The pressure switch is a critical safety device that monitors negative pressure created by the draft inducer motor. Once it confirms adequate airflow, it closes its circuit and allows the ignition sequence to proceed. When this switch fails — or if the inducer motor is weak — the control board interprets the open switch as a venting fault and locks out the furnace, leaving you with no heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e .27\" W.C. break pressure | .42\" W.C. max make | Single-stage operation | Honeywell-manufactured (IS20205-4021 cross-reference) | Includes factory mounting bracket for direct bolt-in installation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM assembly includes the factory-calibrated bracket and switch as a matched set.
