The Goodman A3468601 Pressure Switch Tubing is a genuine OEM 3/16-inch inner-diameter hose for the Amana/Goodman AMH80403ANBA gas furnace. This tubing carries the negative-pressure signal from the induced-draft motor to the pressure switch, proving that the flue is drafting properly before the control board energizes the igniter and gas valve. Cracked, kinked, or brittle tubing is a frequent cause of pressure-switch lockout faults.

Specifications

OEM Part Number: A3468601
Inner Diameter: 3/16 inch
Type: Pressure switch signal tubing / hose
Function: Draft-pressure signal transfer
Equipment: 80% AFUE gas furnace
Compatible Model: AMH80403ANBA and select Goodman/Amana units

OEM vs. Generic

The OEM A3468601 tubing is sized to the exact 3/16-inch bore and material spec so it seats securely on both barbs without splitting. Mismatched generic hose can leak the pressure signal and cause false lockouts. OEM ensures a reliable, airtight signal path.

Installation

Difficulty: Easy (1/5) — under 10 minutes. Disconnect power, pull the old hose from both ports, and press the new tubing fully onto the inducer and pressure-switch barbs.

Fits the AMH80403ANBA. Confirm your part number before purchasing.
