The pressure switch monitors negative pressure created by the induced draft motor to confirm that combustion gases are properly venting before the ignition sequence is allowed to proceed. When it fails or sticks open, the control board cannot verify inducer operation and will lock out the furnace — leaving you with no heat and often a blinking fault code indicating a pressure switch error.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" Water Column (W.C.) | SPST — Normally Open | Replaces OEM part# HK06WC061 (superseded by HK06MB061) | Also replaces Honeywell IS20224-5236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, factory-calibrated to the exact 0.18\" W.C. trip point required by the \u003cstrong\u003ePY4GPAA42060AA\u003c\/strong\u003e.
