The pressure switch proves that the induced draft blower has established proper airflow before allowing the ignition sequence to proceed. When it fails — or when the diaphragm stiffens or the hose cracks — the furnace control board detects an open switch circuit and locks out before any ignition attempt, often displaying a fault code. The result: no heat, a flashing LED error code, and a cold home.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e -1.65\" W.C.

Aftermarket pressure switches often carry wider trip-point tolerances that can cause nuisance lockouts or, worse, allow marginal combustion airflow — both of which the OEM part is engineered to prevent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — A straightforward swap for anyone comfortable working inside a furnace cabinet. Tools needed: 1\/4\" nut driver, flat-head screwdriver, and a smartphone camera. Always photograph the existing hose routing and wiring before disconnecting anything. Power off and allow the inducer to cool before beginning.
