The Goodman A3468601 is genuine 3/16-inch inside-diameter pressure switch tubing for AMS80904BXA furnaces and compatible Goodman/Amana models. This flexible hose carries the vacuum signal between the inducer draft port and the pressure switch, allowing the switch to confirm proper venting before ignition. Cracked, hardened, or condensate-clogged tubing is a leading cause of pressure-switch lockout and the furnace failing to light.
Genuine Goodman tubing uses the correct wall thickness and high-temperature silicone that resists heat-soak hardening and condensate attack near the inducer. Generic vinyl hose can collapse under vacuum or crack quickly, triggering intermittent no-heat calls. For a reliable pressure signal, the OEM hose is the smart, low-cost fix.
Very Easy (1/5). Power off the furnace, slide the old hose off both barbs, and press the new tubing fully onto the inducer port and pressure switch. Route it with no low spots that can trap condensate. Takes just a few minutes and requires no tools.
