OEM Carrier Dual Pressure Switch Assembly w/Bracket HK06NB017 for Model PG9UAA060120AASA

This is the OEM factory-specified Dual Pressure Switch Assembly with Bracket (part# HK06NB017) for the Carrier PG9UAA060120AASA packaged gas furnace. The pressure switch is a critical safety component that monitors negative pressure (draft) created by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When one or both switches fail, the control board detects an open pressure switch circuit and locks out the furnace — resulting in a no-heat call with a blinking fault code indicating a pressure switch error. This dual-switch assembly replaces both switches simultaneously and comes pre-mounted on the OEM bracket for a direct drop-in installation.

• Specs: Dual pressure switch assembly | Factory-matched W.C. (water column) set points | Pre-mounted on OEM bracket | Honeywell-manufactured (cross-ref: BA20203) | Direct OEM replacement for Carrier PG9UAA060120AASA
• OEM vs Generic: OEM switches are calibrated to exact W.C. thresholds required by your furnace's control board. Off-spec generic switches can trip too early or too late, causing nuisance lockouts or — more dangerously — failing to detect a venting fault.
• Install difficulty: 3/5 — Requires disconnecting low-voltage wiring harness connectors and flexible tubing from each switch port. Tools needed: flathead screwdriver, needle-nose pliers, phone camera (photograph all hose and wire connections before removal). Confirm inducer motor performance before replacing switch — a weak inducer is the #1 root cause of pressure switch failure.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3 PM local time.
