The pressure switch is a critical safety component that monitors the negative air pressure created by the induced draft blower motor. Once the inducer reaches proper speed and draft is confirmed, the pressure switch closes and signals the control board to proceed with ignition. When this switch fails — or when tubing cracks, the inducer slows, or the flue becomes blocked — the switch stays open, and your system locks out before ever attempting to light. The result: no heat, a blinking fault code, and a call to the technician.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK02ZB038 | Factory-rated W.C.
