OEM Carrier Pressure Switch with Bracket HK06NB124 for Model PG9MAB024060LBSA

This is the factory OEM replacement pressure switch with bracket for the Carrier PG9MAB024060LBSA gas furnace. The pressure switch monitors negative pressure created by the inducer motor to confirm proper draft before allowing the ignition sequence to proceed. When this switch fails, your furnace will lock out before ignition — typically displaying an error code indicating a pressure switch fault — leaving you with no heat. A failed inducer motor, cracked hose, or blocked condensate drain can also trigger this switch, so always inspect those components before replacing.

• Specs: -1.65" W.C. set point | SPST (Single-Pole, Single-Throw) | Includes factory mounting bracket | OEM Part Number HK06NB124 | Supersedes HK06NB119, HK06NB120, HK06NB122
• OEM vs Generic: This is the genuine Carrier OEM switch — factory-calibrated to the exact W.C. set point for your PG9MAB024060LBSA. Aftermarket switches often carry wider pressure tolerances, risking nuisance lockouts or unsafe operation. Do not compromise on draft-proving safety controls.
• Install Difficulty: 2/5 — Shut off power and gas before starting. Tools needed: 1/4" nut driver, flat-head screwdriver, phone camera (to photograph hose and wiring routing). Disconnect the pressure hose, swap the bracket-mounted switch, reconnect wiring spades and hose. Cycle the furnace and confirm normal ignition sequence.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
