OEM Carrier Pressure Switch Assembly with Bracket — HK06WC069 for Model PG8MAA066135ABJA

This is the factory OEM pressure switch assembly with integrated mounting bracket (part number HK06WC069), the direct replacement for the Carrier PG8MAA066135ABJA gas furnace. The pressure switch is a critical safety device that monitors negative pressure produced by the inducer motor. When the inducer is running correctly and producing the proper draft, the pressure switch closes and allows the ignition sequence to proceed. A failed or out-of-spec pressure switch will prevent the furnace from advancing past the inducer stage, resulting in a no-heat lockout condition — often indicated by a flashing LED fault code on the control board.

• Part Details: OEM Carrier Pressure Switch Assembly with Bracket | Part# HK06WC069 | Single-stage draft proving switch | Factory-calibrated set point (.27" W.C. break / .42" W.C. max make)
• OEM vs Generic: This is a genuine OEM Carrier component built to exact factory pressure tolerances. Aftermarket switches frequently ship with loose calibration specs, leading to nuisance lockouts or — worse — allowing ignition under unsafe draft conditions. OEM is the only recommended choice for a safety-critical component.
• Install Difficulty: 2/5 — The bracket-mount design simplifies swap-out. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers. Always shut off gas and power before servicing. Inspect and clear the pressure switch hose port and tubing of any moisture or debris before installing the new switch.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
