OEM Carrier Pressure Switch HK06WC061 for Model PY3GEAA60115AA

This is the factory OEM replacement pressure switch (part number HK06WC061) for the Carrier PY3GEAA60115AA packaged unit. The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor before allowing the ignition sequence to proceed. If the switch fails to close — or is stuck open or closed — the furnace control board will lock out the heating sequence entirely, resulting in a no-heat call. Common symptoms include the inducer running continuously with no ignition, a blinking fault code indicating a pressure switch error, or a unit that attempts ignition and immediately shuts down.

• Part Number: HK06WC061 | OEM Carrier factory-specified pressure switch | Correct W.C. (water column) rating matched to PY3GEAA60115AA inducer assembly
• OEM vs Generic: OEM pressure switches are calibrated to the exact W.C. trip point required by your unit's inducer. Off-brand substitutes with mismatched trip points can cause nuisance lockouts or, worse, allow combustion without proper venting — a critical safety hazard.
• Install Difficulty: 3/5 — Requires disconnecting the rubber hose port and two electrical terminals. Tools needed: flathead and Phillips screwdriver, needle-nose pliers, and a manometer or U-tube to verify W.C. if diagnosing before replacement. Always shut off power and gas before servicing.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before 3PM local time ship same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PY3GEAA60115AA packaged gas/electric unit. Always cross-reference the W.C. rating printed on your existing switch before installing. If you need help confirming fitment, our HVAC parts specialists are available to verify compatibility before you order — no guesswork required.
