The pressure switch proves that the inducer motor has created adequate negative pressure in the flue before allowing the ignition sequence to proceed. When this switch fails or sticks open, the control board interprets a blocked or unsafe flue condition and locks out the system — leaving you with no heat and often a diagnostic fault code. Common symptoms include the furnace or packaged unit cycling the inducer but never advancing to ignition, or an immediate lockout on every call for heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.
