OEM Carrier Pressure Switch Assembly with Bracket HK06WC069 for Model PG8JAA048070ACJA

This is the genuine OEM Carrier pressure switch assembly with mounting bracket, part number HK06WC069, factory-specified for the Carrier PG8JAA048070ACJA gas furnace. The pressure switch is a safety device that monitors negative pressure created by the inducer (draft) motor to confirm proper venting before allowing the ignition sequence to proceed. When the inducer fails to develop adequate draft — or when the switch itself fails — the control board receives no proof signal and locks out the furnace before any gas is released. Common symptoms of a failed pressure switch include the furnace cycling the inducer but never advancing to ignition, a blinking fault code for "pressure switch open," or a furnace that starts briefly and immediately shuts down.

• Specs: Opening set point: -0.27" W.C. | Max make pressure: -0.42" W.C. | Includes factory mounting bracket | Single-stage, normally open configuration | Honeywell/Carrier OEM sensing element
• OEM vs Generic: This factory OEM assembly uses precision-calibrated sensing diaphragms held to exact W.C. tolerances. Aftermarket substitutes frequently drift outside spec, causing nuisance lockouts or — worse — allowing ignition under unsafe draft conditions. OEM is the only choice for a safety-critical component.
• Install difficulty: 2/5 — Power down and confirm inducer is off before disconnecting the pressure hose. Tools needed: 1/4" nut driver, flathead screwdriver, manometer (recommended for post-install verification). Always inspect and clear the rubber sense tube for cracks or blockages before installing the new switch.
• Warranty: 1-year OEM factory warranty on parts. Ships same business day from our warehouse when ordered before 3 PM local time.
