This flexible hose carries the negative-pressure signal from the inducer housing or collector box to the furnace pressure switch, allowing the control board to confirm proper venting and combustion airflow before the burners are allowed to fire.\u003c\/p\u003e\u003cp\u003eOver time, factory tubing can crack, harden, kink, or collapse from years of heat cycling, which produces nuisance lockouts, ignition failures, or a furnace that runs the inducer but never lights. Replacing the tube with the correct OEM part restores an accurate pressure signal and reliable ignition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner diameter:\u003c\/strong\u003e 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e heat-resistant silicone\/rubber hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e pressure switch signal line (inducer\/collector box to switch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Goodman\/Amana AMH81155CNAA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e A3468601\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Generic bulk tubing may match the diameter but often uses a lower temperature rating and looser wall tolerances, which can lead to premature hardening near the hot inducer and intermittent pressure faults. This genuine Goodman tube is spec'd for furnace-side heat and delivers a leak-free connection that seals correctly to the barbed fittings the first time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Easy (DIY-friendly). Shut off power and gas, pull the old tube from both barbs, route the new length the same way, and press it fully onto each fitting. Typical replacement takes under 10 minutes with no tools. Always verify correct furnace operation after service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057642324339,"sku":"GOODMAN-6000","price":6.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-16-id-pressure-switch-tubing-for-amh81155cnaa-a3468601","provider":"National HVAC Parts","version":"1.0","type":"link"}
