OEM Carrier LP Gas Pressure Switch HK02LB008 / HK06WC091 for Model PG8MEA024045ACJA

This is the factory OEM LP gas pressure switch for the Carrier PG8MEA024045ACJA packaged gas/electric unit. The pressure switch is a critical safety device that monitors the negative pressure (vacuum) created by the draft inducer motor before allowing ignition to proceed. If the inducer fails to generate sufficient vacuum — or if the switch itself fails — the furnace control board will lock out the ignition sequence entirely, resulting in a no-heat call. A failed pressure switch typically causes the system to attempt ignition and immediately abort, with a diagnostic fault code indicating a pressure switch fault or open pressure switch condition.

• OEM Part Numbers: HK02LB008 (LP Gas Pressure Switch) | HK06WC091 (Pressure Switch High Fire) — both covered by this listing for the PG8MEA024045ACJA
• Specs: Cut-out pressure set at 6.5" W.C. | SPST configuration | Suitable for LP/propane gas applications | Mounts horizontally or vertically | Factory-matched to Carrier/Bryant/Payne furnace and packaged unit platforms
• OEM vs Generic: OEM pressure switches are calibrated to exact W.C. setpoints at the factory. Off-brand switches frequently drift outside specification, causing nuisance lockouts or, worse, failing to trip during an actual inducer fault — a safety risk. Always replace with OEM on gas appliances.
• Install Difficulty: 2/5 — Shut off gas and power before servicing. Locate the switch on the inducer housing, disconnect the two wiring terminals and vacuum hose, and swap in the new switch. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify continuity pre-install). Total job typically under 20 minutes for a qualified technician.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8MEA024045ACJA packaged gas/electric unit. Also fits select Bryant and Payne models sharing the same inducer and pressure switch platform. Always verify the W.C. rating and part number stamped on your existing switch before ordering. Our parts team is available to confirm fitment — contact us before you order if you have any questions.
