The pressure switch is a critical safety component that monitors negative pressure created by the inducer motor to confirm it is operating at the correct RPM and establishing proper draft before allowing ignition. When this switch fails, the control board cannot verify safe venting conditions and will lock out the heating sequence entirely — leaving you with a no-heat call.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.
