The pressure switch monitors negative pressure created by the inducer motor during the pre-purge cycle. If the switch fails to close — or fails to open — the integrated furnace control board will lock out ignition, leaving you with no heat. Common symptoms include a furnace that starts the inducer but never advances to ignition, or a system that throws a pressure switch fault code on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.
