The Goodman A3468601 is genuine OEM 3/16-inch ID pressure-switch tubing for the AMS80453ANA gas furnace and compatible Goodman/Amana models. This small-bore hose connects the draft-inducer/collector-box port to the pressure switch, carrying the vacuum signal that proves proper venting before the burners are allowed to light.

When the tubing hardens, cracks, kinks, or fills with condensate, the switch cannot sense adequate draft and the furnace short-cycles or locks out on a pressure-switch fault. Fresh OEM tubing restores an accurate vacuum signal and reliable ignition.

Specifications

OEM Part Number: A3468601
Type: Pressure-switch signal tubing / hose
Inside diameter: 3/16 inch
Material: High-temp flexible tubing
Fits: Goodman / Amana AMS80453ANA and compatible furnaces
Function: Carries draft vacuum signal to the pressure switch

OEM vs. Generic

Genuine Goodman tubing uses the correct bore and heat-rated compound so it holds an airtight vacuum without collapsing near the inducer. Generic hose can be too soft, kink at bends, or degrade in heat, leading to repeat lockouts. For a safety-interlock signal line, OEM tubing is the dependable choice.

Installation Difficulty

Easy (1/5). Power off the furnace, pull the old hose from the inducer port and pressure-switch nipple, cut the new tubing to the same length, and press it firmly onto both fittings with no kinks. A 10-minute repair; confirm normal ignition and no pressure-switch fault afterward.
