The pressure switch is a critical safety component that proves inducer motor operation by detecting the negative pressure (draft) created in the flue system before allowing ignition to proceed. When this switch fails or sticks, the furnace control board receives no confirmation that the inducer is running — locking out the heating cycle entirely. Common symptoms include a furnace that powers on, runs the inducer motor briefly, then shuts down without ever reaching ignition, or a system that flashes a pressure switch fault code on the control board LED.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Specs:\u003c\/strong\u003e OEM Carrier Pressure Switch Assembly | Includes factory-mounted bracket for direct bolt-in installation | W.C.
