This small hose connects the inducer\/vent port to the furnace pressure switch, allowing the switch to sense negative combustion-vent pressure before ignition is permitted. Cracked, brittle, kinked, or condensate-blocked tubing prevents the switch from closing, producing pressure-switch fault codes and no-heat lockouts. Replacing aged tubing is an inexpensive fix that restores accurate pressure sensing and safe operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e A3468601\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Model:\u003c\/strong\u003e AMH81405DNAB (Amana\/Goodman gas furnace)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter:\u003c\/strong\u003e 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Pressure switch sensing line\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-resistant flexible tubing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment Type:\u003c\/strong\u003e Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM tubing uses the correct 3\/16\" ID and a heat- and condensate-rated compound so it seals tightly at the switch and inducer ports and resists hardening near the burner box. Generic hardware-store tubing may have the wrong bore or lower heat rating, leading to loose fits, air leaks, or premature cracking that reintroduces nuisance lockouts. On a combustion-safety circuit, the correct OEM line is well worth the small cost.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e Cut power, slide the old tubing off both barbed ports, cut the new tubing to the same length, and press it firmly onto each port.
