The pressure switch is a critical safety component that monitors the negative pressure (vacuum) created by the induced draft blower to confirm proper venting before allowing the ignition sequence to proceed. When the inducer is running correctly, the switch closes and signals the control board to continue. If the switch fails — or if actual draft pressure is out of spec — the board locks out, and the furnace will not light. Common symptoms of a failed pressure switch include a furnace that attempts to start but halts before ignition, a flashing fault code indicating a pressure switch fault, or a unit that short-cycles continuously without producing heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.27\" W.C. break \/ 0.42\" W.C. max make | Single-stage | Honeywell IS20205-4021 sensing element | Includes pre-attached mounting bracket for direct OEM fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a factory-genuine Carrier part (HK06WC069) with exact W.C. calibration.
