The pressure switch monitors inducer motor operation by sensing negative air pressure in the vent and combustion air system. When the inducer proves adequate airflow, the switch closes and signals the control board to proceed with ignition. A failed pressure switch typically causes the system to lock out before any ignition attempt — the inducer runs, but the furnace never advances to the heat cycle. Fault codes pointing to pressure switch failure include a stuck-open or stuck-closed switch reading on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-rated W.C.
