OEM Carrier Pressure Switch with Bracket (HK06NB124) for Model PG9MAA060100AEKA

This is the factory OEM replacement pressure switch for the Carrier PG9MAA060100AEKA gas furnace. The pressure switch is a critical safety and sequencing component — it monitors the negative pressure created by the inducer draft motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails, the furnace will typically lock out before the burners ever light, displaying a pressure switch fault code. Common symptoms include a furnace that runs the inducer motor but never advances to ignition, or a system that short-cycles with repeated fault codes.

• Specs: SPST (Single-Pole, Single-Throw) | 1.81" WC set point | Includes factory mounting bracket | Fits Carrier PG9MAA060100AEKA and over 200 Carrier and Bryant furnace models
• OEM vs Generic: This is a genuine Carrier OEM part, factory-calibrated to the exact pressure differential required by your furnace's heat exchanger and venting system. Generic aftermarket switches often ship with ±10% set-point tolerances that can cause nuisance lockouts or — worse — allow the furnace to fire under unsafe venting conditions.
• Install difficulty: 2/5 — Shut off power and gas before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to confirm switch continuity before reinstallation. Always photograph the hose routing and wiring connections before disconnecting. The included bracket simplifies a drop-in replacement without modification.
• Supersedes obsolete part numbers: HK06NB119, HK06NB120, HK06NB122, HK06NB123, and HK06ZB104 — this is the current active OEM part covering all prior variants.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
