The pressure switch proves that the inducer motor has established proper draft before allowing the ignition sequence to proceed. When this switch fails or sticks open, the control board detects an unsafe venting condition and locks out the furnace — resulting in a no-heat call with no ignition attempt and a fault code pointing to a pressure switch fault.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.
