OEM Carrier Pressure Switch with Bracket HK06WC090 for Model PG8DAA060135ABJA

This is the factory OEM replacement pressure switch with bracket for the Carrier PG8DAA060135ABJA packaged gas unit. The pressure switch is a critical safety component that monitors negative pressure created by the induced draft blower, confirming proper venting before allowing the ignition sequence to proceed. When this switch fails or becomes out of calibration, the control board receives no "inducer proven" signal — resulting in a no-heat lockout, a blinking fault code, or a furnace that fires briefly and immediately shuts down.

• Specs: Replaces OEM Part# HK06WC090 | Includes factory-matched mounting bracket | Rated to exact water-column (W.C.) specification for Carrier PG8DAA060135ABJA | Single-port hose connection
• OEM vs Generic: OEM pressure switches are calibrated to the precise W.C. rating required by your unit's heat exchanger and venting design. Off-spec generic switches can trip too early or too late — creating nuisance lockouts or, worse, allowing unsafe venting conditions.
• Install Difficulty: 3/5 — Requires disconnecting the rubber hose from the inducer housing, unplugging the wiring harness, and unmounting the bracket. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers. Always power down and verify no gas flow before servicing. Inspect the hose for cracks or blockages before condemning the switch itself.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered by 3 PM local time.
