The pressure switch monitors gas supply pressure and acts as a safety device — if inlet LP pressure falls outside the acceptable operating range, the switch opens the control circuit and locks out the furnace, preventing unsafe combustion. A failed pressure switch typically causes a \u003cstrong\u003eno-heat condition\u003c\/strong\u003e, repeated ignition lockout, or a fault code indicating pressure switch failure.
