The pressure switch is a critical safety and sequencing component — it monitors negative pressure produced by the inducer blower motor to confirm proper venting before allowing the ignition sequence to proceed. When the switch fails or sticks, the control board receives no confirmation signal and the furnace will lock out, resulting in a no-heat call with a flashing fault code indicating a pressure switch or inducer fault.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e .27\" W.C. break \/ .42\" W.C. max make | Single-stage | Includes factory mounting bracket | Honeywell IS20205-4021 internals | Genuine OEM assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM assembly includes the factory-matched bracket and uses exact W.C.
