The pressure switch is a safety device that monitors negative pressure created by the inducer (draft) motor to confirm proper venting before allowing the ignition sequence to proceed. When it fails or develops a leak, the furnace control board cannot verify safe combustion conditions and will lock out — typically resulting in a no-heat fault code pointing to a pressure switch open condition. The furnace may attempt to start, run the inducer briefly, and then shut down without ever reaching ignition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e .33 W.C.
