OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8JAA048110ADJA

This is the genuine OEM Carrier Pressure Switch Assembly with Bracket (part number HK06WC069), factory-specified for the Carrier PG8JAA048110ADJA gas furnace. The pressure switch is a critical safety device that monitors negative pressure created by the inducer motor. Before each ignition attempt, the control board reads this switch to confirm the inducer is running and that flue gases are being properly vented. If the switch fails — or if the inducer motor, hose, or port is compromised — the switch won't close, and the furnace will lock out before ever reaching ignition, leaving you with no heat.

• Specs: Single-stage draft pressure switch | .27" W.C. break / .42" W.C. max make | Includes factory mounting bracket | Honeywell-manufactured (IS20205-4021 equivalent) | OEM part number HK06WC069
• OEM vs Generic: OEM switches are calibrated to exact W.C. (water column) thresholds for your specific furnace. Generic alternatives frequently deviate from factory setpoints, causing nuisance lockouts or — more dangerously — failing to detect a true venting fault. Always verify the W.C. rating before substituting.
• Install Difficulty: 2/5 — Tools needed: 1/4" nut driver, needle-nose pliers, and a small flathead screwdriver to release the hose barb clip. Disconnect power before servicing. Photograph all hose and wire connections before removal. Before condemning the switch, check the inducer port and rubber hose for cracks, blockage, or moisture — these cause identical symptoms.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
