OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8MAA048070ACJA

This is the genuine OEM replacement Pressure Switch Assembly with Bracket (part number HK06WC069) for the Carrier PG8MAA048070ACJA gas furnace. The pressure switch is a critical safety component that monitors negative pressure produced by the inducer draft motor. Before the control board allows the ignition sequence to proceed, the pressure switch must close and confirm that the inducer is operating correctly and that the flue/vent path is unobstructed. When this switch fails or sticks open, the furnace locks out on a pressure switch fault — resulting in a no-heat call with a blinking LED fault code typically indicating an open pressure switch circuit.

• Specs: Factory-matched pressure switch assembly | Includes integrated mounting bracket | Rated for single-stage 80% AFUE gas furnace application | Switch rating: .27" W.C. break / .42" W.C. max make | Compatible with Honeywell IS20205-4021 internal switch
• OEM vs Generic: This OEM part is manufactured to exact Carrier factory tolerances. Aftermarket alternatives often carry ±15% W.C. deviation, which can cause nuisance lockouts or — more dangerously — fail to detect a true blocked flue condition. Trust OEM for safety-critical components.
• Install difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers, and a manometer or digital magnahelic gauge for post-install verification. Inspect the hose from the inducer to the switch for cracks or blockages before replacing the switch.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3 PM local time.
