This small but critical hose carries the negative pressure signal from the inducer draft port to the pressure switch, allowing the switch to confirm proper venting before the furnace ignites. Cracked, hardened, or disconnected tubing is one of the most common causes of a furnace that clicks but will not light.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInside diameter: 3\/16 inch (0.1875\")\u003c\/li\u003e\n\u003cli\u003eApplication: draft\/pressure switch sensing line\u003c\/li\u003e\n\u003cli\u003eMaterial: heat-resistant silicone hose\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana furnaces including AMH80704BNAB\u003c\/li\u003e\n\u003cli\u003ePart number: A3468601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is the factory-spec OEM tubing engineered to survive years of furnace heat cycling without hardening or collapsing. Bulk generic vinyl tubing may fit dimensionally but often stiffens and cracks under sustained heat, leading to intermittent pressure-switch faults. For a reliable long-term repair, OEM is the safe choice at a nearly identical price.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e Power down the furnace, pull the old hose off the inducer port and switch nipple, and slide the new tubing on with a firm push.
