OEM Carrier Draft Inducer Pressure Switch 0.18" WC for Model PY3GNAA60130NA — HK06WC061

This is the factory-specified OEM pressure switch for the Carrier PY3GNAA60130NA packaged gas unit. The draft inducer pressure switch monitors negative air pressure created by the inducer motor to confirm safe venting conditions before ignition is permitted. When this switch fails or sticks open, the furnace will lock out before the ignition sequence begins — resulting in a no-heat call with a pressure switch fault code displayed on the control board. Common failure symptoms include the inducer running but the system never advancing to ignition, or intermittent heating loss on cold days when pressure differentials fluctuate.

• Specs: 0.18" Water Column (WC) setpoint | SPST normally-open configuration | Replaces OEM part HK06WC061 (superseded by HK06MB061) | Also cross-references Honeywell IS20224-5236
• OEM vs Generic: This genuine Carrier OEM switch is factory-calibrated to the exact 0.18" WC trip point required by the PY3GNAA60130NA. Generic alternatives often carry ±10–15% pressure tolerances that can cause nuisance lockouts or, worse, allow ignition under unsafe venting conditions.
• Install Difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, and a manometer or magnahelic gauge to verify inducer draft post-installation. Always inspect the rubber pressure hose and hose barb fitting for cracks before reconnecting.
• Warranty: 1-year OEM manufacturer warranty. In-stock orders ship same business day from our warehouse when ordered before cutoff.
