The pressure switch proves that the inducer motor has established proper negative draft pressure before allowing the control board to proceed with ignition. When it fails or sticks open, the furnace or packaged unit will lock out on the first call for heat — no spark, no gas, no flame — leaving you with a cold building and a blinking fault code. Common failure symptoms include the system cycling the inducer motor repeatedly without progressing, or a diagnostic fault code pointing to a pressure switch fault.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" Water Column (W.C.) setpoint | SPST (single-pole, single-throw) | Normally open | Mates with standard 3\/16\" hose barb fitting | OEM factory-matched switching threshold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact W.C. tolerances at the factory. Generic aftermarket switches frequently drift in setpoint, causing nuisance lockouts or — worse — allowing combustion with inadequate draft, which is a safety hazard. This is one part where OEM is strongly recommended.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Power down the unit at the disconnect before beginning. Tools needed: 1\/4\" nut driver or 5\/16\" socket, needle-nose pliers, and a multimeter to verify continuity after installation. Always note the hose routing and wire terminal orientation before removing the old switch. Replace the hose if it shows any cracks or heat damage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty \u0026amp; Shipping:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
