The pressure switch is a critical safety component that monitors system refrigerant or flue pressure to confirm proper operation before allowing the control board to advance through the heating or cooling sequence. A failed pressure switch will cause the system to lock out before ignition, display a fault code, or prevent the inducer motor from completing its proving cycle — leaving you with no heat or no cooling.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e High pressure switch | OEM part number HK02ZA442 | Factory-calibrated W.C.
