Goodman A3468601 3/16 in. ID Pressure Switch Tubing

The Goodman A3468601 is genuine OEM 3/16 inch inside-diameter pressure switch tubing, cut and specified as a direct-fit replacement for the AMH80903BNAA gas furnace. This flexible hose connects the pressure switch to the inducer or vent tap, letting the switch sense proper draft before the burners fire. Cracked, hardened, or collapsed tubing is a frequent cause of ignition lockouts and no-heat calls — a fresh factory hose restores accurate pressure sensing.

Specifications

Part Number: A3468601
Inside Diameter: 3/16 in.
Function: Pressure switch sensing line
Application: 80% AFUE gas furnace draft sensing
Fits: Goodman / Amana AMH80903BNAA and compatible models
Type: OEM factory replacement

OEM vs. Generic

The OEM tubing uses heat- and moisture-resistant material rated for furnace flue conditions and matches the correct 3/16 in. bore for a snug, leak-free fit on the switch barbs. Generic hose may harden or soften at furnace temperatures, causing false trips. The factory part is inexpensive insurance for reliable operation.

Installation Difficulty

Very Easy (1 of 5). Pull the old hose off both barbs, route the new tube the same way, and press it on. No tools needed. Cut power before servicing and confirm the switch closes on startup.

My furnace shows a pressure switch error. What do I replace?

Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.

Should I use OEM or aftermarket for my Goodman pressure switch?
