This flexible line connects the pressure switch to the inducer\/vent draft port and carries the negative-pressure signal that proves proper venting before the furnace allows ignition. Cracked, brittle, or clogged tubing is one of the most common causes of a stuck-open pressure switch and no-heat lockout.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Pressure\/draft sensing tubing\u003c\/li\u003e\n\u003cli\u003eInside diameter: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003eFunction: Connects pressure switch to inducer draft port\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMS80905CXA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eOEM part number: A3468601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e tubing uses the correct 3\/16\" ID and heat-rated material so it seals tightly on both ports and won't collapse or harden near the inducer. Generic tubing that is slightly oversized, undersized, or made of the wrong material can leak the pressure signal, causing intermittent lockouts that are difficult to diagnose.
