The pressure switch monitors negative pressure created by the induced draft motor to confirm safe venting conditions before allowing ignition to proceed. When it fails, the control board cannot verify that the inducer is operating correctly, resulting in a no-heat condition, repeated lockout, or a fault code indicating a stuck-open or stuck-closed pressure switch. Replacing it with a genuine OEM part ensures the exact water column (W.C.) rating is maintained for safe and reliable operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number HK06WC061 | Factory W.C. rating matched to PY4GEAA60090AA | Single-port diaphragm-type pressure switch | 24V control circuit compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM pressure switch. Generic aftermarket switches often carry wider W.C. tolerances, which can cause nuisance trips, failed ignition sequences, or — more critically — allow ignition under unsafe draft conditions.
