The tube transmits the negative pressure signal that proves the inducer is moving combustion air before the board allows ignition. Cracked, brittle, or clogged tubing produces false pressure-switch lockouts and no-heat calls — fresh OEM tubing restores reliable draft sensing.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: A3468601\u003c\/li\u003e\n\u003cli\u003eInner Diameter: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003eMaterial: Heat-resistant silicone\/rubber tubing\u003c\/li\u003e\n\u003cli\u003eFunction: Pressure switch signal line\u003c\/li\u003e\n\u003cli\u003eFits: Goodman DMS81155CNA and compatible models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM tubing is cut to the correct ID and length and rated for furnace-cabinet heat.
