OEM Carrier Pressure Switch with Bracket (HK06NB124) for Model PG9MAA024060AEKA

This is the factory OEM replacement pressure switch with mounting bracket for the Carrier PG9MAA024060AEKA gas furnace. The pressure switch is a safety device that monitors negative pressure created by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or its hose becomes cracked or clogged, the furnace will lock out on a pressure switch fault — typically indicated by a flashing LED error code — leaving you with no heat until the issue is resolved.

• Specs: 1.81" W.C. set point | SPST (Single-Pole, Single-Throw) | Includes OEM mounting bracket | Replaces obsolete part numbers HK06NB119, HK06NB120, and HK06NB122
• OEM vs Generic: This OEM switch is factory-calibrated to the exact W.C. set point required by the PG9MAA024060AEKA. Aftermarket switches often carry wider tolerances that can cause nuisance lockouts or — more dangerously — fail to detect a true venting fault.
• Install difficulty: 2/5 — Turn off gas and power before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, and needle-nose pliers. Inspect the rubber hose for cracks before reusing it. Photograph existing wiring and hose routing before removal.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
