Originally sold as \u003cstrong\u003eHK06WC061\u003c\/strong\u003e and superseded by the current OEM part \u003cstrong\u003eHK06MB061\u003c\/strong\u003e, this switch proves that the inducer motor has created sufficient negative pressure before allowing the gas valve to open and the ignition sequence to begin. When it fails — or when its hose, port, or inducer is at fault — the system will lock out before ignition, leaving you with a no-heat call. A failed pressure switch is one of the most common causes of furnace lockout codes.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" Water Column (WC) | SPST (Single-Pole Single-Throw) | Normally Open | Replaces OEM part HK06WC061 | Current OEM cross: HK06MB061 | Also crosses to Honeywell IS20224-5236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM switches are calibrated to exact WC ratings.
