OEM Carrier Draft Pressure Switch 0.18" WC for Model PY3GEAA60130AA

This OEM Carrier draft inducer pressure switch is the factory-specified replacement for the Carrier PY3GEAA60130AA packaged unit. The pressure switch monitors negative pressure created by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or sticks open, the control board cannot verify that the inducer is running and safe combustion airflow is established — resulting in a no-heat condition, furnace lockout, or a system that shuts down before ignition even begins.

• Specs: 0.18" W.C. (water column) setpoint | Draft inducer proving switch | SPST normally-open | Replaces OEM part numbers HK06WC061 and HK06MB061 | Cross-references Honeywell IS20224-5236
• OEM vs Generic: This is a genuine OEM-spec part built to exact factory setpoint tolerance. Off-brand switches often drift from their rated W.C. setpoint, causing nuisance lockouts or — worse — failing to detect a true inducer fault, creating a safety risk.
• Install difficulty: 2/5 — Turn off power and gas supply before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, and a manometer (recommended to verify setpoint post-install). Disconnect the rubber hose port and two electrical terminals, swap the switch, and confirm tubing is fully seated with no cracks.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PY3GEAA60130AA packaged gas/electric unit. This part supersedes the original HK06WC061 and ships as the current HK06MB061.
