The pressure switch is a critical safety component that proves inducer motor operation before allowing the ignition sequence to proceed. It monitors the negative pressure created by the draft inducer and closes its contacts only when that pressure falls within the correct range. When this switch fails or sticks open, the furnace will lock out on a pressure switch fault — typically before the burners ever light — leaving you with no heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 22\" W.C. close pressure | 7\" W.C. open pressure | 50\" lead wires | 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 switch calibrated to exact factory W.C. thresholds.
