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

The Goodman A3468601 is genuine OEM pressure switch tubing with a 3/16" inner diameter, designed as an exact-fit replacement for the Amana/Goodman AMH81405DXCB gas furnace and compatible models. This small but essential hose connects the pressure switch to the inducer/vent assembly so the switch can verify proper draft before allowing ignition. Cracked, brittle, or clogged tubing is a frequent cause of pressure-switch lockouts and no-heat faults.

OEM vs. Generic

Genuine OEM tubing uses the correct bore and heat-resistant material so it maintains an airtight signal path without collapsing or hardening near the inducer. Generic tubing may not seal properly or may degrade quickly, causing intermittent pressure-switch trips. OEM ensures a reliable draft signal.

Installation Difficulty

Very Easy (1/5) — A simple push-on hose replacement between the pressure switch and inducer port. Power down the furnace, remove the old tubing, and route the new hose without kinks. One of the quickest DIY furnace repairs.

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

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