OEM Carrier Dual Pressure Switch Assembly HK06NB012 for Model PG95XAT36060AAAA

This OEM dual pressure switch assembly is the factory-specified replacement for the Carrier PG95XAT36060AAAA 95% AFUE two-stage gas furnace. The pressure switch proves that the draft inducer motor has established proper negative pressure inside the heat exchanger before the control board allows the ignition sequence to proceed. A failed pressure switch will cause the furnace to lock out on a fault code before ever reaching the ignition stage — commonly presenting as a "no-heat" call with a flashing LED error code indicating an open pressure switch circuit.

• Specs: OEM Part Numbers: HK06NB012 (Dual Pressure Switch Assembly) and HK02LB008 (Gas Pressure Switch) | Factory W.C. (water column) rating matched to PG95XAT36060AAAA inducer specifications | Single-port and dual-port configurations included in assembly
• OEM vs Generic: OEM pressure switches are calibrated to the exact W.C. trip point specified by Carrier engineering. Generic or off-brand switches frequently carry wider tolerances, risking nuisance lockouts or — more dangerously — failure to detect a true inducer fault, which can compromise heat exchanger integrity.
• Install difficulty: 3/5 — Power down and lock out the furnace before beginning. Tools needed: ¼" nut driver, needle-nose pliers, manometer (recommended to verify W.C. post-install). Carefully label or photograph all hose and wire connections before removing the old switch; misrouted pressure tubing is the most common post-repair error.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Orders placed before cutoff ship the same business day from our warehouse.

Compatibility: Designed specifically for the Carrier PG95XAT36060AAAA packaged 95% AFUE two-stage gas furnace. Always cross-reference the W.C. rating printed on your existing switch and verify both OEM part numbers (HK06NB012 / HK02LB008) against your unit's data plate before ordering. Not sure it fits?
