OEM Carrier Draft Inducer Pressure Switch 0.18" WC for Model PY3GEAA60130NA

This OEM draft inducer pressure switch is the factory-specified replacement for the Carrier PY3GEAA60130NA packaged unit. The pressure switch monitors negative pressure created by the inducer blower motor to confirm safe venting conditions before allowing the ignition sequence to proceed. When this switch fails or sticks closed/open, the furnace will lock out before ignition — often with a 3-flash or pressure-fault error code — leaving you with no heat.

• Specs: 0.18" Water Column (W.C.) rating | Normally open | Single-port draft proving switch | Replaces OEM part HK06WC061 (superseded by HK06MB061) | Also replaces Honeywell IS20224-5236
• OEM vs Generic: This OEM-spec switch is calibrated to the exact 0.18" W.C. set-point required by your Carrier unit. Off-brand switches with loose tolerances can trip prematurely or fail to trip at all — causing nuisance lockouts or, worse, unsafe operation.
• Install difficulty: 2/5 — Shut off power and gas before servicing. Locate the switch on the inducer housing, disconnect the rubber tubing and 2-wire connector, and swap in the new switch. Tools needed: flathead screwdriver, needle-nose pliers. Always confirm tubing is free of blockages before replacing the switch.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PY3GEAA60130NA packaged unit. Also fits select Bryant and Payne models sharing the same 0.18" W.C. pressure switch specification. Verify W.C. rating on your existing switch before ordering — incorrect W.C. ratings will cause misdiagnosis. Questions about fitment? Our HVAC parts specialists verify compatibility before you order.
