The pressure switch is a critical safety component that monitors the negative pressure generated by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or becomes stuck open, the control board cannot verify that combustion gases are being safely exhausted — resulting in a lockout condition, a no-heat call, or a furnace that short-cycles before ignition ever occurs. A faulty pressure switch is one of the most common causes of a furnace that attempts to start but never reaches the ignition stage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Low pressure switch | OEM part number 312926-258 | Factory-calibrated water column (W.C.) rating | Direct plug-in connector and hose port | Engineered for Carrier CH16NA06000GABAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier pressure switch calibrated to the exact W.C. trip point required by the CH16NA06000GABAA. Aftermarket substitutes often carry wider pressure tolerances, which can result in nuisance lockouts or, more dangerously, failure to detect a blocked flue — always use the OEM-specified switch on safety-critical components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Turn off power and gas supply before servicing. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify switch continuity. Disconnect the hose port and wiring harness, swap the switch, and confirm continuity across terminals before restoring power. Check the hose for cracks or clogs while the switch is removed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects.
