Pressure switches monitor inducer motor operation by proving that proper draft pressure is established before allowing ignition to proceed. When either switch fails — or when its sensing port, tubing, or hose becomes blocked — the control board interprets an unsafe condition and locks out the ignition sequence entirely. Common symptoms include a furnace that attempts to start but stops before the burners light, a blinking fault code indicating a pressure switch issue, or an inducer motor that runs continuously with no heat output.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part numbers HK02ZA395 (High Pressure Switch) and HK02ZB028 (Low Pressure Switch) | Factory-calibrated W.C.
