The pressure switch is a critical safety device that monitors the negative pressure generated by the inducer draft motor. It confirms that proper airflow and venting conditions exist before allowing the ignition sequence to proceed. When this switch fails or sticks, the furnace will lock out before ignition — often displaying a fault code — leaving you with no heat until the issue is resolved.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-rated water column (W.C.) pressure setpoint | Single-port or dual-port configuration factory-matched to Carrier LC350TM400559 | 24V control circuit compatible | Durable diaphragm construction for long service life\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part, manufactured to exact factory pressure calibration tolerances. Aftermarket pressure switches frequently carry imprecise W.C. ratings that can cause nuisance lockouts or — more critically — fail to detect unsafe venting conditions, posing a carbon monoxide risk.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Disconnect power and gas before servicing.
