The pressure switch monitors negative pressure created by the inducer motor to confirm safe venting conditions before allowing the ignition sequence to proceed. When the switch fails — or when a blocked flue, cracked pressure tubing, or worn inducer creates insufficient draft — the control board receives no proof signal and the furnace enters a lockout, producing a no-heat call with no ignition attempt.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.
