OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8JAA036070ADJA

This is the genuine OEM Carrier pressure switch assembly with mounting bracket, part number HK06WC069, factory-specified for the Carrier PG8JAA036070ADJA gas furnace. The pressure switch is a critical safety device that monitors negative pressure created by the inducer motor to confirm proper venting before allowing ignition. If the switch fails to close — or fails to open — the control board will lock out the heating sequence entirely, leaving you with a furnace that attempts to start but never reaches ignition. Common symptoms include a flashing fault code on the control board, the inducer motor running but burners never lighting, or the furnace cycling off within the first 30 seconds of operation.

• Specs: Single-stage pressure switch assembly | Includes factory mounting bracket | Honeywell-manufactured switch internals | Rated .27" W.C. break / .42" W.C. max make | Direct OEM replacement — no modifications required
• OEM vs Generic: This OEM assembly ships with the factory-matched bracket and pre-calibrated set point. Aftermarket switches often deviate ±15% from the rated W.C. set point, causing nuisance lockouts or, worse, masking genuine venting problems that create carbon monoxide risk.
• Install difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Disconnect the hose port and two wiring terminals, unbolt the old bracket, and reverse the process. Always inspect the pressure port hose for cracks or blockages before installing the new switch.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
