OEM Carrier Pressure Switch Assembly with Bracket (HK06WC069) for Model PG8JAA066110ADJA

This is the genuine OEM pressure switch assembly for the Carrier PG8JAA066110ADJA gas furnace. The pressure switch proves that the inducer motor is operating and generating adequate negative draft pressure before the control board allows the ignition sequence to proceed. When the switch fails — whether stuck open or stuck closed — the furnace control board detects the fault and locks out the unit, resulting in a no-heat call. Common symptoms include the inducer motor running continuously with no ignition attempt, a flashing fault code indicating a pressure switch error, or the furnace cycling off within the first 30 seconds of a heat call.

• Part Number: HK06WC069 | Includes factory-matched mounting bracket | Direct OEM replacement — no modifications required
• OEM vs Generic: This is a genuine Carrier factory part, calibrated to the exact water column (W.C.) set-point required by the PG8JAA066110ADJA control board. Aftermarket switches often carry ±5–10% W.C. tolerance, which can cause nuisance lockouts or — worse — allow the furnace to operate with inadequate draft, creating a carbon monoxide risk.
• Install Difficulty: 2/5 — Straightforward swap on the inducer housing. Tools needed: #2 Phillips screwdriver, 1/4" nut driver, and needle-nose pliers for the vacuum hose barb. Always cycle power off at the breaker before starting. Confirm draft hose routing matches the original before securing the bracket.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
