The pressure switch proves that the inducer motor has created sufficient negative draft pressure before the control board allows the ignition sequence to proceed. When this switch fails — or the port becomes blocked with condensate — the furnace will lock out before any heat is produced, often logging a fault code indicating a pressure switch error or failed inducer proving. Symptoms include the inducer running continuously with no spark, or the system cycling on and resetting without producing heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Close setpoint: 22\" W.C. | Open setpoint: 7\" W.C. | Lead length: 50\" | OEM Part Number: HK02ZB038 | Cross-reference: PS80-02-F0074\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier factory part.

Tools needed: flathead screwdriver, needle-nose pliers, multimeter (for pre-install continuity check).
