The pressure switch monitors negative pressure created by the inducer (draft) motor to confirm adequate venting airflow before the control board allows ignition to proceed. When it fails or sticks open, the furnace or packaged unit will lock out prior to ignition — often with a diagnostic fault code indicating a pressure switch or inducer fault. A faulty pressure switch is one of the most common no-heat service calls on Carrier packaged equipment.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 0.18\" W.C.
