Goodman A3468601 Pressure Switch Tubing (3/16" ID)

The A3468601 is genuine OEM 3/16" inside-diameter pressure switch tubing for the Goodman/Amana AMH81405DXCE gas furnace. This small hose carries the negative-pressure (draft) signal from the inducer housing or collector box to the pressure switch, allowing the switch to confirm proper venting before the burners fire. Cracked, brittle, kinked, or condensate-clogged tubing is a frequent cause of a furnace that fails to ignite and locks out on an open pressure switch.

Part number: A3468601 (OEM)
Inside diameter: 3/16 inch
Function: Transmits draft pressure signal to the pressure switch
Material: Heat- and condensate-resistant tubing
Fits: Goodman/Amana AMH81405DXCE and compatible furnaces

OEM vs. Generic

OEM tubing is cut and specified to the correct diameter and temperature rating for the furnace. Generic hose can be the wrong ID (causing leaks or slip-off) or degrade quickly near the hot inducer. Genuine A3468601 ensures a leak-free draft signal.

Installation Difficulty: Very Easy

Slide the old tubing off both ports and press the new length on. Route it away from hot surfaces and avoid sharp bends. Clear any condensate from the ports before reconnecting. Power and gas off before servicing.
