OEM Carrier Gas Pressure Switch 6.5" WC for Model PG8JEA048070ABJA

This OEM Carrier gas pressure switch — covering part numbers HK02LB008 (Gas Pressure Switch) and HK06WC091 (Pressure Switch) — is the factory-specified replacement for the Carrier PG8JEA048070ABJA packaged gas furnace unit. The pressure switch is a critical safety device that monitors the vacuum created by the draft inducer motor. Before allowing ignition, the furnace control board checks that the pressure switch has closed, confirming the inducer is running at proper speed and that combustion gases will be safely exhausted. When this switch fails, the furnace will typically attempt ignition, fail to prove the inducer, and go into a no-heat lockout — often logging a pressure switch fault code on the control board.

• Specs: 6.5" W.C. cut-out pressure | Compatible with LP (propane) and natural gas applications | SPST configuration | Mounts horizontally or vertically | OEM part numbers: HK02LB008 / HK06WC091
• OEM vs Generic: OEM pressure switches are factory-calibrated to the exact W.C. setpoint required by your PG8JEA048070ABJA. Generic switches often carry wider pressure tolerances, risking nuisance lockouts or — more critically — failure to prove a true inducer fault, creating a flue safety hazard.
• Install difficulty: 2/5 — Shut off gas and power before beginning. Tools needed: 1/4" nut driver, needle-nose pliers, and a manometer or magnehelic gauge to verify setpoint after installation. Photograph all tubing and wiring connections before disconnecting. Swap the rubber hose and two-wire harness connector directly to the new switch.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before 3 PM ship same business day from our warehouse.
