The pressure switch is a safety device that monitors negative pressure (draft) created by the inducer motor before allowing the ignition sequence to proceed. When the switch fails — or when a blocked flue, cracked hose, or weak inducer prevents adequate draft — the furnace locks out before reaching ignition, leaving you with no heat. The integrated mounting bracket ensures a clean, rattle-free installation that matches the original factory assembly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-specified W.C.
