The Goodman A3468601 is a genuine OEM 3/16" inner-diameter pressure switch tubing designed for the AMS81155CXA gas furnace and compatible Goodman/Amana models. This flexible silicone hose connects the furnace pressure switch to the inducer assembly, allowing the switch to sense the negative pressure that confirms proper draft before the burners fire.

Over time, factory tubing can harden, crack, or become brittle from repeated heat cycling, causing nuisance pressure-switch lockouts and no-heat calls. Replacing it with the correct OEM part restores accurate pressure readings and reliable ignition.

  • Inner Diameter: 3/16 in.
  • Material: High-temperature silicone
  • Application: Pressure switch to inducer draft sensing
  • Fits: Goodman AMS81155CXA and compatible furnaces
  • OEM Part #: A3468601

OEM vs. Generic: Our genuine Goodman tubing is cut to the exact length and durometer specified by the manufacturer, ensuring a leak-free press fit. Generic hose is offered at a lower price point and works for most repairs, but may require trimming and can vary in wall thickness. For guaranteed draft-sensing accuracy, we recommend the OEM part.

Install Difficulty: Easy (1/5). Pull the old hose off both barbed fittings and press the new tubing on—no tools required. Always shut off power and gas before servicing.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMS81155CXA — A3468601?
Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMS81155CXA — A3468601. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the pressure switch tubing on my Goodman AMS81155CXA — A3468601?
Difficulty: Medium (20–30 min)
Step 1: Turn off power. Step 2: Locate pressure switch near draft inducer. Step 3: Note tubing orientation. Step 4: Disconnect tubing and wires. Step 5: Remove screw, install new switch. Step 6: Reconnect tubing and wires, restore power.
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.
Is this pressure switch tubing compatible with Bryant or Payne too?
Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Goodman pressure switch tubing?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
