OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8MAA024070ACJA

This is the genuine OEM Carrier Pressure Switch Assembly with Bracket (part# HK06WC069), the factory-specified replacement for the Carrier PG8MAA024070ACJA gas furnace. The pressure switch is a critical safety device that monitors negative pressure created by the inducer motor. Once the inducer proves adequate draft, the pressure switch closes its contacts and signals the control board to proceed with ignition. A failed or stuck-open pressure switch will cause the furnace to lock out before ignition — leaving you with a no-heat call and a blinking fault code on the control board.

• Specs: Single-stage pressure switch | Rated at -0.27" W.C. break / -0.42" W.C. max make | Includes factory mounting bracket | Honeywell-manufactured (OEM reference: IS20205-4021) | Direct factory fit for PG8MAA024070ACJA
• OEM vs Generic: This OEM assembly ships with the exact-rated W.C. setpoint and pre-attached bracket engineered for this unit. Aftermarket switches frequently carry ±10–15% W.C. tolerance variance, which can cause nuisance lockouts or, worse, fail to detect a true draft failure — a potential safety hazard.
• Install difficulty: 2/5 — Shut off gas and power at the disconnect before starting. Tools needed: Phillips screwdriver, 1/4" nut driver, needle-nose pliers. Disconnect the rubber hose and two wiring terminals, remove the bracket screw, and swap the assembly. Always inspect the hose for cracks or blockage before reinstalling. Typical repair time: 20–30 minutes.
• Warranty & Shipping: 1-year OEM factory warranty against defects. Ships same business day from our warehouse. Free ground shipping on orders over $99.
