This small hose carries the vacuum signal that proves proper venting before the burners fire. When the tubing cracks, hardens, kinks, or fills with condensate, the pressure switch fails to close and the furnace locks out with a no-ignition fault — even though the inducer is running fine.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside diameter:\u003c\/strong\u003e 3\/16 in (0.1875 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Draft\/pressure sensing line to the pressure switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-resistant flexible tubing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Goodman\/Amana GMNT120-5 and compatible furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Inducer-to-pressure-switch connection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine OEM A3468601 uses the correct 3\/16 in ID and heat-rated material to seal tightly at both the inducer tap and switch port without collapsing under vacuum. Generic hose of the wrong durometer or diameter can slip, leak, or soften near the hot inducer, reintroducing the very fault you're trying to fix.
