The pressure switch is a safety device that monitors negative pressure (draft) created by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When the switch fails — or the port becomes blocked — the furnace will lock out before ignition, often flashing a fault code for \"pressure switch stuck open\" or \"pressure switch stuck closed.\" Symptoms include no heat, a cycling inducer with no ignition, or a continuous inducer run with no burner flame.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-rated W.C.
