The pressure switch monitors the negative pressure created by the draft inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When it fails or sticks open, the furnace will lock out before ignition — leaving you with a blinking fault code and no heat. A failed pressure switch is one of the most common causes of a furnace that won't start, even when the inducer motor is running normally.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" Water Column (WC) | SPST (Normally Open) | Draft inducer proving switch | Replaces OEM part numbers HK06WC061 and superseding part 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 factory-authorized part, precision-calibrated to 0.18\" WC.
