This OEM Goodman A3468601 pressure switch tubing is a genuine 3/16-inch inside-diameter silicone hose used to connect the pressure switch to the inducer/collector box on AMH80903BNAB furnaces and other compatible Goodman and Amana 80% AFUE gas models. When this tubing cracks, hardens, or clogs, the furnace can fail to prove draft and lock out on a pressure-switch fault — restoring a clean, sealed hose is the fastest way to get reliable ignition back.

Specifications

Inside diameter: 3/16 in
Material: high-temperature silicone tubing
Function: pressure switch to inducer pressure tap
Fits: Goodman/Amana AMH80903BNAB and compatible 80% furnaces
OEM part number: A3468601

OEM vs. Generic

The OEM Goodman A3468601 is spec-matched for the exact bore and temperature rating of your furnace, ensuring a leak-free seal on the factory barbs. Generic universal tubing may vary in wall thickness and heat tolerance, which can cause slow leaks and nuisance pressure-switch trips. For a trouble-free repair, genuine OEM is recommended.

Installation Difficulty

Easy (DIY-friendly). Power down the furnace, slide the old hose off both barbs, and press the new tubing fully onto each fitting. No tools required. Always confirm the switch operates and the furnace proves draft before returning to service.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80903BNAB — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80903BNAB — 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 AMH80903BNAB — 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.
