Genuine OEM Goodman A3468601 pressure switch tubing is the factory-spec sensing hose used on the AMS80704BNA 80% multi-position gas furnace and many related Goodman/Amana models. This 3/16 inch inside-diameter tube carries the negative pressure signal between the inducer housing (or collector box) and the furnace pressure switch, allowing the switch to confirm proper venting before the burners fire.

Over time this tubing can crack, harden, or become brittle from repeated heat cycling, causing intermittent pressure-switch lockouts and nuisance no-heat calls. Replacing it with the correct OEM tube restores a reliable air seal and accurate pressure sensing.

  • Part number: A3468601
  • Inside diameter: 3/16 in
  • Function: Pressure/draft switch sensing line
  • Material: Heat-resistant flexible tubing
  • Fits: Goodman AMS80704BNA and compatible furnaces

OEM vs. Generic: The genuine Goodman tube is cut and formulated to the exact length, wall thickness, and temperature rating specified by the factory, ensuring a leak-free press-fit over the switch and inducer barbs. Generic bulk tubing may fit loosely, harden faster, or fail to hold a stable pressure signal — leading to repeat failures. For a critical safety-sensing component, OEM is the reliable choice.

Install difficulty: Easy — a DIY-friendly replacement. Power down the furnace, slip the old tube off both barbs, and press the new tube fully onto each fitting. No tools required. Always verify furnace operation and pressure-switch closure after installation.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMS80704BNA — A3468601?
Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMS80704BNA — 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 AMS80704BNA — 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.
