
  • Install Difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers, and a manometer to verify pressure post-install. Photo all wiring connections before disconnecting. Note: HK06WC100 variant includes a mounting bracket for drop-in replacement convenience.
  • Warranty & Shipping: 1-year OEM manufacturer warranty. Orders placed before cut-off ship same business day from our warehouse. Cross-references: HK02LB008 (primary), HK06WC091 (pressure switch), HK06WC100 (pressure switch with bracket).

Compatibility: Engineered as a direct OEM fit for the Carrier PG8MAA048110AGJA packaged gas unit. Also fits select Bryant and Payne models sharing the same pressure switch specification — verify the 6.5" W.C. LP rating and OEM part number on your unit's wiring diagram or data plate before ordering. Not sure it fits? Our team verifies fitment before you order — contact us today.

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?

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.
