OEM Carrier Dual Pressure Switch Assembly HK06NB020 for Model PG92SBS60080CBAA

This OEM Dual Pressure Switch Assembly (part number HK06NB020) is the factory-specified replacement for the Carrier PG92SBS60080CBAA 92% AFUE gas furnace. The pressure switch is a safety device that monitors negative pressure (draft) created by the inducer motor — it must close before the ignition sequence can begin. When this switch fails or sticks open, the control board reads a fault and locks out the furnace before a single spark fires, leaving you with a no-heat call. Common symptoms include a flashing fault code for "pressure switch stuck open," a furnace that starts the inducer but never advances to ignition, or intermittent heating on cold, windy days when flue back-pressure fluctuates.

• Part Numbers: Primary OEM part HK06NB020 (Dual Pressure Switch Assembly) | Secondary OEM part HK02LB008 (Gas Pressure Switch) — both are factory-authorized Carrier components for this assembly.
• OEM vs Generic: OEM pressure switches are factory-calibrated to exact water column (W.C.) trip points for the PG92SBS60080CBAA's inducer and heat exchanger. Generic switches often carry ±10–15% W.C. tolerances, risking nuisance lockouts or — more dangerously — failure to detect a cracked heat exchanger.
• Install Difficulty: 3/5 — Shut off gas and power before starting. Tools needed: 1/4" nut driver, flat-head screwdriver, manometer or U-tube to verify W.C. rating, and a multimeter to confirm continuity after install. Check all rubber hose ports for cracks before reconnecting; a leaking hose will cause the same fault code as a failed switch.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Engineered for Carrier PG92SBS60080CBAA packaged gas furnace systems. Always verify the W.C. rating printed on your existing switch before ordering — a mismatched trip point will cause either a no-heat lockout or an unsafe bypass of the proving circuit. Have your model and serial number ready and our fitment team will confirm compatibility before you check out.
