The pressure switch is a critical safety device that monitors negative pressure created by the inducer\/draft blower motor. Once the inducer reaches the correct speed and airflow, the switch closes to signal the control board that it is safe to proceed with ignition. A failed pressure switch causes the system to lock out before the ignition sequence ever begins — resulting in a no-heat call with a pressure switch fault code displayed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK02ZB038 | Factory-calibrated W.C.

Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter (continuity mode). Always confirm inducer motor and hose integrity before replacing the switch, as a clogged condensate or hose will cause the new switch to fail immediately.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects.
