The pressure switch is a critical safety device that monitors the negative pressure (vacuum) created by the draft inducer motor. If the inducer fails to reach the correct RPM — or if there is a venting blockage, cracked hose, or diaphragm failure — the pressure switch will not close, preventing the furnace from proceeding to ignition. A faulty pressure switch typically causes the furnace to lock out before the ignition sequence begins, leaving the home without heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e SPST (Single-Pole, Single-Throw) | High-Fire configuration | Factory Authorized Part manufactured by Honeywell | Rated for Carrier 80% AFUE gas furnace applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part built to exact factory pressure set-points.
