The Goodman A3468601 is genuine OEM 3/16-inch inside-diameter pressure switch tubing for the AMH80453AXCA gas furnace and related Amana and Goodman models. This hose carries the negative-pressure signal from the inducer housing or collector box to the furnace pressure switch, allowing the control board to confirm proper venting before ignition.

Over time this tubing hardens, cracks, or clogs with condensate and soot, causing intermittent pressure-switch lockouts and no-heat calls. Fresh OEM tubing restores a clean, accurate draft signal.

Specifications

Part number: A3468601
Type: Pressure switch signal tubing
Inside diameter: 3/16 in.
Fits: AMH80453AXCA and related Amana/Goodman furnaces

OEM vs. Generic

OEM tubing is sized to the exact port diameters and rated for the heat and condensate exposure near the inducer. Generic hose can be the wrong bore, kink at the routing bends, or embrittle quickly — reintroducing the same intermittent fault. OEM ensures a lasting, leak-free connection.

Installation

Difficulty: Easy (1/5). Power off the furnace, pull the old tube from both barbed ports, route the new tube along the same path avoiding sharp bends and hot surfaces, and push it fully onto each fitting. About a 10-minute job with no special tools. Cycle the furnace and confirm the pressure switch closes on a call for heat.

Genuine OEM replacement part. Verify your model and serial before ordering.
