The pressure switch is a normally-open, single-pole single-throw (SPST) safety device that proves the inducer motor is generating sufficient negative draft pressure before the control board advances to ignition. When the diaphragm inside the switch fails or the hose collapses, the furnace locks out before a flame is ever established — often triggering a fault code and leaving the home without heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1.81\" W.C.
