The Goodman A3468601 is a genuine OEM 3/16" inner-diameter pressure switch tubing designed for the AMH80904BNAC gas furnace and compatible Goodman/Amana models. This flexible hose connects the pressure switch to the inducer draft assembly, allowing the switch to sense proper venting before the furnace fires. Cracked, brittle, or disconnected tubing is a common cause of pressure-switch lockout faults and no-heat calls.

Specifications

Inner diameter: 3/16 inch
Application: Draft/inducer pressure sensing
Fit: Goodman AMH80904BNAC and compatible furnaces
Material: Heat-resistant flexible tubing
OEM part number: A3468601

OEM vs. Generic

Our OEM Goodman tubing is molded to the exact bore and wall thickness the furnace was engineered for, ensuring an airtight seal at both the switch port and inducer nipple. Generic bulk hose is a lower-cost option but may vary in flexibility and heat tolerance, which can lead to premature cracking near the hot inducer housing.

Installation Difficulty

Easy (1/5). Slip the old hose off both ports, cut the new tubing to length if needed, and press it on. No tools required beyond a nut driver to access the panel. A 5-minute job for most homeowners once power is off.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80904BNAC — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80904BNAC — 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 AMH80904BNAC — 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.
