The Goodman/Amana A3468601 Pressure Switch Tubing is the OEM 3/16" inside-diameter draft-sensing hose for the AMH81005CNBA 80% AFUE gas furnace and compatible Goodman/Amana models. This small silicone/rubber tube connects the induced-draft blower's pressure tap to the pressure switch, letting the switch confirm that the inducer is moving combustion air before the control board allows ignition. Cracked, brittle, disconnected, or condensate-blocked tubing is a frequent cause of a furnace that won't start and reports a pressure-switch fault — a cheap part that prevents an expensive service call.
OEM vs. Generic: The genuine A3468601 uses the correct 3/16" ID and a heat- and condensate-resistant compound rated for the flue environment. Generic hose of the wrong diameter can leak at the barbs or degrade quickly near the inducer, returning the same no-start fault. At this price, the OEM tube is the smart replacement.
Install difficulty: Very easy (1/5). Pull the old tube off the barbed fittings and push the new one on — under 5 minutes. Shut off power first, route the tubing so it drains toward the switch, and confirm there are no kinks or low spots that could trap condensate.
