The pressure switch is a critical safety component that monitors negative pressure created by the draft inducer motor. Once the inducer reaches proper speed and airflow is confirmed, the pressure switch closes to allow the ignition sequence to proceed. When this switch fails — or its sensing hose becomes cracked or clogged — the furnace will lock out before the igniter ever fires, leaving you with a cold home and a blinking fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single-stage draft pressure switch | Rated .27\" W.C. break \/ .42\" W.C. max make | Includes factory mounting bracket | Direct OEM replacement, no modifications required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a factory-genuine Carrier part (HK06WC069), calibrated to exact W.C. specifications for the PG8MAA048135ADJA.
