The pressure switch is a critical safety component that monitors the draft inducer's negative pressure to confirm proper venting before allowing ignition. When it fails, the control board cannot verify safe inducer operation — resulting in a no-heat lockout, repeated failed ignition attempts, or an error code indicating a stuck-open or stuck-closed pressure switch fault.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Closes at 22\" W.C. | Opens at 7\" W.C. | 50\" lead wires | Low-pressure single-port design | Factory-matched switching threshold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, calibrated to the exact W.C. (water column) rating required by the PH10JA03600GAEAA.
