OEM Carrier Pressure Switch w/ Bracket (HK06NB124) for Model PG9MAB024060ABSA

This OEM pressure switch with mounting bracket is the factory-specified replacement for the Carrier PG9MAB024060ABSA gas furnace. The pressure switch proves that the inducer blower has generated adequate negative pressure before the control board allows the ignition sequence to proceed. When the diaphragm weakens or the switch contacts fail, the furnace will lock out before ignition — typically displaying a pressure switch fault code — and no heat will be produced. A failed switch is one of the most common furnace no-heat diagnoses.

• Specs: SPST (Single-Pole, Single-Throw) | Set Point: -1.65" W.C. | 1.81" W.C. rated | Normally Open | Includes factory mounting bracket | Manufactured by Honeywell for Carrier
• OEM vs Generic: This is the genuine OEM part with the factory-calibrated diaphragm set point. Aftermarket switches frequently ship with loose W.C. tolerances that cause nuisance lockouts or, worse, allow ignition under unsafe draft conditions.
• Install difficulty: 2/5 — Power down the furnace at the breaker before beginning. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers. Photograph all hose and wiring connections before removal. Note port orientation (+/−) when routing the pressure hose to the new switch. Discharge any residual pressure from the inducer housing before disconnecting hoses.
• Warranty: 1-year OEM manufacturer warranty against defects. Supersedes obsolete part numbers HK06NB119, HK06NB120, HK06NB122, and HK06NB123. Ships same business day from our warehouse.
