The pressure switch is a safety device that monitors negative pressure created by the inducer draft motor — it must close (prove airflow) before the control board will advance the ignition sequence. When this switch fails, the furnace locks out before ignition, often flashing a fault code indicating a pressure switch or inducer error. A failed or stuck switch is one of the most common causes of a no-heat call on Carrier 80% furnaces.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e .33\" W.C.
