OEM Carrier Dual Pressure Switch Assembly HK06NB020 for Model PG95SAS60080CAAA

This OEM dual pressure switch assembly is the factory-specified replacement for the Carrier PG95SAS60080CAAA 95% AFUE gas furnace. The pressure switch proves that the inducer motor has established proper draft before allowing the ignition sequence to begin. When it fails or sticks open, the control board detects an unsafe draft condition and locks out the furnace — often before a single ignition attempt is made. Symptoms include a furnace that runs the inducer but never advances to ignition, a flashing fault code for open pressure switch, or intermittent no-heat calls that reset after power cycling.

• OEM Part Numbers: HK06NB020 (Dual Pressure Switch Assembly) | HK02LB008 (Gas Pressure Switch) — both covered by this listing. Verify your unit's data plate before ordering.
• OEM vs Generic: OEM switches are factory-calibrated to the exact water column (W.C.) rating required by the PG95SAS60080CAAA heat exchanger and inducer assembly. Off-brand switches with loose W.C. tolerances can allow unsafe ignition conditions or cause nuisance lockouts.
• Install Difficulty: 3/5 — Turn off power and gas before starting. Tools needed: 1/4" nut driver, needle-nose pliers, manometer (recommended to verify W.C. after replacement), and a multimeter to confirm switch continuity. Always inspect the rubber hose port and tubing for cracks or blockages before installing the new switch, as a failed hose is a common root cause of switch failure.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse — order by 3 PM local time.

Compatibility: Designed for the Carrier PG95SAS60080CAAA 95% AFUE gas furnace. Cross-references: HK06NB020, HK02LB008.
