OEM Carrier Pressure Switch HK06WC061 for Model PY3GNAA24040NA

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier PY3GNAA24040NA gas furnace. The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor. It confirms that proper venting airflow exists before allowing the control board to advance the ignition sequence. When this switch fails — or when the hose, port, or inducer itself causes it to read incorrectly — the furnace will lock out prior to ignition, often displaying a pressure switch fault code and leaving your home without heat.

• Specs: OEM part number HK06WC061 | Factory-calibrated W.C. (water column) set point | Single-port design | 24V control circuit rated | Direct OEM fit, no modification required
• OEM vs Generic: This is a genuine Carrier OEM pressure switch, precision-calibrated to the exact W.C. rating required by the PY3GNAA24040NA. Generic substitutes are often rated at approximate set points, risking nuisance lockouts or, worse, unsafe venting conditions that a mis-calibrated switch fails to detect.
• Install Difficulty: 2/5 — A straightforward swap for experienced DIYers or technicians. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm continuity before and after). Always shut off gas and power before servicing. Inspect the rubber hose and inducer port for blockages or cracks — these cause most pressure switch failures and should be replaced if damaged.
• Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day from our warehouse when ordered before cutoff.
