OEM Carrier Gas Pressure Switch HK02LB008 / HK06WC091 for Model PG8MEA060110ABJA

This OEM Carrier gas pressure switch is the factory-specified replacement for the Carrier PG8MEA060110ABJA packaged gas unit. The pressure switch proves that the inducer motor has established proper draft before allowing the ignition sequence to proceed. When this switch fails or sticks open, the control board interprets it as an unsafe flue condition and locks out the furnace — resulting in a no-heat call with the inducer running but no ignition attempt. This part covers two OEM part numbers: HK02LB008 (Gas/LP Pressure Switch, 6.5" W.C. cut-out) and HK06WC091 (SPST Pressure Switch, High Fire), ensuring you receive the correct factory-matched component for your specific unit configuration.

• Specs: Cut-out setpoint: 6.5" W.C. | SPST configuration | Suitable for natural gas and LP applications | Can be mounted horizontally or vertically | Factory-authorized OEM part
• OEM vs Generic: OEM pressure switches are calibrated to exact W.C. tolerances specified by the manufacturer. Generic alternatives often carry wider setpoint variance, risking nuisance lockouts or — more dangerously — failure to detect a true draft loss condition.
• Install difficulty: 2/5 — Shut off power and gas supply before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify switch continuity), and a manometer if recalibration is suspected. Always inspect the rubber hose port for cracks or blockages before swapping the switch.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PG8MEA060110ABJA packaged gas unit. Also fits select Bryant and Payne models sharing the same pressure switch specification — verify your unit's data plate W.C. rating before ordering. Note: HK02LB008 has been superseded by HK02MB008, and HK06WC091 has been superseded by HK06MC110; all are factory-equivalent replacements. Questions about fitment?
