OEM Carrier Pressure Switch with Bracket (HK06NB124) for Model PG9MAA060080AEKA

This OEM pressure switch with integrated mounting bracket is the factory-authorized replacement for the Carrier PG9MAA060080AEKA gas furnace. The pressure switch monitors negative pressure produced by the inducer motor to confirm safe venting conditions before the control board permits ignition. When the diaphragm weakens or the switch fails to close, the furnace locks out before ignition — typically logging a fault code — leaving your home without heat. Replacing it with the correct OEM part restores factory-accurate trip-point calibration and reliable operation.

• Specs: SPST (Single-Pole, Single-Throw) | Set point: -1.65" W.C. | Rated: 1.81" W.C. normally open | Includes factory mounting bracket | Honeywell manufactured, Carrier OEM labeled | Supersedes: HK06NB119, HK06NB120, HK06NB122
• OEM vs Generic: OEM switches are factory-calibrated to the exact water column rating for your furnace. Aftermarket substitutes often carry ±10–15% tolerance on trip points, which can cause nuisance lockouts or — more dangerously — allow ignition under insufficient draft pressure. Don't compromise on a safety-critical component.
• Install difficulty: 2/5 — Inducer must be off and system de-energized before starting. Tools needed: 1/4" nut driver, flathead screwdriver, manometer (for verification), and a phone camera to document hose routing before disconnecting. Match the + and − port labels carefully; one port contains an orifice/flow restrictor — transfer it to the new switch if not pre-installed.
• Warranty: 1-year OEM manufacturer warranty against defects. Orders placed by cutoff ship same business day from our warehouse.
