This small-diameter tube connects the induced-draft blower (or collector box) to the pressure switch, allowing the switch to sense negative pressure and prove that the inducer is moving air before the burners are allowed to ignite. Cracked, brittle, or blocked tubing is a frequent cause of pressure-switch lockouts and ignition faults.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: A3468601\u003c\/li\u003e\n\u003cli\u003eComponent Type: Pressure switch \/ draft-sensing tubing\u003c\/li\u003e\n\u003cli\u003eInner Diameter: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003eMaterial: Heat- and moisture-resistant tubing\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMH80905CXCA and compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM A3468601 tubing is the correct 3\/16in ID and rated for the temperature and condensate exposure it sees on the draft circuit. Generic hardware-store hose may be the wrong bore (leaking the signal) or degrade quickly in the furnace environment, leading to repeat failures. Using the factory part ensures a proper seal and reliable pressure sensing.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — A 5-minute job.
