The pressure switch is a critical safety component that monitors the inducer blower's ability to create proper negative draft pressure before allowing the ignition sequence to proceed. When this switch fails — or when a blocked condensate drain, cracked inducer housing, or faulty hose causes it to trip — the furnace or packaged unit will lock out before ignition, leaving you with no heat. Common symptoms include a system that attempts to start, runs the inducer motor briefly, then shuts down with a pressure switch fault code on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK02ZB038 | Factory-calibrated W.C.
