The pressure switch monitors the negative pressure generated by the inducer motor to confirm proper draft before allowing ignition to proceed. When it fails — or when the hose, port, or diaphragm degrades — the control board cannot verify inducer operation, and the furnace will lock out before the burners ever light. Common symptoms include a no-heat call with the inducer running but the igniter never energizing, or a steady pressure switch fault code on the board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e -0.33 W.C.
