The pressure switch proves that the inducer motor has created adequate negative pressure in the flue system before allowing the ignition sequence to proceed. When this switch fails or its diaphragm becomes stiff or ruptured, the control board cannot confirm proper draft, and the furnace will lock out — typically displaying a pressure switch fault code — before the burners ever fire. If your Carrier furnace is shutting down before ignition with a draft or pressure fault code, this switch is the most common culprit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e SPST (Single-Pole, Single-Throw) | Set Point: -1.65\" W.C. | 1\/4\" barb port connection | Normally Open | Includes factory mounting bracket | Manufacturer: Honeywell for Carrier\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 W.C. tolerances.
