The pressure switch is a critical safety component that monitors negative pressure (inches of water column) inside the flue system to confirm that the draft inducer motor is operating correctly before the ignition sequence is allowed to proceed. When the pressure switch fails, the control board receives no confirmation signal and locks out the system — resulting in a no-heat condition, often accompanied by a fault code indicating an open or stuck pressure switch.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-specified W.C.
