Pressure switches prove that the inducer motor has established adequate airflow through the heat exchanger before the ignition sequence is allowed to proceed. A failed pressure switch will strand the system in a pre-ignition lockout, triggering a fault code and preventing any heat output entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 312926-252 = High Pressure Switch | 312926-258 = Low Pressure Switch | Factory-calibrated W.C.
