It confirms proper venting and inducer draft at both the low-fire and high-fire stages before allowing ignition. If the switch fails or is out of calibration, the furnace locks out with pressure-switch fault codes and will not fire — a common no-heat cause.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 11177113\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetpoints:\u003c\/strong\u003e -0.30\" W.C. and -0.75\" W.C.
