OEM Carrier Pressure Switch Assembly w/Bracket for Model PG8JAA060155ADJA

This is the factory OEM replacement Pressure Switch Assembly with Bracket (Part# HK06WC069) for the Carrier PG8JAA060155ADJA packaged gas furnace. The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor. It verifies that proper venting airflow is established before allowing the control board to initiate the ignition sequence. When this switch fails or drifts out of calibration, the furnace will lock out — typically with a blinking fault code indicating a pressure switch or inducer fault — and no heat will be produced. Common failure symptoms include the furnace starting the inducer but refusing to advance to ignition, intermittent heating lockouts on cold days, or a stuck-open/stuck-closed switch reading on a multimeter.

• Specs: Pressure Switch Assembly with integrated mounting bracket | Factory-calibrated W.C. (water column) rating matched to the PG8JAA060155ADJA inducer and heat exchanger | Pre-assembled bracket for direct bolt-in replacement | OEM Part# HK06WC069
• OEM vs Generic: This is a genuine Carrier OEM component manufactured to exact water-column pressure thresholds. Aftermarket substitutes frequently use looser trip-point tolerances that can cause nuisance lockouts, fail to detect true venting blockages, or allow unsafe operation — making OEM the strongly preferred choice for any safety-rated component.
• Install Difficulty: 3/5 — Requires disconnecting low-voltage wiring harness connectors and a rubber vacuum/pressure hose from the inducer port. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify switch continuity before and after installation. Always power down and disconnect gas supply before servicing. Consult the unit's wiring diagram (located inside the furnace cabinet door) for reference.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed by 3 PM local time ship same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed and factory-spec'd for the Carrier PG8JAA060155ADJA packaged gas furnace. Always cross-reference the OEM part number HK06WC069 and the W.C. rating on your existing switch against your unit's data plate before ordering. Have questions about fitment?
