OEM Carrier Pressure Switch with Bracket HK06NB124 for Model PG9MAA060120AEKA

This is the genuine OEM replacement pressure switch with mounting bracket for the Carrier PG9MAA060120AEKA gas furnace. The pressure switch is a safety device that proves the inducer (draft) motor is running and creating adequate negative pressure before allowing the ignition sequence to proceed. When this switch fails or becomes stuck open, the furnace control board will halt the startup cycle — typically logging an error code — and you'll have no heat. Common symptoms include the inducer motor spinning normally but the furnace locking out before spark or gas valve activation.

• Specs: -1.65" W.C. set point | SPST (Single-Pole, Single-Throw) | Includes factory mounting bracket | Supersedes HK06NB119, HK06NB120, and HK06NB122
• OEM vs Generic: This OEM part is precision-calibrated to the exact W.C. rating required by your Carrier furnace control board. Generic switches frequently carry ±10–15% W.C. tolerances, which can cause nuisance trips or fail to protect against a true blocked flue — a potential safety hazard.
• Install difficulty: 2/5 — Turn off gas and 120V power before beginning. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers. Label and photograph hose connections before removal. Replace any deteriorated rubber hose tubing at the same time to prevent a callback.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
