The pressure switch monitors negative pressure generated by the inducer motor during each heating cycle. When the inducer achieves proper draft, the switch closes and signals the control board to advance to ignition. A failed or stuck-open pressure switch causes the furnace to lock out before ignition — commonly displayed as a fault code — leaving you with no heat. Replacing it with the correct OEM part restores precise pressure sensing and safe furnace operation.\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 | Includes factory mounting bracket | Manufactured by Honeywell for Carrier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part engineered to exact factory tolerances. Generic aftermarket switches often carry wider set-point tolerances (±0.10\" W.C. or more), which can cause nuisance lockouts or — more dangerously — allow furnace operation under unsafe draft conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Power down the furnace at the disconnect and thermostat before starting.
